Let's divide 67423635 by 66
The aim is to understand the frequency of 66 in 67423635.

Moving on to step 1:
When dividing 6 by 66, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 66

Let's proceed to step 2:
66 goes into 67 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 66 from 67 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 66

Moving on to step 3:
14 divided by 66 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 66

Going ahead to step 4:
66 goes into 142 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 10 after subtracting 132 from 142.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 66

Advancing to step 5:
The number 66 fits into 103 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
The remainder is 37 after subtracting 66 from 103.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 66

Moving on to step 6:
The number 66 fits into 376 5 times, leaving a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 10215.0
If we take 330 away from 376, we end up with 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 66

Going ahead to step 7:
463 divided by 66 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 102157.0
The remainder is 1 after subtracting 462 from 463.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 66

Advancing to step 8:
66 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 1021570.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 66, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 1021570.2
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
When dividing 180 by 66, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 1021570.22
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 1021570.22, and the remainder is 0.048.
