We divide 18089733 by 873
The aim is to understand the frequency of 873 in 18089733.

On to step 1:
The number 873 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 873

On to step 2:
When dividing 18 by 873, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 873

On to step 3:
If we divide 180 by 873, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 180, we end up with 180.
Append the next digit (8) from the dividend to 180 and continue with: 1808 / 873

Moving on to step 4:
The number 873 fits into 1808 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1746 from 1808 and we're left with 62.
Grab the next digit (9) from the dividend, add it to 62, then carry on: 629 / 873

Moving on to step 5:
873 can be fit into 629 0 times, resulting in a remainder of 629.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 629 after subtracting 0 from 629.
Grab the next digit (7) from the dividend, add it to 629, then carry on: 6297 / 873

Advancing to step 6:
When dividing 6297 by 873, we get 7 with a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtracting 6111 from 6297 leaves us with 186.
Grab the next digit (3) from the dividend, add it to 186, then carry on: 1863 / 873

Going ahead to step 7:
873 can be fit into 1863 2 times, resulting in a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 2072.0
If we take 1746 away from 1863, we end up with 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 873

Moving on to step 8:
1173 divided by 873 is 1 with a remainder of 300.
Record the quotient 1 as the next digit in the result. 
Result so far: 20721.0
Subtract 873 from 1173 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 9:
873 can be fit into 3000 3 times, resulting in a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 20721.3
The remainder is 381 after subtracting 2619 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 10:
3810 divided by 873 is 4 with a remainder of 318.
The next digit of our result is 4. 
Result so far: 20721.34
Subtract 3492 from 3810 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 11:
When dividing 3180 by 873, we get 3 with a remainder of 561.
Use 3 as the next digit of our solution. 
Result so far: 20721.343
Subtract 2619 from 3180 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Let's proceed to step 12:
If we divide 5610 by 873, we get 6 and a remainder of 372.
Put 6 as the next digit of the answer. 
Result so far: 20721.3436
If we subtract 5238 from 5610, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 13:
873 can be fit into 3720 4 times, resulting in a remainder of 228.
Put 4 as the next digit of the answer. 
Result so far: 20721.34364
Deduct 3492 from 3720 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 14:
When dividing 2280 by 873, we get 2 with a remainder of 534.
The next digit of our result is 2. 
Result so far: 20721.343642
Subtracting 1746 from 2280 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 15:
The number 873 fits into 5340 6 times, leaving a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 20721.3436426
Subtracting 5238 from 5340 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 16:
The number 873 fits into 1020 1 times, leaving a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 20721.34364261
Deduct 873 from 1020 and we're left with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

In conclusion, the division gives 20721.34364261 with a balance of 1.47e-07.
