We look at the division of 38898411 by 394 
The aim is to understand the frequency of 394 in 38898411.

On to step 1:
3 divided by 394 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 394

On to step 2:
394 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 394

Advancing to step 3:
The number 394 fits into 388 0 times, leaving a remainder of 388.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 388 and we're left with 388.
Include the next digit (9) from the dividend after 388, then repeat: 3889 / 394

Moving on to step 4:
3889 divided by 394 is 9 with a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 3546 away from 3889, we end up with 343.
Append the next digit (8) from the dividend to 343 and continue with: 3438 / 394

Moving on to step 5:
3438 divided by 394 is 8 with a remainder of 286.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtracting 3152 from 3438 leaves us with 286.
Append the next digit (4) from the dividend to 286 and continue with: 2864 / 394

Let's proceed to step 6:
2864 divided by 394 is 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
If we subtract 2758 from 2864, we get 106.
Fetch the next digit (1) from the dividend, attach it to 106 and continue: 1061 / 394

Step 7:
The number 394 fits into 1061 2 times, leaving a remainder of 273.
Put 2 as the next digit of the answer. 
Result so far: 9872.0
The remainder is 273 after subtracting 788 from 1061.
Bring next digit (1) of the dividend behind the 273 and repeat the process: 2731 / 394

Going ahead to step 8:
When dividing 2731 by 394, we get 6 with a remainder of 367.
Put 6 as the next digit of the answer. 
Result so far: 98726.0
If we take 2364 away from 2731, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Let's proceed to step 9:
The number 394 fits into 3670 9 times, leaving a remainder of 124.
The next digit of our result is 9. 
Result so far: 98726.9
Subtracting 3546 from 3670 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
If we divide 1240 by 394, we get 3 and a remainder of 58.
The next digit of our result is 3. 
Result so far: 98726.93
The remainder is 58 after subtracting 1182 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
394 goes into 580 1 times with a remainder of 186.
The next digit of our result is 1. 
Result so far: 98726.931
If we subtract 394 from 580, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 12:
When dividing 1860 by 394, we get 4 with a remainder of 284.
The next digit of our result is 4. 
Result so far: 98726.9314
Subtract 1576 from 1860 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
The number 394 fits into 2840 7 times, leaving a remainder of 82.
The number 7 becomes the next digit in our result. 
Result so far: 98726.93147
Deduct 2758 from 2840 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
394 can be fit into 820 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 98726.931472
If we subtract 788 from 820, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 15:
394 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 98726.931472
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 16:
When dividing 3200 by 394, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 98726.93147208
Subtract 3152 from 3200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 98726.93147208, with a leftover of 4.8e-08.
