We divide 770180 by 66
The aim is to understand the frequency of 66 in 770180.

Moving on to step 1:
When dividing 7 by 66, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 66

Going ahead to step 2:
77 divided by 66 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 11 after subtracting 66 from 77.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 66

Step 3:
66 can be fit into 110 1 times, resulting in a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 66 from 110, we get 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 66

Step 4:
66 goes into 441 6 times with a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 396 from 441, we get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 66

Step 5:
66 can be fit into 458 6 times, resulting in a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
Deduct 396 from 458 and we're left with 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 66

On to step 6:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 11669.0
If we subtract 594 from 620, we 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.

On to step 7:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 11669.3
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.

Moving on to step 8:
66 goes into 620 9 times with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 11669.39
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.

Advancing to step 9:
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: 11669.393
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.

Going ahead to step 10:
620 divided by 66 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 11669.3939
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.

On to step 11:
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: 11669.39393
Subtracting 198 from 260 leaves us 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 12:
620 divided by 66 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 11669.393939
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.

Step 13:
If we divide 260 by 66, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 11669.3939393
If we subtract 198 from 260, we 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.

Moving on to step 14:
If we divide 620 by 66, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 11669.39393939
If we subtract 594 from 620, we 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.

After the division, we end up with 11669.39393939 and a remainder of 2.6e-08.
