Let's divide 514878 by 66
The aim is to understand the frequency of 66 in 514878.

Let's proceed to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 66

Going ahead to step 2:
The number 66 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 66

Step 3:
66 can be fit into 514 7 times, resulting in a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 462 away from 514, we end up with 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 66

Let's proceed to step 4:
528 divided by 66 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 528 from 528 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 66

Advancing to step 5:
When dividing 7 by 66, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 66

Moving on to step 6:
The number 66 fits into 78 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 7801.0
Subtract 66 from 78 to get 12.
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 7:
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: 7801.1
If we subtract 66 from 120, we get 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 8:
When dividing 540 by 66, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7801.18
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.

On to step 9:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 7801.181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 66, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 7801.1818
Subtracting 528 from 540 leaves us 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.

Going ahead to step 11:
If we divide 120 by 66, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 7801.18181
Subtract 66 from 120 to get 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 12:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 7801.181818
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.

Step 13:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7801.1818181
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 14:
When dividing 540 by 66, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 7801.18181818
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.

In conclusion, the division gives 7801.18181818 with a balance of 1.2e-08.
