631235 divided by 15 
We want to divide 631235 by 15.

Moving on to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 15

Step 2:
15 goes into 63 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 3 after subtracting 60 from 63.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Moving on to step 3:
31 divided by 15 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 1 after subtracting 30 from 31.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 15

On to step 4:
15 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 420.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 15

Step 5:
When dividing 123 by 15, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 4208.0
If we subtract 120 from 123, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 15

Advancing to step 6:
35 divided by 15 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 42082.0
Subtracting 30 from 35 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 42082.3
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 42082.33
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 42082.33, with a leftover of 0.005.
