We're dividing 9153476 by 90 
The aim is to understand the frequency of 90 in 9153476.

Let's proceed to step 1:
90 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 90

Step 2:
When dividing 91 by 90, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 90 from 91 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 90

Let's proceed to step 3:
90 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 15, we end up with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 90

Let's proceed to step 4:
When dividing 153 by 90, we get 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
The remainder is 63 after subtracting 90 from 153.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 90

On to step 5:
90 can be fit into 634 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 1017.0
Deduct 630 from 634 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 90

Advancing to step 6:
90 goes into 47 0 times with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 10170.0
If we subtract 0 from 47, we get 47.
Append the next digit (6) from the dividend to 47 and continue with: 476 / 90

Going ahead to step 7:
476 divided by 90 is 5 with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 101705.0
If we subtract 450 from 476, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
90 can be fit into 260 2 times, resulting in a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 101705.2
If we take 180 away from 260, we end up 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 9:
90 goes into 800 8 times with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 101705.28
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.

On to step 10:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 101705.288
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.

Our division results in 101705.288 with a remaining 0.008.
