Let's divide 778002 by 66
The aim is to understand the frequency of 66 in 778002.

On to step 1:
7 divided by 66 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 66

Let's proceed to step 2:
66 goes into 77 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 66 from 77, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 66

Going ahead to step 3:
If we divide 118 by 66, we get 1 and a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 66 away from 118, we end up with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 66

Advancing to step 4:
If we divide 520 by 66, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 462 from 520 and we're left with 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 66

Let's proceed to step 5:
If we divide 580 by 66, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 1178.0
If we subtract 528 from 580, we get 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 66

Let's proceed to step 6:
When dividing 522 by 66, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 11787.0
Deduct 462 from 522 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.

Let's proceed to step 7:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 11787.9
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 11787.9
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.

Advancing to step 9:
When dividing 600 by 66, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 11787.909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
66 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 11787.909
If we take 0 away from 60, we end up 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.

Step 11:
66 goes into 600 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 11787.90909
Subtract 594 from 600 to get 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:
66 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 11787.90909
Subtracting 0 from 60 leaves us 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.

Let's proceed to step 13:
When dividing 600 by 66, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 11787.9090909
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.

On to step 14:
If we divide 60 by 66, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 11787.9090909
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.

Our division results in 11787.9090909 with a remaining 6e-08.
