86907927 ÷ 231 
We're looking to find how many times 231 goes into 86907927.

Advancing to step 1:
The number 231 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 231

Going ahead to step 2:
If we divide 86 by 231, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 231

Going ahead to step 3:
The number 231 fits into 869 3 times, leaving a remainder of 176.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 693 from 869, we get 176.
Include the next digit (0) from the dividend after 176, then repeat: 1760 / 231

On to step 4:
1760 divided by 231 is 7 with a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 1617 away from 1760, we end up with 143.
Bring next digit (7) of the dividend behind the 143 and repeat the process: 1437 / 231

On to step 5:
1437 divided by 231 is 6 with a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 376.0
Subtracting 1386 from 1437 leaves us with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 231

Let's proceed to step 6:
If we divide 519 by 231, we get 2 and a remainder of 57.
The next digit of our result is 2. 
Result so far: 3762.0
Subtract 462 from 519 to get 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 231

Step 7:
231 can be fit into 572 2 times, resulting in a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 37622.0
Subtract 462 from 572 to get 110.
Fetch the next digit (7) from the dividend, attach it to 110 and continue: 1107 / 231

Moving on to step 8:
If we divide 1107 by 231, we get 4 and a remainder of 183.
Put 4 as the next digit of the answer. 
Result so far: 376224.0
Deduct 924 from 1107 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
The number 231 fits into 1830 7 times, leaving a remainder of 213.
Record the quotient 7 as the next digit in the result. 
Result so far: 376224.7
Deduct 1617 from 1830 and we're left with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 10:
231 can be fit into 2130 9 times, resulting in a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 376224.79
If we subtract 2079 from 2130, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
The number 231 fits into 510 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 376224.792
Subtracting 462 from 510 leaves us with 48.
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 12:
The number 231 fits into 480 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 376224.7922
Subtract 462 from 480 to get 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 result is 376224.7922 with a remainder of 0.00018.
