We look at the division of 831453 by 63 
We want to divide 831453 by 63.

Moving on to step 1:
When dividing 8 by 63, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 63

Advancing to step 2:
The number 63 fits into 83 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 63 from 83 to get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 63

Moving on to step 3:
When dividing 201 by 63, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 189 from 201 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 63

Advancing to step 4:
124 divided by 63 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we take 63 away from 124, we end up with 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 63

Moving on to step 5:
63 can be fit into 615 9 times, resulting in a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 1319.0
If we subtract 567 from 615, we get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 63

On to step 6:
483 divided by 63 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 13197.0
If we take 441 away from 483, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
If we divide 420 by 63, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 13197.6
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
If we divide 420 by 63, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 13197.66
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 13197.66, with a leftover of 0.042.
