525485 divided by 90 
Let's see how many times 90 fits into 525485.

Advancing to step 1:
If we divide 5 by 90, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 90

Step 2:
If we divide 52 by 90, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 90

Going ahead to step 3:
90 goes into 525 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 450 from 525 and we're left with 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 90

Step 4:
90 can be fit into 754 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtracting 720 from 754 leaves us with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 90

Going ahead to step 5:
If we divide 348 by 90, we get 3 and a remainder of 78.
The next digit of our result is 3. 
Result so far: 583.0
Deduct 270 from 348 and we're left with 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 90

Step 6:
785 divided by 90 is 8 with a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 5838.0
If we subtract 720 from 785, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
650 divided by 90 is 7 with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 5838.7
The remainder is 20 after subtracting 630 from 650.
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 8:
200 divided by 90 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 5838.72
Subtracting 180 from 200 leaves us with 20.
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:
90 goes into 200 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 5838.722
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 5838.722 with a balance of 0.002.
