37997 divided by 20 
We're looking to find how many times 20 goes into 37997.

Advancing to step 1:
20 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
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 / 20

On to step 2:
37 divided by 20 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 17 after subtracting 20 from 37.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 20

Moving on to step 3:
The number 20 fits into 179 8 times, leaving a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 160 from 179 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 20

On to step 4:
If we divide 199 by 20, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 189.0
The remainder is 19 after subtracting 180 from 199.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 20

On to step 5:
When dividing 197 by 20, we get 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 1899.0
Subtract 180 from 197 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 6:
The number 20 fits into 170 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1899.8
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1899.85
If we subtract 100 from 100, 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.

Let's proceed to step 8:
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: 1899.85
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1899.85
Subtracting 0 from 0 leaves us with 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 1899.85 with a remaining 0.0.
