We look at the division of 751713 by 38 
The aim is to understand the frequency of 38 in 751713.

Advancing to step 1:
If we divide 7 by 38, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 38

Moving on to step 2:
When dividing 75 by 38, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 38 away from 75, we end up with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 38

Advancing to step 3:
The number 38 fits into 371 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 342 from 371, we get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 38

Let's proceed to step 4:
When dividing 297 by 38, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Deduct 266 from 297 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 38

Let's proceed to step 5:
If we divide 311 by 38, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1978.0
Subtract 304 from 311 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 38

Going ahead to step 6:
If we divide 73 by 38, we get 1 and a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 19781.0
The remainder is 35 after subtracting 38 from 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
The number 38 fits into 350 9 times, leaving a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 19781.9
The remainder is 8 after subtracting 342 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
38 can be fit into 80 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19781.92
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
38 can be fit into 40 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 19781.921
Subtracting 38 from 40 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.

Advancing to step 10:
20 divided by 38 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 19781.921
Subtracting 0 from 20 leaves us with 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 11:
The number 38 fits into 200 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19781.92105
If we take 190 away from 200, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 38 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 19781.921052
Subtracting 76 from 100 leaves us 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.

On to step 13:
The number 38 fits into 240 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 19781.9210526
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
38 can be fit into 120 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 19781.92105263
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.

Our division results in 19781.92105263 with a remaining 6e-09.
