We divide 7839622 by 20
We're looking to find how many times 20 goes into 7839622.

Moving on to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Going ahead to step 2:
When dividing 78 by 20, we get 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 60 from 78, we get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 20

On 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

Let's proceed to step 4:
If we divide 39 by 20, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
The remainder is 19 after subtracting 20 from 39.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 20

Moving on to step 5:
The number 20 fits into 196 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 3919.0
Subtract 180 from 196 to get 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 20

Going ahead to step 6:
162 divided by 20 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 39198.0
Subtract 160 from 162 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 20

Step 7:
22 divided by 20 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 391981.0
If we subtract 20 from 22, we 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.

Advancing to step 8:
20 divided by 20 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 391981.1
The remainder is 0 after subtracting 20 from 20.
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 391981.1
If we take 0 away from 0, 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.

Going ahead to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 391981.1
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.

The quotient of the division is 391981.1, and the remainder is 0.0.
