318869 ÷ 66 
The aim is to understand the frequency of 66 in 318869.

Advancing to step 1:
3 divided by 66 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 66

Going ahead to step 2:
If we divide 31 by 66, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 66

Going ahead to step 3:
If we divide 318 by 66, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 264 from 318 and we're left with 54.
Bring next digit (8) of the dividend behind the 54 and repeat the process: 548 / 66

Moving on to step 4:
When dividing 548 by 66, we get 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 20 after subtracting 528 from 548.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 66

On to step 5:
66 goes into 206 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 483.0
The remainder is 8 after subtracting 198 from 206.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 66

Advancing to step 6:
66 goes into 89 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 4831.0
If we subtract 66 from 89, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 66, we get 3 and a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 4831.3
If we take 198 away from 230, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
If we divide 320 by 66, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4831.34
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
The number 66 fits into 560 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 4831.348
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
If we divide 320 by 66, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4831.3484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4831.34848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
When dividing 320 by 66, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4831.348484
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
66 goes into 560 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 4831.3484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
When dividing 320 by 66, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 4831.34848484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 4831.34848484 with a remaining 5.6e-08.
