Let's divide 47634622 by 90
The aim is to understand the frequency of 90 in 47634622.

Step 1:
4 divided by 90 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 90

On to step 2:
If we divide 47 by 90, we get 0 and a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 90

Let's proceed to step 3:
If we divide 476 by 90, we get 5 and a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 450 from 476, we get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 90

Advancing to step 4:
The number 90 fits into 263 2 times, leaving a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 83 after subtracting 180 from 263.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 90

Step 5:
When dividing 834 by 90, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
If we take 810 away from 834, we end up with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 90

Advancing to step 6:
246 divided by 90 is 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 5292.0
Deduct 180 from 246 and we're left with 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 90

Advancing to step 7:
When dividing 662 by 90, we get 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 52927.0
If we subtract 630 from 662, we get 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 90

Going ahead to step 8:
322 divided by 90 is 3 with a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 529273.0
Subtracting 270 from 322 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
520 divided by 90 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 529273.5
If we subtract 450 from 520, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
When dividing 700 by 90, we get 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 529273.57
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 529273.577
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 529273.577 with a balance of 0.007.
