We look at the division of 872460 by 90 
We're looking to find how many times 90 goes into 872460.

Going ahead to step 1:
The number 90 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 90

On to step 2:
90 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 90

Moving on to step 3:
When dividing 872 by 90, we get 9 with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 810 from 872 leaves us with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 90

Let's proceed to step 4:
624 divided by 90 is 6 with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 540 from 624, we get 84.
Take the next digit (6) from the dividend and append it to 84, then repeat: 846 / 90

Going ahead to step 5:
90 goes into 846 9 times with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 969.0
Subtract 810 from 846 to get 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 90

On to step 6:
90 can be fit into 360 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 9694.0
Subtract 360 from 360 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.

On to step 7:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9694.0
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.

Step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 9694.0
Subtracting 0 from 0 leaves us 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 9694.0, with a leftover of 0.0.
