Let's divide 57698275 by 90
The aim is to understand the frequency of 90 in 57698275.

Advancing to step 1:
90 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 90

Step 2:
57 divided by 90 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 90

Moving on to step 3:
576 divided by 90 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 540 away from 576, we end up with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 90

Going ahead to step 4:
90 can be fit into 369 4 times, resulting in a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we take 360 away from 369, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 90

Advancing to step 5:
If we divide 98 by 90, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 641.0
If we take 90 away from 98, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 90

On to step 6:
If we divide 82 by 90, we get 0 and a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 6410.0
Deduct 0 from 82 and we're left with 82.
Take the next digit (7) from the dividend and append it to 82, then repeat: 827 / 90

Going ahead to step 7:
827 divided by 90 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 64109.0
Subtract 810 from 827 to get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 90

On to step 8:
If we divide 175 by 90, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 641091.0
The remainder is 85 after subtracting 90 from 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
The number 90 fits into 850 9 times, leaving a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 641091.9
Subtract 810 from 850 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 90, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 641091.94
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
90 goes into 400 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 641091.944
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 641091.944 with a balance of 0.004.
