721774 divided by 38 
The aim is to understand the frequency of 38 in 721774.

Step 1:
When dividing 7 by 38, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 38

Moving on to step 2:
38 can be fit into 72 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 38 from 72, we get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 38

Let's proceed to step 3:
If we divide 341 by 38, we get 8 and a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 304 from 341, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 38

Going ahead to step 4:
38 can be fit into 377 9 times, resulting in a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 189.0
If we take 342 away from 377, we end up with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 38

Moving on to step 5:
357 divided by 38 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1899.0
If we take 342 away from 357, we end up with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 38

Step 6:
38 goes into 154 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 18994.0
Subtracting 152 from 154 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
38 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 18994.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 38, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 18994.05
If we subtract 190 from 200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
38 goes into 100 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 18994.052
If we take 76 away from 100, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 38, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 18994.0526
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 38 fits into 120 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 18994.05263
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
When dividing 60 by 38, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 18994.052631
If we take 38 away from 60, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
38 can be fit into 220 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 18994.0526315
Subtract 190 from 220 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
38 can be fit into 300 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 18994.05263157
Deduct 266 from 300 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 18994.05263157 with a balance of 3.4e-08.
