We look at the division of 33137346 by 873 
The aim is to understand the frequency of 873 in 33137346.

Moving on to step 1:
873 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 873

On to step 2:
33 divided by 873 is 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 873

Step 3:
331 divided by 873 is 0 with a remainder of 331.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 331 to get 331.
Append the next digit (3) from the dividend to 331 and continue with: 3313 / 873

Step 4:
873 goes into 3313 3 times with a remainder of 694.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2619 from 3313, we get 694.
Include the next digit (7) from the dividend after 694, then repeat: 6947 / 873

On to step 5:
873 can be fit into 6947 7 times, resulting in a remainder of 836.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 6111 away from 6947, we end up with 836.
Include the next digit (3) from the dividend after 836, then repeat: 8363 / 873

Going ahead to step 6:
If we divide 8363 by 873, we get 9 and a remainder of 506.
Put 9 as the next digit of the answer. 
Result so far: 379.0
Deduct 7857 from 8363 and we're left with 506.
Bring next digit (4) of the dividend behind the 506 and repeat the process: 5064 / 873

Advancing to step 7:
873 can be fit into 5064 5 times, resulting in a remainder of 699.
The next digit of our result is 5. 
Result so far: 3795.0
The remainder is 699 after subtracting 4365 from 5064.
Fetch the next digit (6) from the dividend, attach it to 699 and continue: 6996 / 873

Moving on to step 8:
6996 divided by 873 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 37958.0
Subtracting 6984 from 6996 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
The number 873 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 37958.0
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
If we divide 1200 by 873, we get 1 and a remainder of 327.
The number 1 becomes the next digit in our result. 
Result so far: 37958.01
Subtracting 873 from 1200 leaves us with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 11:
873 goes into 3270 3 times with a remainder of 651.
The next digit of our result is 3. 
Result so far: 37958.013
Deduct 2619 from 3270 and we're left with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Moving on to step 12:
If we divide 6510 by 873, we get 7 and a remainder of 399.
The next digit of our result is 7. 
Result so far: 37958.0137
If we subtract 6111 from 6510, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Step 13:
873 can be fit into 3990 4 times, resulting in a remainder of 498.
Put 4 as the next digit of the answer. 
Result so far: 37958.01374
Subtracting 3492 from 3990 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 14:
4980 divided by 873 is 5 with a remainder of 615.
The number 5 becomes the next digit in our result. 
Result so far: 37958.013745
If we subtract 4365 from 4980, we get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 15:
6150 divided by 873 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 37958.0137457
Deduct 6111 from 6150 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 16:
If we divide 390 by 873, we get 0 and a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 37958.0137457
Deduct 0 from 390 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

In conclusion, the division gives 37958.0137457 with a balance of 3.9e-07.
