51360479 ÷ 791 
We're looking to find how many times 791 goes into 51360479.

Advancing to step 1:
5 divided by 791 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 791

Going ahead to step 2:
51 divided by 791 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 791

Moving on to step 3:
The number 791 fits into 513 0 times, leaving a remainder of 513.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 513 after subtracting 0 from 513.
Append the next digit (6) from the dividend to 513 and continue with: 5136 / 791

Step 4:
When dividing 5136 by 791, we get 6 with a remainder of 390.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 4746 from 5136, we get 390.
Grab the next digit (0) from the dividend, add it to 390, then carry on: 3900 / 791

Advancing to step 5:
When dividing 3900 by 791, we get 4 with a remainder of 736.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 3164 from 3900, we get 736.
Fetch the next digit (4) from the dividend, attach it to 736 and continue: 7364 / 791

Going ahead to step 6:
When dividing 7364 by 791, we get 9 with a remainder of 245.
Record the quotient 9 as the next digit in the result. 
Result so far: 649.0
If we subtract 7119 from 7364, we get 245.
Take the next digit (7) from the dividend and append it to 245, then repeat: 2457 / 791

Moving on to step 7:
791 goes into 2457 3 times with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 6493.0
If we subtract 2373 from 2457, we get 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 791

On to step 8:
When dividing 849 by 791, we get 1 with a remainder of 58.
The next digit of our result is 1. 
Result so far: 64931.0
Subtracting 791 from 849 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 9:
791 can be fit into 580 0 times, resulting in a remainder of 580.
Record the quotient 0 as the next digit in the result. 
Result so far: 64931.0
The remainder is 580 after subtracting 0 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 10:
5800 divided by 791 is 7 with a remainder of 263.
The next digit of our result is 7. 
Result so far: 64931.07
Subtract 5537 from 5800 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 11:
The number 791 fits into 2630 3 times, leaving a remainder of 257.
The number 3 becomes the next digit in our result. 
Result so far: 64931.073
If we subtract 2373 from 2630, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 12:
The number 791 fits into 2570 3 times, leaving a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 64931.0733
Deduct 2373 from 2570 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Our division results in 64931.0733 with a remaining 0.00197.
