Let's divide 84459101 by 20
Our goal is to divide 84459101 by 20.

Step 1:
8 divided by 20 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Step 2:
20 goes into 84 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 4 after subtracting 80 from 84.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 20

Moving on to step 3:
When dividing 44 by 20, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 40 from 44 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Step 4:
If we divide 45 by 20, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 422.0
If we take 40 away from 45, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 20

Moving on to step 5:
When dividing 59 by 20, we get 2 with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 4222.0
If we take 40 away from 59, we end up with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 20

Step 6:
20 can be fit into 191 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 42229.0
The remainder is 11 after subtracting 180 from 191.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 20

Let's proceed to step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 422295.0
If we take 100 away from 110, we end up with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 20

Advancing to step 8:
The number 20 fits into 101 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 4222955.0
If we subtract 100 from 101, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4222955.0
Deduct 0 from 10 and we're left 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.

Moving on to step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4222955.05
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.

Let's proceed to step 11:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4222955.05
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.

Let's proceed to step 12:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4222955.05
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.

The quotient of the division is 4222955.05, and the remainder is 0.0.
