Let's divide 990106 by 55
The aim is to understand the frequency of 55 in 990106.

Going ahead to step 1:
If we divide 9 by 55, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 55

Let's proceed to step 2:
55 can be fit into 99 1 times, resulting in a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 55 from 99 to get 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 55

Moving on to step 3:
55 goes into 440 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 440 from 440, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 55

Advancing to step 4:
If we divide 1 by 55, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 55

On to step 5:
10 divided by 55 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1800.0
If we take 0 away from 10, we end up with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 55

Moving on to step 6:
55 goes into 106 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 18001.0
The remainder is 51 after subtracting 55 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
510 divided by 55 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 18001.9
Deduct 495 from 510 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.

On to step 8:
When dividing 150 by 55, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 18001.92
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.

Let's proceed to step 9:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 18001.927
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.

Going ahead to step 10:
When dividing 150 by 55, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 18001.9272
Subtract 110 from 150 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.

Moving on to step 11:
When dividing 400 by 55, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 18001.92727
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.

Advancing to step 12:
150 divided by 55 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 18001.927272
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:
400 divided by 55 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 18001.9272727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
150 divided by 55 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 18001.92727272
If we subtract 110 from 150, we 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.

After the division, we end up with 18001.92727272 and a remainder of 4e-08.
