980947 ÷ 660 
The aim is to understand the frequency of 660 in 980947.

Going ahead to step 1:
660 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 660

Moving on to step 2:
98 divided by 660 is 0 with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 660

Let's proceed to step 3:
The number 660 fits into 980 1 times, leaving a remainder of 320.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 660 from 980, we get 320.
Fetch the next digit (9) from the dividend, attach it to 320 and continue: 3209 / 660

On to step 4:
660 can be fit into 3209 4 times, resulting in a remainder of 569.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2640 from 3209 to get 569.
Take the next digit (4) from the dividend and append it to 569, then repeat: 5694 / 660

Going ahead to step 5:
660 can be fit into 5694 8 times, resulting in a remainder of 414.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we take 5280 away from 5694, we end up with 414.
Fetch the next digit (7) from the dividend, attach it to 414 and continue: 4147 / 660

Let's proceed to step 6:
4147 divided by 660 is 6 with a remainder of 187.
Record the quotient 6 as the next digit in the result. 
Result so far: 1486.0
If we subtract 3960 from 4147, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 7:
660 can be fit into 1870 2 times, resulting in a remainder of 550.
Use 2 as the next digit of our solution. 
Result so far: 1486.2
Subtracting 1320 from 1870 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 8:
When dividing 5500 by 660, we get 8 with a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 1486.28
If we subtract 5280 from 5500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 9:
If we divide 2200 by 660, we get 3 and a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 1486.283
If we subtract 1980 from 2200, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
660 can be fit into 2200 3 times, resulting in a remainder of 220.
Put 3 as the next digit of the answer. 
Result so far: 1486.2833
Deduct 1980 from 2200 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The quotient of the division is 1486.2833, and the remainder is 0.0022.
