26981427 ÷ 660 
The aim is to understand the frequency of 660 in 26981427.

On to step 1:
660 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 660

Going ahead to step 2:
660 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 660

Advancing to step 3:
660 can be fit into 269 0 times, resulting in a remainder of 269.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 269 to get 269.
Bring next digit (8) of the dividend behind the 269 and repeat the process: 2698 / 660

On to step 4:
2698 divided by 660 is 4 with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2640 from 2698, we get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 660

Advancing to step 5:
660 goes into 581 0 times with a remainder of 581.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 581, we get 581.
Take the next digit (4) from the dividend and append it to 581, then repeat: 5814 / 660

Going ahead to step 6:
660 goes into 5814 8 times with a remainder of 534.
Put 8 as the next digit of the answer. 
Result so far: 408.0
If we subtract 5280 from 5814, we get 534.
Include the next digit (2) from the dividend after 534, then repeat: 5342 / 660

Moving on to step 7:
660 goes into 5342 8 times with a remainder of 62.
The next digit of our result is 8. 
Result so far: 4088.0
Deduct 5280 from 5342 and we're left with 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 660

Going ahead to step 8:
627 divided by 660 is 0 with a remainder of 627.
The next digit of our result is 0. 
Result so far: 40880.0
Subtract 0 from 627 to get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Moving on to step 9:
660 goes into 6270 9 times with a remainder of 330.
The number 9 becomes the next digit in our result. 
Result so far: 40880.9
If we take 5940 away from 6270, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 10:
If we divide 3300 by 660, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 40880.95
The remainder is 0 after subtracting 3300 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
The number 660 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40880.95
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
660 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40880.95
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 40880.95 with a remainder of 0.0.
