Let's divide 71839721 by 373
The aim is to understand the frequency of 373 in 71839721.

Moving on to step 1:
When dividing 7 by 373, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 373

Step 2:
The number 373 fits into 71 0 times, leaving a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 373

Going ahead to step 3:
718 divided by 373 is 1 with a remainder of 345.
The next digit of our result is 1. 
Result so far: 1.0
If we take 373 away from 718, we end up with 345.
Include the next digit (3) from the dividend after 345, then repeat: 3453 / 373

Let's proceed to step 4:
373 can be fit into 3453 9 times, resulting in a remainder of 96.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 3357 away from 3453, we end up with 96.
Bring next digit (9) of the dividend behind the 96 and repeat the process: 969 / 373

Advancing to step 5:
373 goes into 969 2 times with a remainder of 223.
Write down 2 as next digit of the result. 
Result so far: 192.0
Deduct 746 from 969 and we're left with 223.
Include the next digit (7) from the dividend after 223, then repeat: 2237 / 373

Advancing to step 6:
373 can be fit into 2237 5 times, resulting in a remainder of 372.
The number 5 becomes the next digit in our result. 
Result so far: 1925.0
Deduct 1865 from 2237 and we're left with 372.
Bring next digit (2) of the dividend behind the 372 and repeat the process: 3722 / 373

Going ahead to step 7:
If we divide 3722 by 373, we get 9 and a remainder of 365.
Put 9 as the next digit of the answer. 
Result so far: 19259.0
Subtract 3357 from 3722 to get 365.
Include the next digit (1) from the dividend after 365, then repeat: 3651 / 373

Let's proceed to step 8:
When dividing 3651 by 373, we get 9 with a remainder of 294.
Use 9 as the next digit of our solution. 
Result so far: 192599.0
If we subtract 3357 from 3651, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 9:
The number 373 fits into 2940 7 times, leaving a remainder of 329.
Write down 7 as next digit of the result. 
Result so far: 192599.7
If we take 2611 away from 2940, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 10:
373 goes into 3290 8 times with a remainder of 306.
Use 8 as the next digit of our solution. 
Result so far: 192599.78
If we take 2984 away from 3290, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
373 goes into 3060 8 times with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 192599.788
The remainder is 76 after subtracting 2984 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 192599.788 and a remainder of 0.0076.
