29970871 divided by 66 
The aim is to understand the frequency of 66 in 29970871.

Moving on to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 66

Let's proceed to step 2:
29 divided by 66 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 66

Let's proceed to step 3:
When dividing 299 by 66, we get 4 with a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 264 from 299, we get 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 66

On to step 4:
66 goes into 357 5 times with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 330 from 357 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 66

Advancing to step 5:
66 goes into 270 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
Subtract 264 from 270 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 66

Moving on to step 6:
When dividing 68 by 66, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 4541.0
Deduct 66 from 68 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 66

Let's proceed to step 7:
The number 66 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 45410.0
If we subtract 0 from 27, we get 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 66

Advancing to step 8:
66 can be fit into 271 4 times, resulting in a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 454104.0
If we take 264 away from 271, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
When dividing 70 by 66, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 454104.1
Subtracting 66 from 70 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.

On to step 10:
66 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 454104.1
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.

Step 11:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 454104.106
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 66 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 454104.106
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
If we divide 400 by 66, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 454104.10606
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
The number 66 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 454104.10606
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.

Advancing to step 15:
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: 454104.1060606
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.

Advancing to step 16:
40 divided by 66 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 454104.1060606
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.

Our division results in 454104.1060606 with a remaining 4e-08.
