Let's divide 599207 by 66
The aim is to understand the frequency of 66 in 599207.

Advancing to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 66

Let's proceed to step 2:
66 can be fit into 59 0 times, resulting in a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 66

Advancing to step 3:
66 can be fit into 599 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 594 from 599, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 66

Let's proceed to step 4:
66 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 52 to get 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 66

Let's proceed to step 5:
520 divided by 66 is 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 907.0
The remainder is 58 after subtracting 462 from 520.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 66

Moving on to step 6:
66 goes into 587 8 times with a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 9078.0
If we take 528 away from 587, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
If we divide 590 by 66, we get 8 and a remainder of 62.
The next digit of our result is 8. 
Result so far: 9078.8
Subtracting 528 from 590 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 9078.89
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
When dividing 260 by 66, we get 3 with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 9078.893
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
620 divided by 66 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9078.8939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
260 divided by 66 is 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 9078.89393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9078.893939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 9078.8939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 14:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9078.89393939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 9078.89393939 and a remainder of 2.6e-08.
