781648 divided by 55 
The aim is to understand the frequency of 55 in 781648.

Going ahead to step 1:
If we divide 7 by 55, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 55

Going ahead to step 2:
If we divide 78 by 55, we get 1 and a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 55 from 78 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 55

Moving on to step 3:
231 divided by 55 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 11 after subtracting 220 from 231.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 55

Step 4:
116 divided by 55 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we take 110 away from 116, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 55

Going ahead to step 5:
When dividing 64 by 55, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1421.0
If we subtract 55 from 64, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 55

Advancing to step 6:
55 can be fit into 98 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 14211.0
Subtract 55 from 98 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
The number 55 fits into 430 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 14211.7
The remainder is 45 after subtracting 385 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
If we divide 450 by 55, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 14211.78
Deduct 440 from 450 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
55 can be fit into 100 1 times, resulting in a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 14211.781
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 14211.7818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 55 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 14211.78181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
If we divide 450 by 55, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 14211.781818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
55 can be fit into 100 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 14211.7818181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
55 goes into 450 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 14211.78181818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 14211.78181818 with a balance of 1e-08.
