We look at the division of 839524 by 20 
We want to figure out the number of times 839524 can be divided by 20.

Moving on to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 20

Let's proceed to step 2:
If we divide 83 by 20, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 3 after subtracting 80 from 83.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 20

Going ahead to step 3:
The number 20 fits into 39 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 20 from 39 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 20

Going ahead to step 4:
195 divided by 20 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 419.0
The remainder is 15 after subtracting 180 from 195.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 20

Advancing to step 5:
If we divide 152 by 20, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 4197.0
Subtract 140 from 152 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 20

Advancing to step 6:
When dividing 124 by 20, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 41976.0
If we subtract 120 from 124, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 41976.2
Subtract 40 from 40 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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41976.2
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41976.2
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.

After the division, we end up with 41976.2 and a remainder of 0.0.
