Let's divide 526491 by 90
We want to divide 526491 by 90.

Going ahead to step 1:
5 divided by 90 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 90

On to step 2:
90 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 90

Moving on to step 3:
When dividing 526 by 90, we get 5 with a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 76 after subtracting 450 from 526.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 90

Step 4:
If we divide 764 by 90, we get 8 and a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 720 from 764 to get 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 90

Moving on to step 5:
If we divide 449 by 90, we get 4 and a remainder of 89.
Record the quotient 4 as the next digit in the result. 
Result so far: 584.0
If we subtract 360 from 449, we get 89.
Include the next digit (1) from the dividend after 89, then repeat: 891 / 90

Step 6:
90 goes into 891 9 times with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 5849.0
If we take 810 away from 891, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 7:
810 divided by 90 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 5849.9
Deduct 810 from 810 and we're left 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.

Going ahead to step 8:
90 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: 5849.9
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.

Advancing to step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5849.9
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 5849.9, with a leftover of 0.0.
