Let's divide 84187824 by 980
The aim is to understand the frequency of 980 in 84187824.

Going ahead to step 1:
When dividing 8 by 980, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 980

Going ahead to step 2:
980 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 980

Going ahead to step 3:
980 can be fit into 841 0 times, resulting in a remainder of 841.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 841 and we're left with 841.
Bring next digit (8) of the dividend behind the 841 and repeat the process: 8418 / 980

Moving on to step 4:
If we divide 8418 by 980, we get 8 and a remainder of 578.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7840 from 8418 and we're left with 578.
Include the next digit (7) from the dividend after 578, then repeat: 5787 / 980

Step 5:
If we divide 5787 by 980, we get 5 and a remainder of 887.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 887 after subtracting 4900 from 5787.
Bring next digit (8) of the dividend behind the 887 and repeat the process: 8878 / 980

Step 6:
If we divide 8878 by 980, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 859.0
If we subtract 8820 from 8878, we get 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 980

Going ahead to step 7:
980 can be fit into 582 0 times, resulting in a remainder of 582.
The next digit of our result is 0. 
Result so far: 8590.0
If we take 0 away from 582, we end up with 582.
Take the next digit (4) from the dividend and append it to 582, then repeat: 5824 / 980

Let's proceed to step 8:
When dividing 5824 by 980, we get 5 with a remainder of 924.
The next digit of our result is 5. 
Result so far: 85905.0
Subtracting 4900 from 5824 leaves us with 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

On to step 9:
When dividing 9240 by 980, we get 9 with a remainder of 420.
Write down 9 as next digit of the result. 
Result so far: 85905.9
The remainder is 420 after subtracting 8820 from 9240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
When dividing 4200 by 980, we get 4 with a remainder of 280.
The next digit of our result is 4. 
Result so far: 85905.94
The remainder is 280 after subtracting 3920 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
When dividing 2800 by 980, we get 2 with a remainder of 840.
The number 2 becomes the next digit in our result. 
Result so far: 85905.942
Deduct 1960 from 2800 and we're left with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 12:
980 can be fit into 8400 8 times, resulting in a remainder of 560.
Use 8 as the next digit of our solution. 
Result so far: 85905.9428
The remainder is 560 after subtracting 7840 from 8400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 13:
980 goes into 5600 5 times with a remainder of 700.
The next digit of our result is 5. 
Result so far: 85905.94285
If we take 4900 away from 5600, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 14:
980 can be fit into 7000 7 times, resulting in a remainder of 140.
Record the quotient 7 as the next digit in the result. 
Result so far: 85905.942857
Subtract 6860 from 7000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
980 can be fit into 1400 1 times, resulting in a remainder of 420.
Put 1 as the next digit of the answer. 
Result so far: 85905.9428571
Subtract 980 from 1400 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 16:
980 goes into 4200 4 times with a remainder of 280.
The next digit of our result is 4. 
Result so far: 85905.94285714
The remainder is 280 after subtracting 3920 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 85905.94285714 with a remaining 2.8e-07.
