Let's divide 661344 by 38
The aim is to understand the frequency of 38 in 661344.

Step 1:
38 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 38

Moving on to step 2:
38 can be fit into 66 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 38 away from 66, we end up with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 38

Let's proceed to step 3:
If we divide 281 by 38, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 266 from 281, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 38

Step 4:
38 goes into 153 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
If we subtract 152 from 153, we get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 38

Step 5:
38 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 1740.0
Subtract 0 from 14 to get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 38

Step 6:
The number 38 fits into 144 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 17403.0
Subtracting 114 from 144 leaves us with 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 7:
When dividing 300 by 38, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 17403.7
Subtracting 266 from 300 leaves us 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.

On to step 8:
38 goes into 340 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 17403.78
The remainder is 36 after subtracting 304 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 38 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 17403.789
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 38 fits into 180 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 17403.7894
If we take 152 away from 180, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
280 divided by 38 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 17403.78947
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
38 goes into 140 3 times with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 17403.789473
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
The number 38 fits into 260 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 17403.7894736
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 38, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 17403.78947368
If we take 304 away from 320, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 17403.78947368 with a balance of 1.6e-08.
