85080978 divided by 231 
We want to figure out the number of times 85080978 can be divided by 231.

Step 1:
231 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 231

Advancing to step 2:
When dividing 85 by 231, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 231

Let's proceed to step 3:
When dividing 850 by 231, we get 3 with a remainder of 157.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 693 from 850 leaves us with 157.
Fetch the next digit (8) from the dividend, attach it to 157 and continue: 1578 / 231

Going ahead to step 4:
231 can be fit into 1578 6 times, resulting in a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 1386 away from 1578, we end up with 192.
Grab the next digit (0) from the dividend, add it to 192, then carry on: 1920 / 231

Advancing to step 5:
If we divide 1920 by 231, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 368.0
Subtract 1848 from 1920 to get 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 231

Moving on to step 6:
231 can be fit into 729 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3683.0
Subtracting 693 from 729 leaves us with 36.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 231

Moving on to step 7:
367 divided by 231 is 1 with a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 36831.0
Subtracting 231 from 367 leaves us with 136.
Bring next digit (8) of the dividend behind the 136 and repeat the process: 1368 / 231

On to step 8:
If we divide 1368 by 231, we get 5 and a remainder of 213.
The next digit of our result is 5. 
Result so far: 368315.0
If we subtract 1155 from 1368, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 9:
231 can be fit into 2130 9 times, resulting in a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 368315.9
Subtracting 2079 from 2130 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
510 divided by 231 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 368315.92
The remainder is 48 after subtracting 462 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
The number 231 fits into 480 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 368315.922
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 368315.922, with a leftover of 0.0018.
