We're dividing 19311393 by 724 
The aim is to understand the frequency of 724 in 19311393.

Advancing to step 1:
1 divided by 724 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 724

Going ahead to step 2:
The number 724 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 724

Moving on to step 3:
If we divide 193 by 724, we get 0 and a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 193, we get 193.
Fetch the next digit (1) from the dividend, attach it to 193 and continue: 1931 / 724

Moving on to step 4:
724 can be fit into 1931 2 times, resulting in a remainder of 483.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1448 away from 1931, we end up with 483.
Grab the next digit (1) from the dividend, add it to 483, then carry on: 4831 / 724

Going ahead to step 5:
724 can be fit into 4831 6 times, resulting in a remainder of 487.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 4344 from 4831, we get 487.
Take the next digit (3) from the dividend and append it to 487, then repeat: 4873 / 724

Moving on to step 6:
4873 divided by 724 is 6 with a remainder of 529.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Subtracting 4344 from 4873 leaves us with 529.
Include the next digit (9) from the dividend after 529, then repeat: 5299 / 724

Step 7:
5299 divided by 724 is 7 with a remainder of 231.
The next digit of our result is 7. 
Result so far: 2667.0
Deduct 5068 from 5299 and we're left with 231.
Grab the next digit (3) from the dividend, add it to 231, then carry on: 2313 / 724

Going ahead to step 8:
The number 724 fits into 2313 3 times, leaving a remainder of 141.
The next digit of our result is 3. 
Result so far: 26673.0
If we subtract 2172 from 2313, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
724 goes into 1410 1 times with a remainder of 686.
The next digit of our result is 1. 
Result so far: 26673.1
If we subtract 724 from 1410, we get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Step 10:
724 goes into 6860 9 times with a remainder of 344.
Record the quotient 9 as the next digit in the result. 
Result so far: 26673.19
The remainder is 344 after subtracting 6516 from 6860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
If we divide 3440 by 724, we get 4 and a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 26673.194
Deduct 2896 from 3440 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

On to step 12:
When dividing 5440 by 724, we get 7 with a remainder of 372.
The next digit of our result is 7. 
Result so far: 26673.1947
The remainder is 372 after subtracting 5068 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 13:
When dividing 3720 by 724, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 26673.19475
Subtracting 3620 from 3720 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
The number 724 fits into 1000 1 times, leaving a remainder of 276.
The next digit of our result is 1. 
Result so far: 26673.194751
If we take 724 away from 1000, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 15:
724 can be fit into 2760 3 times, resulting in a remainder of 588.
The next digit of our result is 3. 
Result so far: 26673.1947513
Deduct 2172 from 2760 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 16:
724 can be fit into 5880 8 times, resulting in a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 26673.19475138
The remainder is 88 after subtracting 5792 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 26673.19475138 with a balance of 8.8e-08.
