We're dividing 208214 by 66 
The aim is to understand the frequency of 66 in 208214.

Step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 66

Let's proceed to step 2:
66 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 66

Step 3:
The number 66 fits into 208 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 10 after subtracting 198 from 208.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 66

Moving on to step 4:
66 goes into 102 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 66 from 102 and we're left with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 66

Step 5:
66 goes into 361 5 times with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 315.0
If we take 330 away from 361, we end up with 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 66

Step 6:
66 can be fit into 314 4 times, resulting in a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 3154.0
Subtract 264 from 314 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.

Let's proceed to step 7:
66 goes into 500 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3154.7
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.

Let's proceed to step 8:
If we divide 380 by 66, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3154.75
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.

Going ahead to step 9:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3154.757
Subtracting 462 from 500 leaves us 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.

Going ahead to step 10:
380 divided by 66 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3154.7575
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.

Moving on to step 11:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3154.75757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
When dividing 380 by 66, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 3154.757575
If we subtract 330 from 380, we 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.

Step 13:
66 goes into 500 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3154.7575757
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.

On to step 14:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3154.75757575
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 3154.75757575, and the remainder is 5e-08.
