We're dividing 339841 by 980 
The aim is to understand the frequency of 980 in 339841.

On to step 1:
The number 980 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 980

Moving on to step 2:
If we divide 33 by 980, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 980

Step 3:
The number 980 fits into 339 0 times, leaving a remainder of 339.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 339 leaves us with 339.
Take the next digit (8) from the dividend and append it to 339, then repeat: 3398 / 980

Advancing to step 4:
The number 980 fits into 3398 3 times, leaving a remainder of 458.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2940 from 3398 and we're left with 458.
Grab the next digit (4) from the dividend, add it to 458, then carry on: 4584 / 980

Let's proceed to step 5:
4584 divided by 980 is 4 with a remainder of 664.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 3920 from 4584 and we're left with 664.
Take the next digit (1) from the dividend and append it to 664, then repeat: 6641 / 980

Moving on to step 6:
980 can be fit into 6641 6 times, resulting in a remainder of 761.
The next digit of our result is 6. 
Result so far: 346.0
The remainder is 761 after subtracting 5880 from 6641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Step 7:
7610 divided by 980 is 7 with a remainder of 750.
Put 7 as the next digit of the answer. 
Result so far: 346.7
Subtract 6860 from 7610 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 8:
980 goes into 7500 7 times with a remainder of 640.
The next digit of our result is 7. 
Result so far: 346.77
Subtracting 6860 from 7500 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final outcome is 346.77, with a leftover of 0.64.
