908370 ÷ 20 
Let's see how many times 20 fits into 908370.

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
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Going ahead to step 2:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 80 from 90 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 20

On to step 3:
If we divide 108 by 20, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 100 from 108 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 20

Going ahead to step 4:
When dividing 83 by 20, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 454.0
Deduct 80 from 83 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 20

Advancing to step 5:
20 can be fit into 37 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 4541.0
Deduct 20 from 37 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 20

Step 6:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 45418.0
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45418.5
Deduct 100 from 100 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.

Step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45418.5
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.

Going ahead to step 9:
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: 45418.5
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.

The quotient of the division is 45418.5, and the remainder is 0.0.
