372100 ÷ 18 
We're looking to find how many times 18 goes into 372100.

Going ahead to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 18

Let's proceed to step 2:
37 divided by 18 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 36 from 37 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 18

Advancing to step 3:
18 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 12, we end up with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 18

Moving on to step 4:
18 can be fit into 121 6 times, resulting in a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 206.0
Deduct 108 from 121 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 18

Step 5:
If we divide 130 by 18, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 2067.0
Deduct 126 from 130 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 18

Moving on to step 6:
When dividing 40 by 18, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 20672.0
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 18, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 20672.2
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 18 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 20672.22
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 20672.22 with a remainder of 0.004.
