We're dividing 109899 by 86 
We're looking to find how many times 86 goes into 109899.

Going ahead to step 1:
86 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 86

On to step 2:
10 divided by 86 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 86

Going ahead to step 3:
The number 86 fits into 109 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 86 from 109 leaves us with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 86

Let's proceed to step 4:
When dividing 238 by 86, we get 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 172 from 238 and we're left with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 86

Let's proceed to step 5:
86 can be fit into 669 7 times, resulting in a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtract 602 from 669 to get 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 86

On to step 6:
The number 86 fits into 679 7 times, leaving a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 1277.0
Subtract 602 from 679 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 7:
When dividing 770 by 86, we get 8 with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 1277.8
Deduct 688 from 770 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
820 divided by 86 is 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1277.89
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1277.895
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1277.8953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
If we divide 420 by 86, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 1277.89534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
If we divide 760 by 86, we get 8 and a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 1277.895348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
86 can be fit into 720 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 1277.8953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 1277.8953488, with a leftover of 3.2e-07.
