Let's divide 428618 by 66
The aim is to understand the frequency of 66 in 428618.

Moving on to step 1:
If we divide 4 by 66, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 66

Moving on to step 2:
66 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 66

Let's proceed to step 3:
66 can be fit into 428 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 6.0
If we take 396 away from 428, we end up with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 66

Let's proceed to step 4:
66 can be fit into 326 4 times, resulting in a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 264 away from 326, we end up with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 66

Step 5:
When dividing 621 by 66, we get 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 649.0
If we take 594 away from 621, we end up with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 66

Going ahead to step 6:
66 goes into 278 4 times with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 6494.0
Subtract 264 from 278 to get 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 7:
When dividing 140 by 66, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 6494.2
If we take 132 away from 140, we end up 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.

On to step 8:
80 divided by 66 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 6494.21
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.

Moving on to step 9:
66 goes into 140 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6494.212
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 10:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 6494.2121
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.

Let's proceed to step 11:
If we divide 140 by 66, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 6494.21212
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.

Going ahead to step 12:
If we divide 80 by 66, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 6494.212121
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 13:
When dividing 140 by 66, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6494.2121212
If we subtract 132 from 140, we 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 14:
66 goes into 80 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6494.21212121
If we subtract 66 from 80, we get 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 6494.21212121, and the remainder is 1.4e-08.
