Let's divide 554572 by 66
The aim is to understand the frequency of 66 in 554572.

Going ahead to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 66

Let's proceed to step 2:
If we divide 55 by 66, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 66

Step 3:
66 goes into 554 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 528 from 554 and we're left with 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 66

Step 4:
66 can be fit into 265 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 264 from 265 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 66

Let's proceed to step 5:
When dividing 17 by 66, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 840.0
If we take 0 away from 17, we end up with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 66

Let's proceed to step 6:
172 divided by 66 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 8402.0
The remainder is 40 after subtracting 132 from 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
66 goes into 400 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8402.6
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 66 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8402.6
If we subtract 0 from 40, we 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.

Going ahead to step 9:
If we divide 400 by 66, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8402.606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
66 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8402.606
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 11:
400 divided by 66 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 8402.60606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 66, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8402.60606
If we subtract 0 from 40, we 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.

On to step 13:
If we divide 400 by 66, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 8402.6060606
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 66 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8402.6060606
Subtract 0 from 40 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.

The final outcome is 8402.6060606, with a leftover of 4e-08.
