108665 divided by 86 
We want to divide 108665 by 86.

Step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 86

On to step 2:
When dividing 10 by 86, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 86

Moving on to step 3:
When dividing 108 by 86, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 86 away from 108, we end up with 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 86

Let's proceed to step 4:
The number 86 fits into 226 2 times, leaving a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 172 from 226 leaves us with 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 86

Going ahead to step 5:
86 can be fit into 546 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtracting 516 from 546 leaves us with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 86

Advancing to step 6:
The number 86 fits into 305 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 1263.0
Subtract 258 from 305 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
When dividing 470 by 86, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1263.5
If we subtract 430 from 470, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
When dividing 400 by 86, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 1263.54
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
If we divide 560 by 86, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1263.546
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
440 divided by 86 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1263.5465
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1263.54651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1263.546511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 1263.546511, with a leftover of 5.4e-06.
