12903894 divided by 347 
The aim is to understand the frequency of 347 in 12903894.

Going ahead to step 1:
If we divide 1 by 347, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 347

Advancing to step 2:
12 divided by 347 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 347

Going ahead to step 3:
347 can be fit into 129 0 times, resulting in a remainder of 129.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Take the next digit (0) from the dividend and append it to 129, then repeat: 1290 / 347

Going ahead to step 4:
If we divide 1290 by 347, we get 3 and a remainder of 249.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 249 after subtracting 1041 from 1290.
Bring next digit (3) of the dividend behind the 249 and repeat the process: 2493 / 347

Step 5:
When dividing 2493 by 347, we get 7 with a remainder of 64.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 2429 from 2493, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 347

Moving on to step 6:
The number 347 fits into 648 1 times, leaving a remainder of 301.
Use 1 as the next digit of our solution. 
Result so far: 371.0
The remainder is 301 after subtracting 347 from 648.
Append the next digit (9) from the dividend to 301 and continue with: 3019 / 347

On to step 7:
347 goes into 3019 8 times with a remainder of 243.
Record the quotient 8 as the next digit in the result. 
Result so far: 3718.0
If we subtract 2776 from 3019, we get 243.
Include the next digit (4) from the dividend after 243, then repeat: 2434 / 347

Going ahead to step 8:
When dividing 2434 by 347, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 37187.0
Subtracting 2429 from 2434 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
When dividing 50 by 347, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 37187.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
347 goes into 500 1 times with a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 37187.01
Subtract 347 from 500 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 11:
347 can be fit into 1530 4 times, resulting in a remainder of 142.
The number 4 becomes the next digit in our result. 
Result so far: 37187.014
If we subtract 1388 from 1530, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 12:
If we divide 1420 by 347, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 37187.0144
Subtracting 1388 from 1420 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 37187.0144 with a remaining 0.00032.
