643767 ÷ 55 
The aim is to understand the frequency of 55 in 643767.

Advancing to step 1:
When dividing 6 by 55, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 55

Advancing to step 2:
When dividing 64 by 55, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 55 from 64 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 55

Moving on to step 3:
If we divide 93 by 55, we get 1 and a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 55 from 93 and we're left with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 55

Let's proceed to step 4:
387 divided by 55 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 385 from 387 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 55

Step 5:
If we divide 26 by 55, we get 0 and a remainder of 26.
The next digit of our result is 0. 
Result so far: 1170.0
If we take 0 away from 26, we end up with 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 55

On to step 6:
55 goes into 267 4 times with a remainder of 47.
The next digit of our result is 4. 
Result so far: 11704.0
Subtract 220 from 267 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
When dividing 470 by 55, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 11704.8
Subtracting 440 from 470 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 55 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11704.85
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
55 can be fit into 250 4 times, resulting in a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 11704.854
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 55, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11704.8545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 11704.85454
Subtracting 220 from 250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
55 goes into 300 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11704.854545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
55 goes into 250 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 11704.8545454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11704.85454545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 11704.85454545 with a remainder of 2.5e-08.
