We're dividing 38253099 by 974 
The aim is to understand the frequency of 974 in 38253099.

On to step 1:
3 divided by 974 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 974

Going ahead to step 2:
974 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 974

Let's proceed to step 3:
382 divided by 974 is 0 with a remainder of 382.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 382, we end up with 382.
Take the next digit (5) from the dividend and append it to 382, then repeat: 3825 / 974

Let's proceed to step 4:
If we divide 3825 by 974, we get 3 and a remainder of 903.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 903 after subtracting 2922 from 3825.
Bring next digit (3) of the dividend behind the 903 and repeat the process: 9033 / 974

Step 5:
974 can be fit into 9033 9 times, resulting in a remainder of 267.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 8766 from 9033 and we're left with 267.
Append the next digit (0) from the dividend to 267 and continue with: 2670 / 974

On to step 6:
974 goes into 2670 2 times with a remainder of 722.
Use 2 as the next digit of our solution. 
Result so far: 392.0
If we subtract 1948 from 2670, we get 722.
Take the next digit (9) from the dividend and append it to 722, then repeat: 7229 / 974

Moving on to step 7:
974 goes into 7229 7 times with a remainder of 411.
Record the quotient 7 as the next digit in the result. 
Result so far: 3927.0
Subtracting 6818 from 7229 leaves us with 411.
Include the next digit (9) from the dividend after 411, then repeat: 4119 / 974

Step 8:
If we divide 4119 by 974, we get 4 and a remainder of 223.
The next digit of our result is 4. 
Result so far: 39274.0
Subtracting 3896 from 4119 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 9:
When dividing 2230 by 974, we get 2 with a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 39274.2
The remainder is 282 after subtracting 1948 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 10:
The number 974 fits into 2820 2 times, leaving a remainder of 872.
Put 2 as the next digit of the answer. 
Result so far: 39274.22
Deduct 1948 from 2820 and we're left with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

The final outcome is 39274.22, with a leftover of 0.872.
