We divide 108166 by 86
Let's see how many times 86 fits into 108166.

Moving on to step 1:
1 divided by 86 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 86

Step 2:
If we divide 10 by 86, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 86

Going ahead to step 3:
The number 86 fits into 108 1 times, leaving 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.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 86

Moving on to step 4:
86 can be fit into 221 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 172 from 221 and we're left with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 86

Advancing to step 5:
The number 86 fits into 496 5 times, leaving a remainder of 66.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 430 from 496 leaves us with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 86

Let's proceed to step 6:
86 can be fit into 666 7 times, resulting in a remainder of 64.
The next digit of our result is 7. 
Result so far: 1257.0
If we take 602 away from 666, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
86 goes into 640 7 times with a remainder of 38.
The next digit of our result is 7. 
Result so far: 1257.7
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
When dividing 380 by 86, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1257.74
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
When dividing 360 by 86, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1257.744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 1257.744, and the remainder is 0.0016.
