57922515 ÷ 873 
The aim is to understand the frequency of 873 in 57922515.

On to step 1:
When dividing 5 by 873, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 873

Going ahead to step 2:
The number 873 fits into 57 0 times, leaving a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 873

Let's proceed to step 3:
873 can be fit into 579 0 times, resulting in a remainder of 579.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 579 leaves us with 579.
Fetch the next digit (2) from the dividend, attach it to 579 and continue: 5792 / 873

Moving on to step 4:
The number 873 fits into 5792 6 times, leaving a remainder of 554.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 5238 from 5792 and we're left with 554.
Fetch the next digit (2) from the dividend, attach it to 554 and continue: 5542 / 873

Going ahead to step 5:
If we divide 5542 by 873, we get 6 and a remainder of 304.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtracting 5238 from 5542 leaves us with 304.
Append the next digit (5) from the dividend to 304 and continue with: 3045 / 873

Moving on to step 6:
873 can be fit into 3045 3 times, resulting in a remainder of 426.
Record the quotient 3 as the next digit in the result. 
Result so far: 663.0
Deduct 2619 from 3045 and we're left with 426.
Bring next digit (1) of the dividend behind the 426 and repeat the process: 4261 / 873

Moving on to step 7:
The number 873 fits into 4261 4 times, leaving a remainder of 769.
The number 4 becomes the next digit in our result. 
Result so far: 6634.0
Subtract 3492 from 4261 to get 769.
Append the next digit (5) from the dividend to 769 and continue with: 7695 / 873

Moving on to step 8:
The number 873 fits into 7695 8 times, leaving a remainder of 711.
The next digit of our result is 8. 
Result so far: 66348.0
The remainder is 711 after subtracting 6984 from 7695.
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:
873 can be fit into 7110 8 times, resulting in a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 66348.8
The remainder is 126 after subtracting 6984 from 7110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 10:
The number 873 fits into 1260 1 times, leaving a remainder of 387.
Use 1 as the next digit of our solution. 
Result so far: 66348.81
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.

Step 11:
When dividing 3870 by 873, we get 4 with a remainder of 378.
Record the quotient 4 as the next digit in the result. 
Result so far: 66348.814
Subtract 3492 from 3870 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 12:
The number 873 fits into 3780 4 times, leaving a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 66348.8144
If we subtract 3492 from 3780, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 66348.8144 with a remaining 0.00288.
