We look at the division of 372686 by 18 
We're looking to find how many times 18 goes into 372686.

Moving on to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 18

Step 2:
The number 18 fits into 37 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 1 after subtracting 36 from 37.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 18

Advancing to step 3:
The number 18 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 12 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 18

Advancing to step 4:
18 can be fit into 126 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 207.0
If we subtract 126 from 126, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 18

Going ahead to step 5:
The number 18 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 2070.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 18

Going ahead to step 6:
If we divide 86 by 18, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 20704.0
Subtract 72 from 86 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
18 goes into 140 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 20704.7
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 20704.77
Deduct 126 from 140 and we're left 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.

The final outcome is 20704.77, with a leftover of 0.014.
