Let's divide 643049 by 55
The aim is to understand the frequency of 55 in 643049.

On to step 1:
If we divide 6 by 55, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 55

Advancing to step 2:
If we divide 64 by 55, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 55 from 64 and we're left with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 55

Let's proceed to step 3:
55 goes into 93 1 times with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 55 from 93 and we're left with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 55

Going ahead to step 4:
55 can be fit into 380 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtracting 330 from 380 leaves us with 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 55

On to step 5:
55 goes into 504 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 1169.0
Subtracting 495 from 504 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 55

On to step 6:
When dividing 99 by 55, we get 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 11691.0
If we take 55 away from 99, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
When dividing 440 by 55, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 11691.8
Subtracting 440 from 440 leaves us 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.

Advancing to step 8:
55 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11691.8
The remainder is 0 after subtracting 0 from 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:
55 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11691.8
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.

After the division, we end up with 11691.8 and a remainder of 0.0.
