We're dividing 830036 by 66 
The aim is to understand the frequency of 66 in 830036.

Let's proceed to step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 66

Moving on to step 2:
When dividing 83 by 66, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 83 to get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 66

On to step 3:
66 goes into 170 2 times with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 132 away from 170, we end up with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 66

Advancing to step 4:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtracting 330 from 380 leaves us with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 66

Advancing to step 5:
503 divided by 66 is 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 1257.0
If we subtract 462 from 503, we get 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 66

Step 6:
The number 66 fits into 416 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 12576.0
The remainder is 20 after subtracting 396 from 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 66 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 12576.3
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 66 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12576.3
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 12576.303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 66 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 12576.303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
200 divided by 66 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 12576.30303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
If we divide 20 by 66, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12576.30303
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 12576.3030303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
66 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12576.3030303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12576.3030303, with a leftover of 2e-08.
