We're dividing 55788286 by 660 
The aim is to understand the frequency of 660 in 55788286.

Advancing to step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 660

Step 2:
When dividing 55 by 660, we get 0 with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 660

Moving on to step 3:
If we divide 557 by 660, we get 0 and a remainder of 557.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 557 leaves us with 557.
Append the next digit (8) from the dividend to 557 and continue with: 5578 / 660

On to step 4:
660 goes into 5578 8 times with a remainder of 298.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 5280 from 5578 and we're left with 298.
Append the next digit (8) from the dividend to 298 and continue with: 2988 / 660

Advancing to step 5:
If we divide 2988 by 660, we get 4 and a remainder of 348.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 2640 from 2988 leaves us with 348.
Fetch the next digit (2) from the dividend, attach it to 348 and continue: 3482 / 660

On to step 6:
660 can be fit into 3482 5 times, resulting in a remainder of 182.
Use 5 as the next digit of our solution. 
Result so far: 845.0
If we subtract 3300 from 3482, we get 182.
Bring next digit (8) of the dividend behind the 182 and repeat the process: 1828 / 660

Step 7:
When dividing 1828 by 660, we get 2 with a remainder of 508.
Put 2 as the next digit of the answer. 
Result so far: 8452.0
Subtract 1320 from 1828 to get 508.
Bring next digit (6) of the dividend behind the 508 and repeat the process: 5086 / 660

Moving on to step 8:
660 goes into 5086 7 times with a remainder of 466.
Write down 7 as next digit of the result. 
Result so far: 84527.0
Deduct 4620 from 5086 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 9:
4660 divided by 660 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 84527.7
Subtract 4620 from 4660 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 660 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 84527.7
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
When dividing 4000 by 660, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 84527.706
Subtract 3960 from 4000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
The number 660 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 84527.706
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
When dividing 4000 by 660, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 84527.70606
Subtract 3960 from 4000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 660 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 84527.70606
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
The number 660 fits into 4000 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 84527.7060606
Deduct 3960 from 4000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
When dividing 400 by 660, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 84527.7060606
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 84527.7060606 with a balance of 4e-07.
