42227097 divided by 90 
The aim is to understand the frequency of 90 in 42227097.

On to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 90

Advancing to step 2:
When dividing 42 by 90, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 90

On to step 3:
90 can be fit into 422 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 360 from 422, we get 62.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 90

On to step 4:
90 goes into 622 6 times with a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 540 from 622 and we're left with 82.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 90

Moving on to step 5:
90 goes into 827 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 469.0
Deduct 810 from 827 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 90

Going ahead to step 6:
If we divide 170 by 90, we get 1 and a remainder of 80.
The next digit of our result is 1. 
Result so far: 4691.0
The remainder is 80 after subtracting 90 from 170.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 90

Advancing to step 7:
90 can be fit into 809 8 times, resulting in a remainder of 89.
The next digit of our result is 8. 
Result so far: 46918.0
Subtract 720 from 809 to get 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 90

Advancing to step 8:
90 can be fit into 897 9 times, resulting in a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 469189.0
Subtract 810 from 897 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 9:
The number 90 fits into 870 9 times, leaving a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 469189.9
If we take 810 away from 870, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
90 goes into 600 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 469189.96
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
If we divide 600 by 90, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 469189.966
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 469189.966 with a balance of 0.006.
