We're dividing 900622 by 20 
We want to figure out the number of times 900622 can be divided by 20.

Step 1:
The number 20 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 20

Advancing to step 2:
20 goes into 90 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 80 from 90, we get 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 20

Going ahead to step 3:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 100 from 100 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 20

Advancing to step 4:
6 divided by 20 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 450.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 20

Going ahead to step 5:
62 divided by 20 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 4503.0
If we subtract 60 from 62, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 20

On to step 6:
20 can be fit into 22 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 45031.0
The remainder is 2 after subtracting 20 from 22.
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 7:
If we divide 20 by 20, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 45031.1
Subtract 20 from 20 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.

Going ahead to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45031.1
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45031.1
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 final outcome is 45031.1, with a leftover of 0.0.
