Let's divide 20980087 by 753
The aim is to understand the frequency of 753 in 20980087.

Advancing to step 1:
2 divided by 753 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 753

Going ahead to step 2:
20 divided by 753 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 753

Advancing to step 3:
753 goes into 209 0 times with a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 209 and we're left with 209.
Append the next digit (8) from the dividend to 209 and continue with: 2098 / 753

Advancing to step 4:
753 can be fit into 2098 2 times, resulting in a remainder of 592.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1506 from 2098, we get 592.
Include the next digit (0) from the dividend after 592, then repeat: 5920 / 753

Going ahead to step 5:
If we divide 5920 by 753, we get 7 and a remainder of 649.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 5271 from 5920, we get 649.
Fetch the next digit (0) from the dividend, attach it to 649 and continue: 6490 / 753

Let's proceed to step 6:
6490 divided by 753 is 8 with a remainder of 466.
The next digit of our result is 8. 
Result so far: 278.0
If we subtract 6024 from 6490, we get 466.
Grab the next digit (8) from the dividend, add it to 466, then carry on: 4668 / 753

On to step 7:
The number 753 fits into 4668 6 times, leaving a remainder of 150.
The number 6 becomes the next digit in our result. 
Result so far: 2786.0
If we take 4518 away from 4668, we end up with 150.
Bring next digit (7) of the dividend behind the 150 and repeat the process: 1507 / 753

Step 8:
If we divide 1507 by 753, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 27862.0
Deduct 1506 from 1507 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 753, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 27862.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
753 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 27862.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 27862.0 with a remainder of 0.1.
