We look at the division of 888521 by 20 
We want to figure out the number of times 888521 can be divided by 20.

On to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 20

Step 2:
The number 20 fits into 88 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 8 after subtracting 80 from 88.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 20

On to step 3:
20 can be fit into 88 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 80 from 88 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 20

Step 4:
The number 20 fits into 85 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 444.0
If we subtract 80 from 85, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 20

Moving on to step 5:
52 divided by 20 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 4442.0
If we take 40 away from 52, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 20

Moving on to step 6:
When dividing 121 by 20, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 44426.0
If we take 120 away from 121, we end up 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.

Let's proceed to step 7:
If we divide 10 by 20, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 44426.0
If we take 0 away from 10, we end up 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.

Advancing to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 44426.05
Subtract 100 from 100 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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44426.05
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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44426.05
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 final result is 44426.05 with a remainder of 0.0.
