Let's divide 102186 by 86
Let's see how many times 86 fits into 102186.

Step 1:
86 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 86

Advancing to step 2:
When dividing 10 by 86, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 86

Advancing to step 3:
If we divide 102 by 86, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 86 from 102 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 86

Moving on to step 4:
If we divide 161 by 86, we get 1 and a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 86 from 161 to get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 86

Advancing to step 5:
86 can be fit into 758 8 times, resulting in a remainder of 70.
The next digit of our result is 8. 
Result so far: 118.0
Subtracting 688 from 758 leaves us with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 86

Let's proceed to step 6:
86 goes into 706 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 1188.0
If we take 688 away from 706, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 86, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1188.2
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
86 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1188.2
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
86 goes into 800 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 1188.209
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1188.2093
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
If we divide 20 by 86, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1188.2093
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
86 goes into 200 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1188.209302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 1188.2093023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
86 goes into 220 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 1188.20930232
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 1188.20930232 with a remaining 4.8e-08.
