809431 divided by 38 
The aim is to understand the frequency of 38 in 809431.

Moving on to step 1:
8 divided by 38 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 38

Let's proceed to step 2:
38 can be fit into 80 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 76 from 80 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 38

On to step 3:
38 can be fit into 49 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 38 from 49 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 38

Going ahead to step 4:
When dividing 114 by 38, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 213.0
The remainder is 0 after subtracting 114 from 114.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 38

Moving on to step 5:
38 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 2130.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 38

On to step 6:
31 divided by 38 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 21300.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
The number 38 fits into 310 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 21300.8
Subtract 304 from 310 to get 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 8:
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: 21300.81
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
220 divided by 38 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 21300.815
Deduct 190 from 220 and we're left 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 10:
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: 21300.8157
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.

Let's proceed to step 11:
If we divide 340 by 38, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 21300.81578
Deduct 304 from 340 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 38 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 21300.815789
If we subtract 342 from 360, we 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.

Let's proceed to step 13:
180 divided by 38 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 21300.8157894
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.

Let's proceed to step 14:
When dividing 280 by 38, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 21300.81578947
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.

The quotient of the division is 21300.81578947, and the remainder is 1.4e-08.
