We look at the division of 971603 by 55 
The aim is to understand the frequency of 55 in 971603.

On to step 1:
The number 55 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 55

Going ahead to step 2:
55 can be fit into 97 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 42 after subtracting 55 from 97.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 55

Let's proceed to step 3:
The number 55 fits into 421 7 times, leaving a remainder of 36.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 385 from 421 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 55

Let's proceed to step 4:
55 can be fit into 366 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 176.0
The remainder is 36 after subtracting 330 from 366.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 55

Step 5:
55 can be fit into 360 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 1766.0
Deduct 330 from 360 and we're left with 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 55

On to step 6:
303 divided by 55 is 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 17665.0
Deduct 275 from 303 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
55 can be fit into 280 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 17665.5
If we take 275 away from 280, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 17665.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
500 divided by 55 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 17665.509
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 17665.509
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 55, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 17665.50909
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
When dividing 50 by 55, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 17665.50909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
55 goes into 500 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 17665.5090909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
50 divided by 55 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 17665.5090909
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 17665.5090909 and a remainder of 5e-08.
