We're dividing 23658138 by 873 
The aim is to understand the frequency of 873 in 23658138.

On to step 1:
2 divided by 873 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 873

On to step 2:
23 divided by 873 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 873

Step 3:
873 can be fit into 236 0 times, resulting in a remainder of 236.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 236 after subtracting 0 from 236.
Grab the next digit (5) from the dividend, add it to 236, then carry on: 2365 / 873

Moving on to step 4:
The number 873 fits into 2365 2 times, leaving a remainder of 619.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1746 from 2365 and we're left with 619.
Fetch the next digit (8) from the dividend, attach it to 619 and continue: 6198 / 873

Let's proceed to step 5:
The number 873 fits into 6198 7 times, leaving a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 6111 from 6198 and we're left with 87.
Take the next digit (1) from the dividend and append it to 87, then repeat: 871 / 873

Going ahead to step 6:
873 goes into 871 0 times with a remainder of 871.
Write down 0 as next digit of the result. 
Result so far: 270.0
Deduct 0 from 871 and we're left with 871.
Grab the next digit (3) from the dividend, add it to 871, then carry on: 8713 / 873

Step 7:
When dividing 8713 by 873, we get 9 with a remainder of 856.
The next digit of our result is 9. 
Result so far: 2709.0
If we subtract 7857 from 8713, we get 856.
Include the next digit (8) from the dividend after 856, then repeat: 8568 / 873

Moving on to step 8:
8568 divided by 873 is 9 with a remainder of 711.
Use 9 as the next digit of our solution. 
Result so far: 27099.0
If we take 7857 away from 8568, we end up with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Going ahead to step 9:
If we divide 7110 by 873, we get 8 and a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 27099.8
Deduct 6984 from 7110 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 10:
873 can be fit into 1260 1 times, resulting in a remainder of 387.
Use 1 as the next digit of our solution. 
Result so far: 27099.81
Subtracting 873 from 1260 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Let's proceed to step 11:
873 can be fit into 3870 4 times, resulting in a remainder of 378.
Record the quotient 4 as the next digit in the result. 
Result so far: 27099.814
Subtracting 3492 from 3870 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 12:
The number 873 fits into 3780 4 times, leaving a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 27099.8144
The remainder is 288 after subtracting 3492 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

In conclusion, the division gives 27099.8144 with a balance of 0.00288.
