Let's divide 499977 by 66
The aim is to understand the frequency of 66 in 499977.

Step 1:
If we divide 4 by 66, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 66

Let's proceed to step 2:
When dividing 49 by 66, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 66

Advancing to step 3:
When dividing 499 by 66, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 462 from 499 leaves us with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 66

Step 4:
379 divided by 66 is 5 with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we take 330 away from 379, we end up with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 66

Step 5:
66 goes into 497 7 times with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 757.0
The remainder is 35 after subtracting 462 from 497.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 66

Going ahead to step 6:
66 can be fit into 357 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 7575.0
If we take 330 away from 357, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
The number 66 fits into 270 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7575.4
If we take 264 away from 270, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 7575.4
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 66, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 7575.409
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
66 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7575.409
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
66 goes into 600 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 7575.40909
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
When dividing 60 by 66, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 7575.40909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
The number 66 fits into 600 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 7575.4090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
When dividing 60 by 66, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7575.4090909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 7575.4090909, with a leftover of 6e-08.
