743630 divided by 66 
The aim is to understand the frequency of 66 in 743630.

Advancing to step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 66

Moving on to step 2:
66 can be fit into 74 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 66 from 74.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 66

Step 3:
66 can be fit into 83 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 66 from 83, we get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 66

Advancing to step 4:
66 goes into 176 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtract 132 from 176 to get 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 66

On to step 5:
The number 66 fits into 443 6 times, leaving a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
The remainder is 47 after subtracting 396 from 443.
Append the next digit (0) from the dividend to 47 and continue with: 470 / 66

Let's proceed to step 6:
66 goes into 470 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 11267.0
If we subtract 462 from 470, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
If we divide 80 by 66, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 11267.1
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 11267.12
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
80 divided by 66 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11267.121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11267.1212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 66, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 11267.12121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
140 divided by 66 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 11267.121212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
If we divide 80 by 66, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 11267.1212121
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 11267.12121212
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 11267.12121212 with a remainder of 8e-09.
