We look at the division of 38742970 by 394 
The aim is to understand the frequency of 394 in 38742970.

Let's proceed to step 1:
394 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 394

On to step 2:
If we divide 38 by 394, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 394

Advancing to step 3:
The number 394 fits into 387 0 times, leaving a remainder of 387.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 387, we get 387.
Fetch the next digit (4) from the dividend, attach it to 387 and continue: 3874 / 394

Moving on to step 4:
394 goes into 3874 9 times with a remainder of 328.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 3546 from 3874 to get 328.
Append the next digit (2) from the dividend to 328 and continue with: 3282 / 394

Step 5:
If we divide 3282 by 394, we get 8 and a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 3152 away from 3282, we end up with 130.
Append the next digit (9) from the dividend to 130 and continue with: 1309 / 394

Let's proceed to step 6:
If we divide 1309 by 394, we get 3 and a remainder of 127.
Use 3 as the next digit of our solution. 
Result so far: 983.0
Subtract 1182 from 1309 to get 127.
Fetch the next digit (7) from the dividend, attach it to 127 and continue: 1277 / 394

Moving on to step 7:
394 can be fit into 1277 3 times, resulting in a remainder of 95.
Record the quotient 3 as the next digit in the result. 
Result so far: 9833.0
If we subtract 1182 from 1277, we get 95.
Include the next digit (0) from the dividend after 95, then repeat: 950 / 394

Let's proceed to step 8:
The number 394 fits into 950 2 times, leaving a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 98332.0
Deduct 788 from 950 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 9:
When dividing 1620 by 394, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 98332.4
Subtracting 1576 from 1620 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
When dividing 440 by 394, we get 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 98332.41
If we subtract 394 from 440, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
The number 394 fits into 460 1 times, leaving a remainder of 66.
The next digit of our result is 1. 
Result so far: 98332.411
The remainder is 66 after subtracting 394 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 98332.411 with a balance of 0.0066.
