We look at the division of 77920505 by 331 
Our goal is to divide 77920505 by 331.

Advancing to step 1:
7 divided by 331 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 331

Advancing to step 2:
The number 331 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 331

Moving on to step 3:
779 divided by 331 is 2 with a remainder of 117.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 662 from 779 leaves us with 117.
Fetch the next digit (2) from the dividend, attach it to 117 and continue: 1172 / 331

Step 4:
1172 divided by 331 is 3 with a remainder of 179.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 179 after subtracting 993 from 1172.
Append the next digit (0) from the dividend to 179 and continue with: 1790 / 331

Step 5:
If we divide 1790 by 331, we get 5 and a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 235.0
Subtracting 1655 from 1790 leaves us with 135.
Include the next digit (5) from the dividend after 135, then repeat: 1355 / 331

Moving on to step 6:
331 can be fit into 1355 4 times, resulting in a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 2354.0
If we subtract 1324 from 1355, we get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 331

Moving on to step 7:
310 divided by 331 is 0 with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 23540.0
Subtracting 0 from 310 leaves us with 310.
Include the next digit (5) from the dividend after 310, then repeat: 3105 / 331

Advancing to step 8:
The number 331 fits into 3105 9 times, leaving a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 235409.0
If we take 2979 away from 3105, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
The number 331 fits into 1260 3 times, leaving a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 235409.3
If we take 993 away from 1260, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 10:
If we divide 2670 by 331, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 235409.38
Subtracting 2648 from 2670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
If we divide 220 by 331, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 235409.38
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
331 can be fit into 2200 6 times, resulting in a remainder of 214.
The next digit of our result is 6. 
Result so far: 235409.3806
If we take 1986 away from 2200, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 13:
2140 divided by 331 is 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 235409.38066
Subtracting 1986 from 2140 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Our division results in 235409.38066 with a remaining 0.000154.
