We look at the division of 66396744 by 627 
The aim is to understand the frequency of 627 in 66396744.

On to step 1:
627 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 627

Step 2:
627 goes into 66 0 times with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 627

Let's proceed to step 3:
627 goes into 663 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 627 from 663, we get 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 627

Step 4:
When dividing 369 by 627, we get 0 with a remainder of 369.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 369, we get 369.
Take the next digit (6) from the dividend and append it to 369, then repeat: 3696 / 627

On to step 5:
The number 627 fits into 3696 5 times, leaving a remainder of 561.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 3135 from 3696 leaves us with 561.
Fetch the next digit (7) from the dividend, attach it to 561 and continue: 5617 / 627

On to step 6:
5617 divided by 627 is 8 with a remainder of 601.
Write down 8 as next digit of the result. 
Result so far: 1058.0
If we take 5016 away from 5617, we end up with 601.
Fetch the next digit (4) from the dividend, attach it to 601 and continue: 6014 / 627

Going ahead to step 7:
The number 627 fits into 6014 9 times, leaving a remainder of 371.
The number 9 becomes the next digit in our result. 
Result so far: 10589.0
If we subtract 5643 from 6014, we get 371.
Fetch the next digit (4) from the dividend, attach it to 371 and continue: 3714 / 627

Going ahead to step 8:
3714 divided by 627 is 5 with a remainder of 579.
Put 5 as the next digit of the answer. 
Result so far: 105895.0
Subtract 3135 from 3714 to get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 9:
When dividing 5790 by 627, we get 9 with a remainder of 147.
The number 9 becomes the next digit in our result. 
Result so far: 105895.9
Subtracting 5643 from 5790 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

On to step 10:
If we divide 1470 by 627, we get 2 and a remainder of 216.
Record the quotient 2 as the next digit in the result. 
Result so far: 105895.92
If we take 1254 away from 1470, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 11:
When dividing 2160 by 627, we get 3 with a remainder of 279.
Put 3 as the next digit of the answer. 
Result so far: 105895.923
Subtracting 1881 from 2160 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 12:
The number 627 fits into 2790 4 times, leaving a remainder of 282.
Use 4 as the next digit of our solution. 
Result so far: 105895.9234
The remainder is 282 after subtracting 2508 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 13:
The number 627 fits into 2820 4 times, leaving a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 105895.92344
If we subtract 2508 from 2820, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 105895.92344 with a remaining 0.000312.
