Let's divide 85558370 by 90
We're looking to find how many times 90 goes into 85558370.

Moving on to step 1:
If we divide 8 by 90, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 90

Moving on to step 2:
90 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 90

Going ahead to step 3:
If we divide 855 by 90, we get 9 and a remainder of 45.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 810 from 855 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 90

Advancing to step 4:
455 divided by 90 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we take 450 away from 455, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 90

Step 5:
If we divide 58 by 90, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 950.0
The remainder is 58 after subtracting 0 from 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 90

Moving on to step 6:
If we divide 583 by 90, we get 6 and a remainder of 43.
The next digit of our result is 6. 
Result so far: 9506.0
The remainder is 43 after subtracting 540 from 583.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 90

Let's proceed to step 7:
The number 90 fits into 437 4 times, leaving a remainder of 77.
Put 4 as the next digit of the answer. 
Result so far: 95064.0
Deduct 360 from 437 and we're left with 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 90

Step 8:
90 goes into 770 8 times with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 950648.0
Subtracting 720 from 770 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 950648.5
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 90, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 950648.55
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 950648.55 with a balance of 0.05.
