We divide 86468354 by 90
We want to figure out the number of times 86468354 can be divided by 90.

Moving on to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 90

Going ahead to step 2:
90 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 90

On to step 3:
864 divided by 90 is 9 with a remainder of 54.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 810 from 864, we get 54.
Append the next digit (6) from the dividend to 54 and continue with: 546 / 90

Let's proceed to step 4:
90 goes into 546 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtract 540 from 546 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 90

On to step 5:
68 divided by 90 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 960.0
Subtract 0 from 68 to get 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 90

Step 6:
The number 90 fits into 683 7 times, leaving a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 9607.0
Subtract 630 from 683 to get 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 90

Moving on to step 7:
When dividing 535 by 90, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 96075.0
If we subtract 450 from 535, we get 85.
Bring next digit (4) of the dividend behind the 85 and repeat the process: 854 / 90

On to step 8:
When dividing 854 by 90, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 960759.0
If we subtract 810 from 854, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
90 can be fit into 440 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 960759.4
The remainder is 80 after subtracting 360 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 960759.48
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 90, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 960759.488
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 960759.488 with a balance of 0.008.
