We look at the division of 106686 by 18 
We're looking to find how many times 18 goes into 106686.

Let's proceed to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 18

Let's proceed to step 2:
18 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 18

On to step 3:
106 divided by 18 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 90 from 106, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 18

Moving on to step 4:
If we divide 166 by 18, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 162 from 166 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 18

Step 5:
If we divide 48 by 18, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 592.0
Subtracting 36 from 48 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Moving on to step 6:
18 can be fit into 126 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 5927.0
If we subtract 126 from 126, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5927.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 18, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5927.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5927.0 with a remaining 0.0.
