We're dividing 842573 by 75 
We want to figure out the number of times 842573 can be divided by 75.

Let's proceed to step 1:
8 divided by 75 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 75

On to step 2:
The number 75 fits into 84 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 75 from 84 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 75

Moving on to step 3:
When dividing 92 by 75, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 75 away from 92, we end up with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 75

Step 4:
When dividing 175 by 75, we get 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Deduct 150 from 175 and we're left with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 75

Let's proceed to step 5:
257 divided by 75 is 3 with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 1123.0
If we take 225 away from 257, we end up with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 75

Advancing to step 6:
323 divided by 75 is 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 11234.0
Subtracting 300 from 323 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
75 can be fit into 230 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 11234.3
If we take 225 away from 230, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
The number 75 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 11234.3
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 11234.306
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 11234.3066
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 11234.3066 with a remainder of 0.0005.
