We're dividing 19998027 by 979 
The aim is to understand the frequency of 979 in 19998027.

Step 1:
1 divided by 979 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 979

Moving on to step 2:
If we divide 19 by 979, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 979

Step 3:
979 goes into 199 0 times with a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Fetch the next digit (9) from the dividend, attach it to 199 and continue: 1999 / 979

Moving on to step 4:
The number 979 fits into 1999 2 times, leaving a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1958 from 1999, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 979

Advancing to step 5:
The number 979 fits into 418 0 times, leaving a remainder of 418.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 418 and we're left with 418.
Take the next digit (0) from the dividend and append it to 418, then repeat: 4180 / 979

Let's proceed to step 6:
The number 979 fits into 4180 4 times, leaving a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
If we subtract 3916 from 4180, we get 264.
Fetch the next digit (2) from the dividend, attach it to 264 and continue: 2642 / 979

Advancing to step 7:
The number 979 fits into 2642 2 times, leaving a remainder of 684.
Record the quotient 2 as the next digit in the result. 
Result so far: 2042.0
If we subtract 1958 from 2642, we get 684.
Fetch the next digit (7) from the dividend, attach it to 684 and continue: 6847 / 979

Step 8:
6847 divided by 979 is 6 with a remainder of 973.
Record the quotient 6 as the next digit in the result. 
Result so far: 20426.0
If we take 5874 away from 6847, we end up with 973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9730, and continue the process.

Step 9:
979 goes into 9730 9 times with a remainder of 919.
Write down 9 as next digit of the result. 
Result so far: 20426.9
Subtracting 8811 from 9730 leaves us with 919.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9190, and continue the process.

Advancing to step 10:
979 goes into 9190 9 times with a remainder of 379.
Write down 9 as next digit of the result. 
Result so far: 20426.99
If we take 8811 away from 9190, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Our division results in 20426.99 with a remaining 0.379.
