We look at the division of 108107 by 86 
We want to figure out the number of times 108107 can be divided by 86.

Moving on to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 86

Let's proceed to step 2:
86 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 86

Step 3:
When dividing 108 by 86, we get 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 86 from 108 to get 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 86

Going ahead to step 4:
221 divided by 86 is 2 with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 172 from 221 leaves us with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 86

Going ahead to step 5:
The number 86 fits into 490 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtract 430 from 490 to get 60.
Grab the next digit (7) from the dividend, add it to 60, then carry on: 607 / 86

On to step 6:
86 goes into 607 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 1257.0
If we subtract 602 from 607, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
86 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1257.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
If we divide 500 by 86, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1257.05
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
The number 86 fits into 700 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1257.058
Deduct 688 from 700 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
When dividing 120 by 86, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1257.0581
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
340 divided by 86 is 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 1257.05813
Subtract 258 from 340 to get 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 12:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 1257.058139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
86 goes into 460 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1257.0581395
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.

Let's proceed to step 14:
When dividing 300 by 86, we get 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1257.05813953
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.

The final result is 1257.05813953 with a remainder of 4.2e-08.
