We're dividing 16662477 by 660 
The aim is to understand the frequency of 660 in 16662477.

Step 1:
If we divide 1 by 660, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 660

Advancing to step 2:
16 divided by 660 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 660

Going ahead to step 3:
166 divided by 660 is 0 with a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Include the next digit (6) from the dividend after 166, then repeat: 1666 / 660

Advancing to step 4:
1666 divided by 660 is 2 with a remainder of 346.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1320 from 1666 to get 346.
Include the next digit (2) from the dividend after 346, then repeat: 3462 / 660

Let's proceed to step 5:
660 goes into 3462 5 times with a remainder of 162.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 3300 away from 3462, we end up with 162.
Grab the next digit (4) from the dividend, add it to 162, then carry on: 1624 / 660

Let's proceed to step 6:
When dividing 1624 by 660, we get 2 with a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Deduct 1320 from 1624 and we're left with 304.
Include the next digit (7) from the dividend after 304, then repeat: 3047 / 660

Let's proceed to step 7:
The number 660 fits into 3047 4 times, leaving a remainder of 407.
Write down 4 as next digit of the result. 
Result so far: 2524.0
The remainder is 407 after subtracting 2640 from 3047.
Take the next digit (7) from the dividend and append it to 407, then repeat: 4077 / 660

Going ahead to step 8:
660 goes into 4077 6 times with a remainder of 117.
The number 6 becomes the next digit in our result. 
Result so far: 25246.0
If we take 3960 away from 4077, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
660 goes into 1170 1 times with a remainder of 510.
Write down 1 as next digit of the result. 
Result so far: 25246.1
If we subtract 660 from 1170, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 10:
5100 divided by 660 is 7 with a remainder of 480.
Record the quotient 7 as the next digit in the result. 
Result so far: 25246.17
Subtracting 4620 from 5100 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 11:
If we divide 4800 by 660, we get 7 and a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 25246.177
The remainder is 180 after subtracting 4620 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The quotient of the division is 25246.177, and the remainder is 0.018.
