57490696 ÷ 66 
The aim is to understand the frequency of 66 in 57490696.

Going ahead to step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 66

Going ahead to step 2:
If we divide 57 by 66, we get 0 and a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 66

Let's proceed to step 3:
66 can be fit into 574 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 46 after subtracting 528 from 574.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 66

On to step 4:
If we divide 469 by 66, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Deduct 462 from 469 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 66

Let's proceed to step 5:
If we divide 70 by 66, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 871.0
Subtract 66 from 70 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 66

On to step 6:
46 divided by 66 is 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 8710.0
The remainder is 46 after subtracting 0 from 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 66

Moving on to step 7:
469 divided by 66 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 87107.0
The remainder is 7 after subtracting 462 from 469.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 66

Let's proceed to step 8:
66 goes into 76 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 871071.0
Subtract 66 from 76 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 66 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 871071.1
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
340 divided by 66 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 871071.15
Deduct 330 from 340 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 66, we get 1 and a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 871071.151
If we take 66 away from 100, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
66 can be fit into 340 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 871071.1515
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
If we divide 100 by 66, we get 1 and a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 871071.15151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
340 divided by 66 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 871071.151515
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
66 goes into 100 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 871071.1515151
Subtracting 66 from 100 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 16:
If we divide 340 by 66, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 871071.15151515
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 871071.15151515 with a remainder of 1e-08.
