Let's divide 77796161 by 831
Our goal is to divide 77796161 by 831.

Let's proceed to step 1:
If we divide 7 by 831, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 831

Step 2:
When dividing 77 by 831, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 831

Let's proceed to step 3:
777 divided by 831 is 0 with a remainder of 777.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 777 to get 777.
Append the next digit (9) from the dividend to 777 and continue with: 7779 / 831

Step 4:
If we divide 7779 by 831, we get 9 and a remainder of 300.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 300 after subtracting 7479 from 7779.
Grab the next digit (6) from the dividend, add it to 300, then carry on: 3006 / 831

Advancing to step 5:
831 can be fit into 3006 3 times, resulting in a remainder of 513.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 2493 from 3006 leaves us with 513.
Fetch the next digit (1) from the dividend, attach it to 513 and continue: 5131 / 831

Let's proceed to step 6:
831 goes into 5131 6 times with a remainder of 145.
Put 6 as the next digit of the answer. 
Result so far: 936.0
If we take 4986 away from 5131, we end up with 145.
Grab the next digit (6) from the dividend, add it to 145, then carry on: 1456 / 831

Going ahead to step 7:
If we divide 1456 by 831, we get 1 and a remainder of 625.
The number 1 becomes the next digit in our result. 
Result so far: 9361.0
Subtracting 831 from 1456 leaves us with 625.
Fetch the next digit (1) from the dividend, attach it to 625 and continue: 6251 / 831

Let's proceed to step 8:
831 goes into 6251 7 times with a remainder of 434.
The number 7 becomes the next digit in our result. 
Result so far: 93617.0
Deduct 5817 from 6251 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 9:
831 can be fit into 4340 5 times, resulting in a remainder of 185.
The next digit of our result is 5. 
Result so far: 93617.5
Deduct 4155 from 4340 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 10:
1850 divided by 831 is 2 with a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 93617.52
The remainder is 188 after subtracting 1662 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
If we divide 1880 by 831, we get 2 and a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 93617.522
Subtracting 1662 from 1880 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final result is 93617.522 with a remainder of 0.0218.
