831240 divided by 55 
The aim is to understand the frequency of 55 in 831240.

Step 1:
8 divided by 55 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 55

Going ahead to step 2:
When dividing 83 by 55, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 55 from 83 to get 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 55

On to step 3:
55 can be fit into 281 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 275 from 281 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 55

Advancing to step 4:
The number 55 fits into 62 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 55 from 62 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 55

Advancing to step 5:
55 goes into 74 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1511.0
If we take 55 away from 74, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 55

Advancing to step 6:
55 can be fit into 190 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 15113.0
Subtract 165 from 190 to 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.

Step 7:
When dividing 250 by 55, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 15113.4
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.

Let's proceed to step 8:
300 divided by 55 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15113.45
Subtract 275 from 300 to 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.

Going ahead to step 9:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 15113.454
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:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15113.4545
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.
The next digit of our result is 4. 
Result so far: 15113.45454
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.

Let's proceed to step 12:
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: 15113.454545
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.

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: 15113.4545454
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 14:
The number 55 fits into 300 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15113.45454545
The remainder is 25 after subtracting 275 from 300.
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 15113.45454545 with a remainder of 2.5e-08.
