195 ÷ 15
15
195
We are dividing by 15, so I
am going to write down
the times tables for 15.
You will see why in a
minute!
15 30 45 60 75 90 105 120 135
15 into 1 won’t go (it goes 0 times) So put a ‘0’ above the (1).

15 into 19 goes 1 time. Put a ‘1’ above the number (9).

Write the number 15 under the sum you have just worked out (19). You
write 15 because you need to find the remainder.

Subtract 15 by 19 to find the remainder. Write the number ‘4’ underneath
correct column.

So far we have dealt with the 1 and 9, so we now need to deal with
the last number, ‘5’. Write the number ‘5’ next to the remainder of
‘4’.

How many 15’s go into 45? The answer would be 3. So you would
write the ‘3’ above the horizontal line, next to the ‘1’.
There isn’t a remainder, so the sum is finished!15

How to work it out:
777 ÷ 21
21
777
We are dividing by 21, so I
am going to write down
the times tables for 21.
21 42 63 84 105 126 147 168 189
21 into 7 won’t go. So put a ‘0’ above the (7).

Now its 21 into 77. It goes 3 times (63). Write the 3 next to the ‘0’.

Write the number 63 under the sum you have just worked out (77). You
write 63 because you need to find the remainder.

Subtract 63 by 77 to find the remainder. Write the number ‘14’ underneath
correct column.

So far we have dealt with the 7 and 7, so we now need to deal with
the last number, ‘7’. Write the number ‘7’ next to the remainder of
‘14’.

How many 21’s go into 147? The answer would be 7. So you would
write the ‘7’ above the horizontal line, next to the ‘3’.
There isn’t a remainder, so the sum is finished!21
