We're dividing 77936599 by 231 
We want to divide 77936599 by 231.

Advancing to step 1:
When dividing 7 by 231, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 231

Advancing to step 2:
231 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 231

Going ahead to step 3:
If we divide 779 by 231, we get 3 and a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 693 from 779, we get 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 231

Moving on to step 4:
231 can be fit into 863 3 times, resulting in a remainder of 170.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 693 from 863 leaves us with 170.
Include the next digit (6) from the dividend after 170, then repeat: 1706 / 231

Going ahead to step 5:
231 can be fit into 1706 7 times, resulting in a remainder of 89.
Record the quotient 7 as the next digit in the result. 
Result so far: 337.0
Deduct 1617 from 1706 and we're left with 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 231

Advancing to step 6:
The number 231 fits into 895 3 times, leaving a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 3373.0
If we take 693 away from 895, we end up with 202.
Append the next digit (9) from the dividend to 202 and continue with: 2029 / 231

Advancing to step 7:
If we divide 2029 by 231, we get 8 and a remainder of 181.
The next digit of our result is 8. 
Result so far: 33738.0
Subtract 1848 from 2029 to get 181.
Fetch the next digit (9) from the dividend, attach it to 181 and continue: 1819 / 231

Let's proceed to step 8:
When dividing 1819 by 231, we get 7 with a remainder of 202.
Use 7 as the next digit of our solution. 
Result so far: 337387.0
If we subtract 1617 from 1819, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 9:
2020 divided by 231 is 8 with a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 337387.8
The remainder is 172 after subtracting 1848 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
When dividing 1720 by 231, we get 7 with a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 337387.87
If we subtract 1617 from 1720, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 11:
The number 231 fits into 1030 4 times, leaving a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 337387.874
Subtracting 924 from 1030 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 12:
231 can be fit into 1060 4 times, resulting in a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 337387.8744
If we subtract 924 from 1060, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 337387.8744 with a remainder of 0.00136.
