Let's divide 835206 by 66
The aim is to understand the frequency of 66 in 835206.

Step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 66

Advancing to step 2:
The number 66 fits into 83 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 83 leaves us with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 66

Moving on to step 3:
The number 66 fits into 175 2 times, leaving a remainder of 43.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 132 from 175 leaves us with 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 66

Let's proceed to step 4:
66 goes into 432 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 396 from 432 to get 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 66

Advancing to step 5:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1265.0
If we take 330 away from 360, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 66

Let's proceed to step 6:
66 can be fit into 306 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 12654.0
Deduct 264 from 306 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
420 divided by 66 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12654.6
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
66 goes into 240 3 times with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 12654.63
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
If we divide 420 by 66, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 12654.636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
66 goes into 240 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12654.6363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 12654.63636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 66, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 12654.636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
420 divided by 66 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 12654.6363636
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12654.63636363
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 12654.63636363, with a leftover of 4.2e-08.
