We look at the division of 77915403 by 856 
We want to divide 77915403 by 856.

On to step 1:
7 divided by 856 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 856

Advancing to step 2:
77 divided by 856 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 856

Going ahead to step 3:
The number 856 fits into 779 0 times, leaving a remainder of 779.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 779 leaves us with 779.
Fetch the next digit (1) from the dividend, attach it to 779 and continue: 7791 / 856

On to step 4:
856 can be fit into 7791 9 times, resulting in a remainder of 87.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7704 away from 7791, we end up with 87.
Fetch the next digit (5) from the dividend, attach it to 87 and continue: 875 / 856

On to step 5:
If we divide 875 by 856, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 856 from 875, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 856

Advancing to step 6:
If we divide 194 by 856, we get 0 and a remainder of 194.
The number 0 becomes the next digit in our result. 
Result so far: 910.0
If we take 0 away from 194, we end up with 194.
Take the next digit (0) from the dividend and append it to 194, then repeat: 1940 / 856

Let's proceed to step 7:
856 goes into 1940 2 times with a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 9102.0
Subtracting 1712 from 1940 leaves us with 228.
Grab the next digit (3) from the dividend, add it to 228, then carry on: 2283 / 856

Moving on to step 8:
2283 divided by 856 is 2 with a remainder of 571.
Write down 2 as next digit of the result. 
Result so far: 91022.0
If we subtract 1712 from 2283, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Advancing to step 9:
The number 856 fits into 5710 6 times, leaving a remainder of 574.
Record the quotient 6 as the next digit in the result. 
Result so far: 91022.6
Subtracting 5136 from 5710 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 10:
5740 divided by 856 is 6 with a remainder of 604.
Use 6 as the next digit of our solution. 
Result so far: 91022.66
Deduct 5136 from 5740 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The quotient of the division is 91022.66, and the remainder is 0.604.
