We're dividing 847862 by 20 
Our goal is to divide 847862 by 20.

Going ahead to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 20

Going ahead to step 2:
If we divide 84 by 20, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 80 away from 84, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Step 3:
The number 20 fits into 47 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 40 from 47 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 20

Moving on to step 4:
The number 20 fits into 78 3 times, leaving a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Deduct 60 from 78 and we're left with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 20

Going ahead to step 5:
20 can be fit into 186 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4239.0
If we subtract 180 from 186, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 20

Going ahead to step 6:
The number 20 fits into 62 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 42393.0
Subtract 60 from 62 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 42393.1
Subtracting 20 from 20 leaves us 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 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 42393.1
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42393.1
Subtracting 0 from 0 leaves us 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 quotient of the division is 42393.1, and the remainder is 0.0.
