Let's divide 783981 by 20
Our goal is to divide 783981 by 20.

Going ahead to step 1:
20 goes into 7 0 times with 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.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 20

Moving on to step 2:
The number 20 fits into 78 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 18 after subtracting 60 from 78.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 20

Let's proceed to step 3:
When dividing 183 by 20, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 180 from 183, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Going ahead to step 4:
20 goes into 39 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 391.0
Deduct 20 from 39 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 20

Let's proceed to step 5:
The number 20 fits into 198 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 3919.0
Deduct 180 from 198 and we're left with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 20

Moving on to step 6:
20 goes into 181 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 39199.0
Subtracting 180 from 181 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 20 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 39199.0
Subtracting 0 from 10 leaves us 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.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 39199.05
If we take 100 away from 100, we end up 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.

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: 39199.05
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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39199.05
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.

After the division, we end up with 39199.05 and a remainder of 0.0.
