409740 ÷ 38 
The aim is to understand the frequency of 38 in 409740.

On to step 1:
38 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 38

Going ahead to step 2:
If we divide 40 by 38, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 38 away from 40, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 38

Going ahead to step 3:
If we divide 29 by 38, we get 0 and a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 38

Moving on to step 4:
297 divided by 38 is 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 107.0
The remainder is 31 after subtracting 266 from 297.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 38

Moving on to step 5:
38 goes into 314 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
The remainder is 10 after subtracting 304 from 314.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 38

On to step 6:
100 divided by 38 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 10782.0
The remainder is 24 after subtracting 76 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
38 can be fit into 240 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 10782.6
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.

Step 8:
38 goes into 120 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 10782.63
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
38 can be fit into 60 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 10782.631
Subtracting 38 from 60 leaves us 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.

Moving on to step 10:
220 divided by 38 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10782.6315
If we take 190 away from 220, we end up 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.

Let's proceed to step 11:
300 divided by 38 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 10782.63157
If we subtract 266 from 300, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
When dividing 340 by 38, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 10782.631578
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.

Advancing to step 13:
If we divide 360 by 38, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 10782.6315789
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
38 can be fit into 180 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 10782.63157894
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 10782.63157894, with a leftover of 2.8e-08.
