406643 divided by 55 
The aim is to understand the frequency of 55 in 406643.

Going ahead to step 1:
4 divided by 55 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 55

Let's proceed to step 2:
55 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 55

Advancing to step 3:
The number 55 fits into 406 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 385 from 406 leaves us with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 55

Going ahead to step 4:
If we divide 216 by 55, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 165 from 216 leaves us with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 55

Going ahead to step 5:
55 goes into 514 9 times with a remainder of 19.
The next digit of our result is 9. 
Result so far: 739.0
Subtracting 495 from 514 leaves us with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 55

On to step 6:
The number 55 fits into 193 3 times, leaving a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 7393.0
If we take 165 away from 193, we end up 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.

Going ahead to step 7:
280 divided by 55 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7393.5
The remainder is 5 after subtracting 275 from 280.
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 8:
When dividing 50 by 55, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7393.5
Subtract 0 from 50 to 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 9:
When dividing 500 by 55, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 7393.509
Subtracting 495 from 500 leaves us 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 10:
When dividing 50 by 55, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 7393.509
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.

Step 11:
If we divide 500 by 55, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 7393.50909
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 12:
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: 7393.50909
If we take 0 away from 50, we end up 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.

On to step 13:
When dividing 500 by 55, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 7393.5090909
Deduct 495 from 500 and we're left 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.

Going ahead to step 14:
55 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 7393.5090909
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.

Our division results in 7393.5090909 with a remaining 5e-08.
