902287 ÷ 20 
Let's see how many times 20 fits into 902287.

Advancing to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the 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.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 10 after subtracting 80 from 90.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 20

On to step 3:
102 divided by 20 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 2 after subtracting 100 from 102.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 20

Advancing to step 4:
20 can be fit into 22 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 451.0
Subtract 20 from 22 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 20

Moving on to step 5:
28 divided by 20 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 4511.0
Subtracting 20 from 28 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 20

Going ahead to step 6:
If we divide 87 by 20, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 45114.0
Deduct 80 from 87 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 20, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 45114.3
Subtract 60 from 70 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.

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 45114.35
If we subtract 100 from 100, 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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 45114.35
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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45114.35
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 final outcome is 45114.35, with a leftover of 0.0.
