839758 divided by 20 
We want to figure out the number of times 839758 can be divided by 20.

Going ahead to step 1:
8 divided by 20 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 20

Moving on to step 2:
The number 20 fits into 83 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 3 after subtracting 80 from 83.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

Moving on to step 3:
20 can be fit into 39 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 20 from 39, we get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 20

Moving on to step 4:
20 goes into 197 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 419.0
Subtract 180 from 197 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 20

Moving on to step 5:
20 can be fit into 175 8 times, resulting in a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 4198.0
If we take 160 away from 175, we end up with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 20

Let's proceed to step 6:
20 can be fit into 158 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 41987.0
If we take 140 away from 158, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 41987.9
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41987.9
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.

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: 41987.9
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 final outcome is 41987.9, with a leftover of 0.0.
