Let's divide 98504121 by 373
The aim is to understand the frequency of 373 in 98504121.

Let's proceed to step 1:
373 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 373

Going ahead to step 2:
If we divide 98 by 373, we get 0 and a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Bring next digit (5) of the dividend behind the 98 and repeat the process: 985 / 373

Going ahead to step 3:
When dividing 985 by 373, we get 2 with a remainder of 239.
The next digit of our result is 2. 
Result so far: 2.0
If we take 746 away from 985, we end up with 239.
Take the next digit (0) from the dividend and append it to 239, then repeat: 2390 / 373

Let's proceed to step 4:
373 goes into 2390 6 times with a remainder of 152.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 2238 from 2390, we get 152.
Take the next digit (4) from the dividend and append it to 152, then repeat: 1524 / 373

On to step 5:
1524 divided by 373 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 264.0
If we take 1492 away from 1524, we end up with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 373

Moving on to step 6:
321 divided by 373 is 0 with a remainder of 321.
Record the quotient 0 as the next digit in the result. 
Result so far: 2640.0
Subtracting 0 from 321 leaves us with 321.
Bring next digit (2) of the dividend behind the 321 and repeat the process: 3212 / 373

Step 7:
373 goes into 3212 8 times with a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 26408.0
If we take 2984 away from 3212, we end up with 228.
Append the next digit (1) from the dividend to 228 and continue with: 2281 / 373

Advancing to step 8:
373 can be fit into 2281 6 times, resulting in a remainder of 43.
Use 6 as the next digit of our solution. 
Result so far: 264086.0
Deduct 2238 from 2281 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
If we divide 430 by 373, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 264086.1
If we subtract 373 from 430, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
If we divide 570 by 373, we get 1 and a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 264086.11
If we take 373 away from 570, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

After the division, we end up with 264086.11 and a remainder of 0.197.
