We divide 783424 by 20
Our goal is to divide 783424 by 20.

Step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Moving on to step 2:
If we divide 78 by 20, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 60 from 78 leaves us with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 20

Moving on to step 3:
When dividing 183 by 20, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtracting 180 from 183 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 20

Advancing to step 4:
20 can be fit into 34 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 391.0
Subtracting 20 from 34 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Step 5:
20 can be fit into 142 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 3917.0
Subtracting 140 from 142 leaves us with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 20

Going ahead to step 6:
If we divide 24 by 20, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 39171.0
If we subtract 20 from 24, 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.

Moving on to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 39171.2
The remainder is 0 after subtracting 40 from 40.
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39171.2
Subtract 0 from 0 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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39171.2
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.

The final result is 39171.2 with a remainder of 0.0.
