Let's divide 611486 by 66
The aim is to understand the frequency of 66 in 611486.

Advancing to step 1:
66 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 66

Going ahead to step 2:
If we divide 61 by 66, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 66

Moving on to step 3:
If we divide 611 by 66, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 17 after subtracting 594 from 611.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 66

On to step 4:
If we divide 174 by 66, we get 2 and a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we subtract 132 from 174, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 66

Let's proceed to step 5:
The number 66 fits into 428 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 926.0
If we take 396 away from 428, we end up with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 66

On to step 6:
When dividing 326 by 66, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 9264.0
If we take 264 away from 326, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
66 can be fit into 620 9 times, resulting in a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9264.9
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 66, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 9264.93
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 9264.939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
66 can be fit into 260 3 times, resulting in a remainder of 62.
The next digit of our result is 3. 
Result so far: 9264.9393
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
When dividing 620 by 66, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9264.93939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 9264.939393
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
66 goes into 620 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 9264.9393939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
If we divide 260 by 66, we get 3 and a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 9264.93939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 9264.93939393 and a remainder of 6.2e-08.
