We're dividing 79977105 by 66 
The aim is to understand the frequency of 66 in 79977105.

Going ahead to step 1:
The number 66 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 66

Let's proceed to step 2:
66 goes into 79 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 79 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 66

Going ahead to step 3:
When dividing 139 by 66, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 132 from 139 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 66

On to step 4:
66 can be fit into 77 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Deduct 66 from 77 and we're left with 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 66

Let's proceed to step 5:
If we divide 117 by 66, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
The remainder is 51 after subtracting 66 from 117.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 66

Let's proceed to step 6:
511 divided by 66 is 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 12117.0
Deduct 462 from 511 and we're left with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 66

Going ahead to step 7:
66 goes into 490 7 times with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 121177.0
Subtract 462 from 490 to get 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 66

Let's proceed to step 8:
285 divided by 66 is 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 1211774.0
If we subtract 264 from 285, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
66 can be fit into 210 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 1211774.3
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
If we divide 120 by 66, we get 1 and a remainder of 54.
The next digit of our result is 1. 
Result so far: 1211774.31
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
540 divided by 66 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1211774.318
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 66 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1211774.3181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 66 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1211774.31818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1211774.318181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 15:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 1211774.3181818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 16:
When dividing 120 by 66, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1211774.31818181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 1211774.31818181 with a remaining 5.4e-08.
