We divide 899435 by 20
We're looking to find how many times 20 goes into 899435.

Moving on to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 20

Moving on to step 2:
89 divided by 20 is 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 80 away from 89, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 20

Step 3:
If we divide 99 by 20, we get 4 and a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 80 from 99 leaves us with 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 20

Moving on to step 4:
194 divided by 20 is 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 449.0
The remainder is 14 after subtracting 180 from 194.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 20

Moving on to step 5:
20 goes into 143 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 4497.0
Subtracting 140 from 143 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 20

Moving on to step 6:
35 divided by 20 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 44971.0
Deduct 20 from 35 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 20 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 44971.7
If we subtract 140 from 150, we 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.

Advancing to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 44971.75
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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44971.75
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.

On to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44971.75
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.

The final result is 44971.75 with a remainder of 0.0.
