90290 divided by 86 
We want to divide 90290 by 86.

Going ahead to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 86

Advancing to step 2:
When dividing 90 by 86, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 86 from 90.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 86

Moving on to step 3:
If we divide 42 by 86, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 42, we end up with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 86

Advancing to step 4:
86 can be fit into 429 4 times, resulting in a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 344 from 429 and we're left with 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 86

Moving on to step 5:
When dividing 850 by 86, we get 9 with a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 1049.0
If we take 774 away from 850, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 6:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 1049.8
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
86 can be fit into 720 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 1049.88
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 1049.88 with a balance of 0.032.
