We divide 12166202 by 660
The aim is to understand the frequency of 660 in 12166202.

Moving on to step 1:
660 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 660

Moving on to step 2:
The number 660 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 660

Let's proceed to step 3:
660 can be fit into 121 0 times, resulting in a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 121 leaves us with 121.
Take the next digit (6) from the dividend and append it to 121, then repeat: 1216 / 660

Let's proceed to step 4:
660 goes into 1216 1 times with a remainder of 556.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 660 from 1216, we get 556.
Append the next digit (6) from the dividend to 556 and continue with: 5566 / 660

Moving on to step 5:
When dividing 5566 by 660, we get 8 with a remainder of 286.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 5280 from 5566 and we're left with 286.
Bring next digit (2) of the dividend behind the 286 and repeat the process: 2862 / 660

Moving on to step 6:
The number 660 fits into 2862 4 times, leaving a remainder of 222.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we subtract 2640 from 2862, we get 222.
Bring next digit (0) of the dividend behind the 222 and repeat the process: 2220 / 660

On to step 7:
If we divide 2220 by 660, we get 3 and a remainder of 240.
The number 3 becomes the next digit in our result. 
Result so far: 1843.0
Subtracting 1980 from 2220 leaves us with 240.
Append the next digit (2) from the dividend to 240 and continue with: 2402 / 660

Let's proceed to step 8:
660 can be fit into 2402 3 times, resulting in a remainder of 422.
The number 3 becomes the next digit in our result. 
Result so far: 18433.0
Deduct 1980 from 2402 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 9:
4220 divided by 660 is 6 with a remainder of 260.
Record the quotient 6 as the next digit in the result. 
Result so far: 18433.6
Subtracting 3960 from 4220 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
If we divide 2600 by 660, we get 3 and a remainder of 620.
The next digit of our result is 3. 
Result so far: 18433.63
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 11:
6200 divided by 660 is 9 with a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 18433.639
If we subtract 5940 from 6200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
660 can be fit into 2600 3 times, resulting in a remainder of 620.
The next digit of our result is 3. 
Result so far: 18433.6393
Subtract 1980 from 2600 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 13:
When dividing 6200 by 660, we get 9 with a remainder of 260.
The next digit of our result is 9. 
Result so far: 18433.63939
Subtract 5940 from 6200 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
2600 divided by 660 is 3 with a remainder of 620.
The number 3 becomes the next digit in our result. 
Result so far: 18433.639393
If we take 1980 away from 2600, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 15:
The number 660 fits into 6200 9 times, leaving a remainder of 260.
Use 9 as the next digit of our solution. 
Result so far: 18433.6393939
Subtracting 5940 from 6200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
If we divide 2600 by 660, we get 3 and a remainder of 620.
The number 3 becomes the next digit in our result. 
Result so far: 18433.63939393
Subtracting 1980 from 2600 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Our division results in 18433.63939393 with a remaining 6.2e-07.
