We look at the division of 37118 by 20 
We're looking to find how many times 20 goes into 37118.

Step 1:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 20

Moving on to step 2:
37 divided by 20 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 20 from 37 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 20

Going ahead to step 3:
171 divided by 20 is 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 160 from 171, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 20

Let's proceed to step 4:
20 goes into 111 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we take 100 away from 111, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 20

Let's proceed to step 5:
If we divide 118 by 20, we get 5 and a remainder of 18.
The next digit of our result is 5. 
Result so far: 1855.0
The remainder is 18 after subtracting 100 from 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 6:
When dividing 180 by 20, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1855.9
Subtract 180 from 180 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.

Moving on to step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1855.9
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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1855.9
If we subtract 0 from 0, 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.

The final outcome is 1855.9, with a leftover of 0.0.
