972183 divided by 66 
The aim is to understand the frequency of 66 in 972183.

On to step 1:
66 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 66

Let's proceed to step 2:
66 goes into 97 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 66 from 97, we get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 66

Step 3:
66 can be fit into 312 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 264 from 312 and we're left with 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 66

Step 4:
When dividing 481 by 66, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
The remainder is 19 after subtracting 462 from 481.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 66

Moving on to step 5:
66 can be fit into 198 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1473.0
Deduct 198 from 198 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 66

On to step 6:
The number 66 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 14730.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 66 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 14730.0
Subtracting 0 from 30 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.

Step 8:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 14730.04
Deduct 264 from 300 and we're left 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.

Step 9:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 14730.045
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.

Advancing to step 10:
66 goes into 300 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 14730.0454
If we take 264 away from 300, we end up 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.

Step 11:
66 can be fit into 360 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 14730.04545
Subtract 330 from 360 to 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.

Advancing to step 12:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 14730.045454
If we subtract 264 from 300, we 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.

On to step 13:
66 goes into 360 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 14730.0454545
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.

Going ahead to step 14:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 14730.04545454
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.

After the division, we end up with 14730.04545454 and a remainder of 3.6e-08.
