Let's divide 278504 by 66
The aim is to understand the frequency of 66 in 278504.

Going ahead to step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 66

Going ahead to step 2:
27 divided by 66 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 66

Let's proceed to step 3:
66 can be fit into 278 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 264 from 278 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 66

Going ahead to step 4:
145 divided by 66 is 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 13 after subtracting 132 from 145.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 66

Step 5:
130 divided by 66 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 421.0
If we take 66 away from 130, we end up with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 66

Going ahead to step 6:
644 divided by 66 is 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 4219.0
If we take 594 away from 644, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 4219.7
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
66 goes into 380 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4219.75
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 4219.757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 4219.7575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 4219.75757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
If we divide 380 by 66, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4219.757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 4219.7575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4219.75757575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 4219.75757575, and the remainder is 5e-08.
