39754275 ÷ 873 
The aim is to understand the frequency of 873 in 39754275.

On to step 1:
873 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 873

Step 2:
If we divide 39 by 873, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 873

Going ahead to step 3:
If we divide 397 by 873, we get 0 and a remainder of 397.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 397 leaves us with 397.
Include the next digit (5) from the dividend after 397, then repeat: 3975 / 873

Let's proceed to step 4:
3975 divided by 873 is 4 with a remainder of 483.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3492 away from 3975, we end up with 483.
Include the next digit (4) from the dividend after 483, then repeat: 4834 / 873

Step 5:
873 can be fit into 4834 5 times, resulting in a remainder of 469.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 4365 from 4834, we get 469.
Append the next digit (2) from the dividend to 469 and continue with: 4692 / 873

Advancing to step 6:
4692 divided by 873 is 5 with a remainder of 327.
Write down 5 as next digit of the result. 
Result so far: 455.0
If we subtract 4365 from 4692, we get 327.
Fetch the next digit (7) from the dividend, attach it to 327 and continue: 3277 / 873

Moving on to step 7:
873 can be fit into 3277 3 times, resulting in a remainder of 658.
The number 3 becomes the next digit in our result. 
Result so far: 4553.0
Subtracting 2619 from 3277 leaves us with 658.
Append the next digit (5) from the dividend to 658 and continue with: 6585 / 873

Advancing to step 8:
6585 divided by 873 is 7 with a remainder of 474.
Use 7 as the next digit of our solution. 
Result so far: 45537.0
Subtract 6111 from 6585 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
The number 873 fits into 4740 5 times, leaving a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 45537.5
If we subtract 4365 from 4740, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 10:
873 can be fit into 3750 4 times, resulting in a remainder of 258.
The next digit of our result is 4. 
Result so far: 45537.54
Subtracting 3492 from 3750 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 11:
When dividing 2580 by 873, we get 2 with a remainder of 834.
The next digit of our result is 2. 
Result so far: 45537.542
Subtracting 1746 from 2580 leaves us with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Step 12:
873 goes into 8340 9 times with a remainder of 483.
Use 9 as the next digit of our solution. 
Result so far: 45537.5429
Subtracting 7857 from 8340 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 13:
873 can be fit into 4830 5 times, resulting in a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 45537.54295
Subtract 4365 from 4830 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Moving on to step 14:
The number 873 fits into 4650 5 times, leaving a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 45537.542955
If we subtract 4365 from 4650, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Our division results in 45537.542955 with a remaining 2.85e-05.
