902212 ÷ 90 
Let's see how many times 90 fits into 902212.

Moving on to step 1:
90 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 90

Let's proceed to step 2:
If we divide 90 by 90, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 90 from 90, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 90

On to step 3:
2 divided by 90 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 90

Step 4:
90 goes into 22 0 times with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 90

Advancing to step 5:
90 can be fit into 221 2 times, resulting in a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 1002.0
If we take 180 away from 221, we end up with 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 90

Advancing to step 6:
90 can be fit into 412 4 times, resulting in a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 10024.0
The remainder is 52 after subtracting 360 from 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
The number 90 fits into 520 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 10024.5
If we subtract 450 from 520, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 10024.57
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 10024.577
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 10024.577 with a remaining 0.007.
