We look at the division of 637499 by 20 
We want to divide 637499 by 20.

Moving on to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Advancing to step 2:
63 divided by 20 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 60 away from 63, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

Let's proceed to step 3:
20 goes into 37 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 20 from 37 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 20

Advancing to step 4:
The number 20 fits into 174 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 318.0
The remainder is 14 after subtracting 160 from 174.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 20

Let's proceed to step 5:
20 can be fit into 149 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 3187.0
If we take 140 away from 149, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 20

Moving on to step 6:
When dividing 99 by 20, we get 4 with a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 31874.0
Subtract 80 from 99 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
If we divide 190 by 20, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 31874.9
Deduct 180 from 190 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 31874.95
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 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31874.95
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31874.95
Deduct 0 from 0 and we're left 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.

The final result is 31874.95 with a remainder of 0.0.
