We look at the division of 402614 by 66 
The aim is to understand the frequency of 66 in 402614.

Advancing to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 66

Step 2:
66 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 66

On to step 3:
66 goes into 402 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 396 from 402 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 66

Going ahead to step 4:
66 can be fit into 66 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtracting 66 from 66 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 66

On to step 5:
66 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 610.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 66

Advancing to step 6:
66 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 6100.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6100.2
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 66, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6100.21
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 6100.212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
66 can be fit into 80 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 6100.2121
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
When dividing 140 by 66, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6100.21212
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 6100.212121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 6100.2121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
When dividing 80 by 66, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 6100.21212121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 6100.21212121, and the remainder is 1.4e-08.
