We look at the division of 96802590 by 980 
The aim is to understand the frequency of 980 in 96802590.

Let's proceed to step 1:
980 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 980

On to step 2:
980 can be fit into 96 0 times, resulting in a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 96, we end up with 96.
Append the next digit (8) from the dividend to 96 and continue with: 968 / 980

Step 3:
980 goes into 968 0 times with a remainder of 968.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 968, we get 968.
Take the next digit (0) from the dividend and append it to 968, then repeat: 9680 / 980

Advancing to step 4:
The number 980 fits into 9680 9 times, leaving a remainder of 860.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 8820 away from 9680, we end up with 860.
Include the next digit (2) from the dividend after 860, then repeat: 8602 / 980

Step 5:
The number 980 fits into 8602 8 times, leaving a remainder of 762.
Write down 8 as next digit of the result. 
Result so far: 98.0
If we take 7840 away from 8602, we end up with 762.
Append the next digit (5) from the dividend to 762 and continue with: 7625 / 980

Going ahead to step 6:
980 goes into 7625 7 times with a remainder of 765.
The number 7 becomes the next digit in our result. 
Result so far: 987.0
If we subtract 6860 from 7625, we get 765.
Include the next digit (9) from the dividend after 765, then repeat: 7659 / 980

Moving on to step 7:
980 goes into 7659 7 times with a remainder of 799.
The number 7 becomes the next digit in our result. 
Result so far: 9877.0
Subtract 6860 from 7659 to get 799.
Grab the next digit (0) from the dividend, add it to 799, then carry on: 7990 / 980

On to step 8:
If we divide 7990 by 980, we get 8 and a remainder of 150.
Write down 8 as next digit of the result. 
Result so far: 98778.0
Subtracting 7840 from 7990 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
If we divide 1500 by 980, we get 1 and a remainder of 520.
Write down 1 as next digit of the result. 
Result so far: 98778.1
If we subtract 980 from 1500, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
5200 divided by 980 is 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 98778.15
Subtracting 4900 from 5200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
The number 980 fits into 3000 3 times, leaving a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 98778.153
If we subtract 2940 from 3000, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
600 divided by 980 is 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 98778.153
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 13:
6000 divided by 980 is 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 98778.15306
If we take 5880 away from 6000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
980 can be fit into 1200 1 times, resulting in a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 98778.153061
Deduct 980 from 1200 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.

Let's proceed to step 15:
2200 divided by 980 is 2 with a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 98778.1530612
If we subtract 1960 from 2200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 16:
980 can be fit into 2400 2 times, resulting in a remainder of 440.
Record the quotient 2 as the next digit in the result. 
Result so far: 98778.15306122
Subtract 1960 from 2400 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 98778.15306122, with a leftover of 4.4e-07.
