39757154 ÷ 387 
The aim is to understand the frequency of 387 in 39757154.

Moving on to step 1:
387 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 387

Let's proceed to step 2:
387 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 387

On to step 3:
397 divided by 387 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 10 after subtracting 387 from 397.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 387

Step 4:
105 divided by 387 is 0 with a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 105 to get 105.
Include the next digit (7) from the dividend after 105, then repeat: 1057 / 387

Advancing to step 5:
387 can be fit into 1057 2 times, resulting in a remainder of 283.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we subtract 774 from 1057, we get 283.
Bring next digit (1) of the dividend behind the 283 and repeat the process: 2831 / 387

Let's proceed to step 6:
The number 387 fits into 2831 7 times, leaving a remainder of 122.
The number 7 becomes the next digit in our result. 
Result so far: 1027.0
Subtracting 2709 from 2831 leaves us with 122.
Fetch the next digit (5) from the dividend, attach it to 122 and continue: 1225 / 387

On to step 7:
When dividing 1225 by 387, we get 3 with a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 10273.0
Subtract 1161 from 1225 to get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 387

On to step 8:
The number 387 fits into 644 1 times, leaving a remainder of 257.
Record the quotient 1 as the next digit in the result. 
Result so far: 102731.0
Subtract 387 from 644 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 9:
2570 divided by 387 is 6 with a remainder of 248.
The next digit of our result is 6. 
Result so far: 102731.6
Subtract 2322 from 2570 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 10:
2480 divided by 387 is 6 with a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 102731.66
Subtract 2322 from 2480 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

In conclusion, the division gives 102731.66 with a balance of 0.158.
