We divide 906449 by 20
We want to figure out the number of times 906449 can be divided by 20.

Step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 20

Step 2:
20 goes into 90 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 80 away from 90, we end up with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 20

Let's proceed to step 3:
When dividing 106 by 20, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 45.0
The remainder is 6 after subtracting 100 from 106.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 20

Let's proceed to step 4:
The number 20 fits into 64 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 453.0
Deduct 60 from 64 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

Step 5:
44 divided by 20 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 4532.0
The remainder is 4 after subtracting 40 from 44.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 20

Advancing to step 6:
When dividing 49 by 20, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 45322.0
The remainder is 9 after subtracting 40 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 45322.4
Subtract 80 from 90 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 45322.45
The remainder is 0 after subtracting 100 from 100.
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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45322.45
The remainder is 0 after subtracting 0 from 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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45322.45
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.

Our division results in 45322.45 with a remaining 0.0.
