867383 ÷ 66 
The aim is to understand the frequency of 66 in 867383.

On to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 66

Advancing to step 2:
66 can be fit into 86 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 66 from 86 and we're left with 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 66

On to step 3:
If we divide 207 by 66, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 198 from 207 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 66

Step 4:
If we divide 93 by 66, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 131.0
Subtracting 66 from 93 leaves us with 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 66

Advancing to step 5:
66 goes into 278 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1314.0
Deduct 264 from 278 and we're left with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 66

Advancing to step 6:
When dividing 143 by 66, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 13142.0
Subtracting 132 from 143 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
66 can be fit into 110 1 times, resulting in a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 13142.1
Deduct 66 from 110 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
440 divided by 66 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 13142.16
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
66 can be fit into 440 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 13142.166
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 13142.166, and the remainder is 0.0044.
