We're dividing 79457937 by 772 
We want to divide 79457937 by 772.

On to step 1:
The number 772 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 772

Advancing to step 2:
If we divide 79 by 772, we get 0 and a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 772

On to step 3:
The number 772 fits into 794 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 772 from 794 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 772

Going ahead to step 4:
If we divide 225 by 772, we get 0 and a remainder of 225.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 225 after subtracting 0 from 225.
Grab the next digit (7) from the dividend, add it to 225, then carry on: 2257 / 772

Going ahead to step 5:
If we divide 2257 by 772, we get 2 and a remainder of 713.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 1544 from 2257 to get 713.
Include the next digit (9) from the dividend after 713, then repeat: 7139 / 772

On to step 6:
If we divide 7139 by 772, we get 9 and a remainder of 191.
Write down 9 as next digit of the result. 
Result so far: 1029.0
If we take 6948 away from 7139, we end up with 191.
Append the next digit (3) from the dividend to 191 and continue with: 1913 / 772

Let's proceed to step 7:
If we divide 1913 by 772, we get 2 and a remainder of 369.
The number 2 becomes the next digit in our result. 
Result so far: 10292.0
Deduct 1544 from 1913 and we're left with 369.
Append the next digit (7) from the dividend to 369 and continue with: 3697 / 772

Let's proceed to step 8:
When dividing 3697 by 772, we get 4 with a remainder of 609.
Put 4 as the next digit of the answer. 
Result so far: 102924.0
Subtract 3088 from 3697 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 9:
772 can be fit into 6090 7 times, resulting in a remainder of 686.
Use 7 as the next digit of our solution. 
Result so far: 102924.7
If we subtract 5404 from 6090, we get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Advancing to step 10:
772 goes into 6860 8 times with a remainder of 684.
Put 8 as the next digit of the answer. 
Result so far: 102924.78
If we take 6176 away from 6860, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 11:
The number 772 fits into 6840 8 times, leaving a remainder of 664.
The number 8 becomes the next digit in our result. 
Result so far: 102924.788
Subtracting 6176 from 6840 leaves us with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

The final outcome is 102924.788, with a leftover of 0.0664.
