We divide 517466 by 90
We want to figure out the number of times 517466 can be divided by 90.

On to step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 90

Step 2:
If we divide 51 by 90, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 90

Let's proceed to step 3:
90 can be fit into 517 5 times, resulting in a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 450 away from 517, we end up with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 90

Moving on to step 4:
90 can be fit into 674 7 times, resulting in a remainder of 44.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 630 from 674 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 90

Advancing to step 5:
90 can be fit into 446 4 times, resulting in a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 574.0
If we take 360 away from 446, we end up with 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 90

Moving on to step 6:
90 can be fit into 866 9 times, resulting in a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 5749.0
If we subtract 810 from 866, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
560 divided by 90 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 5749.6
If we subtract 540 from 560, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 5749.62
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 5749.622
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 5749.622, with a leftover of 0.002.
