We're dividing 915094 by 90 
The aim is to understand the frequency of 90 in 915094.

Moving on to step 1:
9 divided by 90 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 90

On to step 2:
When dividing 91 by 90, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 90 from 91 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 90

Advancing to step 3:
90 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 90

On to step 4:
90 goes into 150 1 times with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 60 after subtracting 90 from 150.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 90

Moving on to step 5:
609 divided by 90 is 6 with a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
Subtract 540 from 609 to get 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 90

Step 6:
When dividing 694 by 90, we get 7 with a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 10167.0
If we take 630 away from 694, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 7:
The number 90 fits into 640 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 10167.7
Deduct 630 from 640 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 10167.71
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
90 goes into 100 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 10167.711
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 10167.711 with a balance of 0.001.
