599089 ÷ 66 
The aim is to understand the frequency of 66 in 599089.

Going ahead to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 66

Let's proceed to step 2:
If we divide 59 by 66, we get 0 and a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 66

Moving on to step 3:
The number 66 fits into 599 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 594 from 599 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 66

Moving on to step 4:
66 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 66

On to step 5:
508 divided by 66 is 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 907.0
Subtract 462 from 508 to get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 66

On to step 6:
66 can be fit into 469 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 9077.0
If we subtract 462 from 469, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 66 fits into 70 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 9077.1
The remainder is 4 after subtracting 66 from 70.
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 8:
If we divide 40 by 66, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9077.1
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.

Moving on to step 9:
66 can be fit into 400 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 9077.106
If we take 396 away from 400, we end up 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 10:
40 divided by 66 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9077.106
If we take 0 away from 40, we end up 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:
66 goes into 400 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 9077.10606
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.

Moving on to step 12:
When dividing 40 by 66, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9077.10606
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 13:
66 goes into 400 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 9077.1060606
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.

Moving on to step 14:
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: 9077.1060606
Deduct 0 from 40 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.

In conclusion, the division gives 9077.1060606 with a balance of 4e-08.
