557526 ÷ 90 
Let's see how many times 90 fits into 557526.

Step 1:
5 divided by 90 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 90

On to step 2:
When dividing 55 by 90, we get 0 with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 90

Moving on to step 3:
90 can be fit into 557 6 times, resulting in a remainder of 17.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 17 after subtracting 540 from 557.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 90

Advancing to step 4:
If we divide 175 by 90, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtract 90 from 175 to get 85.
Bring next digit (2) of the dividend behind the 85 and repeat the process: 852 / 90

Going ahead to step 5:
852 divided by 90 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 619.0
If we subtract 810 from 852, we get 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 90

Advancing to step 6:
When dividing 426 by 90, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 6194.0
Deduct 360 from 426 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
90 goes into 660 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 6194.7
Deduct 630 from 660 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 90, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 6194.73
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 6194.733
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 6194.733 and a remainder of 0.003.
