We divide 903498 by 20
We're looking to find how many times 20 goes into 903498.

Going ahead to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Step 2:
20 goes into 90 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 10 after subtracting 80 from 90.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 20

Step 3:
The number 20 fits into 103 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 100 away from 103, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 20

Step 4:
The number 20 fits into 34 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 451.0
Deduct 20 from 34 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 20

Going ahead to step 5:
149 divided by 20 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 4517.0
Deduct 140 from 149 and we're left with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 20

Step 6:
98 divided by 20 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 45174.0
If we take 80 away from 98, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
20 goes into 180 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 45174.9
If we take 180 away from 180, 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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45174.9
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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45174.9
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.

Our division results in 45174.9 with a remaining 0.0.
