We're dividing 931053 by 66 
The aim is to understand the frequency of 66 in 931053.

Step 1:
When dividing 9 by 66, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 66

Advancing to step 2:
The number 66 fits into 93 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 66 from 93 leaves us with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 66

Step 3:
The number 66 fits into 271 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 264 from 271 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 66

Moving on to step 4:
66 can be fit into 70 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 141.0
Deduct 66 from 70 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 66

Advancing to step 5:
The number 66 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 1410.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 66

Moving on to step 6:
The number 66 fits into 453 6 times, leaving a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 14106.0
If we take 396 away from 453, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
66 can be fit into 570 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 14106.8
Deduct 528 from 570 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.

Going ahead to step 8:
If we divide 420 by 66, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 14106.86
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.

Going ahead to step 9:
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: 14106.863
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.

Step 10:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 14106.8636
If we subtract 396 from 420, we 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 11:
66 goes into 240 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 14106.86363
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.

On to step 12:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 14106.863636
Subtracting 396 from 420 leaves us 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 13:
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: 14106.8636363
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.

Going ahead to step 14:
If we divide 420 by 66, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 14106.86363636
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.

The quotient of the division is 14106.86363636, and the remainder is 2.4e-08.
