We divide 77448 by 66
The aim is to understand the frequency of 66 in 77448.

On to step 1:
7 divided by 66 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 66

Advancing to step 2:
66 goes into 77 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 66 from 77 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 66

Going ahead to step 3:
If we divide 114 by 66, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 66 from 114 leaves us with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 66

Let's proceed to step 4:
If we divide 484 by 66, we get 7 and a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 462 from 484 to get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 66

On to step 5:
When dividing 228 by 66, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 1173.0
Subtracting 198 from 228 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 6:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 1173.4
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 66, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1173.45
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 1173.454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 1173.4545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 66 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1173.45454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1173.454545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 66, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 1173.4545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 1173.45454545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 1173.45454545 and a remainder of 3e-08.
