We divide 90919 by 55
The aim is to understand the frequency of 55 in 90919.

On to step 1:
9 divided by 55 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 55

On to step 2:
If we divide 90 by 55, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 55 from 90 and we're left with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 55

Going ahead to step 3:
55 can be fit into 359 6 times, resulting in a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 330 away from 359, we end up with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 55

Step 4:
The number 55 fits into 291 5 times, leaving a remainder of 16.
The next digit of our result is 5. 
Result so far: 165.0
Subtract 275 from 291 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 55

Step 5:
55 can be fit into 169 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 1653.0
Subtract 165 from 169 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
If we divide 40 by 55, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1653.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 1653.07
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
55 goes into 150 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1653.072
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
55 goes into 400 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 1653.0727
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 55 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 1653.07272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 55, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 1653.072727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 1653.0727272
Subtracting 110 from 150 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
55 goes into 400 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 1653.07272727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 1653.07272727 with a balance of 1.5e-08.
