Let's divide 80901070 by 873
The aim is to understand the frequency of 873 in 80901070.

Moving on to step 1:
If we divide 8 by 873, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 873

Advancing to step 2:
When dividing 80 by 873, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 873

Moving on to step 3:
If we divide 809 by 873, we get 0 and a remainder of 809.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 809, we get 809.
Grab the next digit (0) from the dividend, add it to 809, then carry on: 8090 / 873

Going ahead to step 4:
8090 divided by 873 is 9 with a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7857 from 8090 leaves us with 233.
Append the next digit (1) from the dividend to 233 and continue with: 2331 / 873

On to step 5:
If we divide 2331 by 873, we get 2 and a remainder of 585.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtracting 1746 from 2331 leaves us with 585.
Fetch the next digit (0) from the dividend, attach it to 585 and continue: 5850 / 873

Advancing to step 6:
873 can be fit into 5850 6 times, resulting in a remainder of 612.
Record the quotient 6 as the next digit in the result. 
Result so far: 926.0
Subtracting 5238 from 5850 leaves us with 612.
Take the next digit (7) from the dividend and append it to 612, then repeat: 6127 / 873

Moving on to step 7:
6127 divided by 873 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 9267.0
If we take 6111 away from 6127, we end up with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 873

Advancing to step 8:
If we divide 160 by 873, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 92670.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
If we divide 1600 by 873, we get 1 and a remainder of 727.
The next digit of our result is 1. 
Result so far: 92670.1
Subtracting 873 from 1600 leaves us with 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Let's proceed to step 10:
When dividing 7270 by 873, we get 8 with a remainder of 286.
The next digit of our result is 8. 
Result so far: 92670.18
If we take 6984 away from 7270, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 11:
If we divide 2860 by 873, we get 3 and a remainder of 241.
The number 3 becomes the next digit in our result. 
Result so far: 92670.183
Subtracting 2619 from 2860 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 12:
873 can be fit into 2410 2 times, resulting in a remainder of 664.
Put 2 as the next digit of the answer. 
Result so far: 92670.1832
If we take 1746 away from 2410, we end up with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 13:
873 can be fit into 6640 7 times, resulting in a remainder of 529.
The next digit of our result is 7. 
Result so far: 92670.18327
The remainder is 529 after subtracting 6111 from 6640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Moving on to step 14:
The number 873 fits into 5290 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 92670.183276
Subtract 5238 from 5290 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
When dividing 520 by 873, we get 0 with a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 92670.183276
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
873 can be fit into 5200 5 times, resulting in a remainder of 835.
Write down 5 as next digit of the result. 
Result so far: 92670.18327605
The remainder is 835 after subtracting 4365 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

After the division, we end up with 92670.18327605 and a remainder of 8.35e-07.
