98353049 divided by 873 
The aim is to understand the frequency of 873 in 98353049.

Advancing to step 1:
9 divided by 873 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 873

Let's proceed to step 2:
If we divide 98 by 873, we get 0 and a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 873

Moving on to step 3:
The number 873 fits into 983 1 times, leaving a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 873 from 983 leaves us with 110.
Grab the next digit (5) from the dividend, add it to 110, then carry on: 1105 / 873

Moving on to step 4:
873 can be fit into 1105 1 times, resulting in a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 873 from 1105, we get 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 873

Let's proceed to step 5:
873 can be fit into 2323 2 times, resulting in a remainder of 577.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtract 1746 from 2323 to get 577.
Take the next digit (0) from the dividend and append it to 577, then repeat: 5770 / 873

Step 6:
873 can be fit into 5770 6 times, resulting in a remainder of 532.
Write down 6 as next digit of the result. 
Result so far: 1126.0
The remainder is 532 after subtracting 5238 from 5770.
Take the next digit (4) from the dividend and append it to 532, then repeat: 5324 / 873

On to step 7:
5324 divided by 873 is 6 with a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 11266.0
If we take 5238 away from 5324, we end up with 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 873

Let's proceed to step 8:
869 divided by 873 is 0 with a remainder of 869.
Use 0 as the next digit of our solution. 
Result so far: 112660.0
Deduct 0 from 869 and we're left with 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

On to step 9:
873 goes into 8690 9 times with a remainder of 833.
Put 9 as the next digit of the answer. 
Result so far: 112660.9
If we take 7857 away from 8690, we end up with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Going ahead to step 10:
873 goes into 8330 9 times with a remainder of 473.
The next digit of our result is 9. 
Result so far: 112660.99
The remainder is 473 after subtracting 7857 from 8330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

After the division, we end up with 112660.99 and a remainder of 0.473.
