51759615 divided by 630 
Our goal is to divide 51759615 by 630.

Advancing to step 1:
If we divide 5 by 630, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 630

On to step 2:
When dividing 51 by 630, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 630

On to step 3:
When dividing 517 by 630, we get 0 with a remainder of 517.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 517 leaves us with 517.
Bring next digit (5) of the dividend behind the 517 and repeat the process: 5175 / 630

Moving on to step 4:
630 goes into 5175 8 times with a remainder of 135.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 5040 from 5175 leaves us with 135.
Include the next digit (9) from the dividend after 135, then repeat: 1359 / 630

On to step 5:
When dividing 1359 by 630, we get 2 with a remainder of 99.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we subtract 1260 from 1359, we get 99.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 630

Going ahead to step 6:
630 goes into 996 1 times with a remainder of 366.
Write down 1 as next digit of the result. 
Result so far: 821.0
Subtracting 630 from 996 leaves us with 366.
Grab the next digit (1) from the dividend, add it to 366, then carry on: 3661 / 630

Moving on to step 7:
630 goes into 3661 5 times with a remainder of 511.
Put 5 as the next digit of the answer. 
Result so far: 8215.0
The remainder is 511 after subtracting 3150 from 3661.
Append the next digit (5) from the dividend to 511 and continue with: 5115 / 630

Going ahead to step 8:
When dividing 5115 by 630, we get 8 with a remainder of 75.
The number 8 becomes the next digit in our result. 
Result so far: 82158.0
If we take 5040 away from 5115, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
The number 630 fits into 750 1 times, leaving a remainder of 120.
The next digit of our result is 1. 
Result so far: 82158.1
Subtracting 630 from 750 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
1200 divided by 630 is 1 with a remainder of 570.
Put 1 as the next digit of the answer. 
Result so far: 82158.11
Deduct 630 from 1200 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The quotient of the division is 82158.11, and the remainder is 0.57.
