We look at the division of 10107819 by 791 
Let's see how many times 791 fits into 10107819.

Moving on to step 1:
The number 791 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 791

Let's proceed to step 2:
If we divide 10 by 791, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 791

Step 3:
If we divide 101 by 791, we get 0 and a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 101 and we're left with 101.
Fetch the next digit (0) from the dividend, attach it to 101 and continue: 1010 / 791

On to step 4:
791 goes into 1010 1 times with a remainder of 219.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 791 from 1010 and we're left with 219.
Fetch the next digit (7) from the dividend, attach it to 219 and continue: 2197 / 791

Advancing to step 5:
If we divide 2197 by 791, we get 2 and a remainder of 615.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1582 from 2197, we get 615.
Bring next digit (8) of the dividend behind the 615 and repeat the process: 6158 / 791

Moving on to step 6:
791 goes into 6158 7 times with a remainder of 621.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
The remainder is 621 after subtracting 5537 from 6158.
Take the next digit (1) from the dividend and append it to 621, then repeat: 6211 / 791

On to step 7:
791 can be fit into 6211 7 times, resulting in a remainder of 674.
The next digit of our result is 7. 
Result so far: 1277.0
Deduct 5537 from 6211 and we're left with 674.
Grab the next digit (9) from the dividend, add it to 674, then carry on: 6749 / 791

Step 8:
791 can be fit into 6749 8 times, resulting in a remainder of 421.
The number 8 becomes the next digit in our result. 
Result so far: 12778.0
Deduct 6328 from 6749 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 9:
791 can be fit into 4210 5 times, resulting in a remainder of 255.
The next digit of our result is 5. 
Result so far: 12778.5
Subtract 3955 from 4210 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 10:
791 can be fit into 2550 3 times, resulting in a remainder of 177.
Record the quotient 3 as the next digit in the result. 
Result so far: 12778.53
The remainder is 177 after subtracting 2373 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 11:
The number 791 fits into 1770 2 times, leaving a remainder of 188.
Use 2 as the next digit of our solution. 
Result so far: 12778.532
Subtracting 1582 from 1770 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 12:
If we divide 1880 by 791, we get 2 and a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 12778.5322
Subtracting 1582 from 1880 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Our division results in 12778.5322 with a remaining 0.00298.
