404987 ÷ 55 
The aim is to understand the frequency of 55 in 404987.

Advancing to step 1:
55 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 55

Going ahead to step 2:
55 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 55

Moving on to step 3:
If we divide 404 by 55, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 385 from 404 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 55

Moving on to step 4:
199 divided by 55 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 34 after subtracting 165 from 199.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 55

Moving on to step 5:
348 divided by 55 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 736.0
Subtract 330 from 348 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 55

Let's proceed to step 6:
When dividing 187 by 55, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 7363.0
If we subtract 165 from 187, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
The number 55 fits into 220 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 7363.4
If we subtract 220 from 220, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 55, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7363.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 55, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7363.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 7363.4, and the remainder is 0.0.
