757030 ÷ 66 
The aim is to understand the frequency of 66 in 757030.

On to step 1:
If we divide 7 by 66, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 66

Let's proceed to step 2:
75 divided by 66 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 66 from 75 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 66

Step 3:
If we divide 97 by 66, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 11.0
If we take 66 away from 97, we end up with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 66

Going ahead to step 4:
310 divided by 66 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 114.0
Subtract 264 from 310 to get 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 66

Moving on to step 5:
463 divided by 66 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1147.0
If we subtract 462 from 463, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 66

Let's proceed to step 6:
If we divide 10 by 66, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 11470.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 7:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 11470.1
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
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: 11470.15
Subtract 330 from 340 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.

On to step 9:
66 can be fit into 100 1 times, resulting in a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 11470.151
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.

Let's proceed to step 10:
66 goes into 340 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11470.1515
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.

On to step 11:
66 goes into 100 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 11470.15151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
When dividing 340 by 66, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 11470.151515
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.

Step 13:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 11470.1515151
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.

On to step 14:
66 goes into 340 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11470.15151515
Subtract 330 from 340 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.

After the division, we end up with 11470.15151515 and a remainder of 1e-08.
