980490 ÷ 27 
The aim is to understand the frequency of 27 in 980490.

Advancing to step 1:
If we divide 9 by 27, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 27

Step 2:
When dividing 98 by 27, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 81 from 98 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 27

Advancing to step 3:
27 goes into 170 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 162 away from 170, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 27

Going ahead to step 4:
The number 27 fits into 84 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 363.0
If we take 81 away from 84, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 27

Let's proceed to step 5:
If we divide 39 by 27, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 3631.0
Deduct 27 from 39 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 27

On to step 6:
120 divided by 27 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 36314.0
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 27 fits into 120 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 36314.4
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
27 goes into 120 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 36314.44
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 36314.44, with a leftover of 0.012.
