939501 ÷ 20 
Our goal is to divide 939501 by 20.

Going ahead to step 1:
If we divide 9 by 20, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 20

Moving on to step 2:
20 can be fit into 93 4 times, resulting in a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 80 from 93 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 20

Let's proceed to step 3:
If we divide 139 by 20, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 120 from 139, we get 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

On to step 4:
20 can be fit into 195 9 times, resulting in a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 469.0
If we take 180 away from 195, we end up with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 20

Going ahead to step 5:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 4697.0
Deduct 140 from 150 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 20

Advancing to step 6:
If we divide 101 by 20, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 46975.0
The remainder is 1 after subtracting 100 from 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 46975.0
If we subtract 0 from 10, we 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.

Moving on to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 46975.05
Deduct 100 from 100 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.

Moving on to step 9:
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: 46975.05
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.

Advancing to step 10:
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: 46975.05
The remainder is 0 after subtracting 0 from 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 quotient of the division is 46975.05, and the remainder is 0.0.
