We're dividing 843993 by 75 
We're looking to find how many times 75 goes into 843993.

Moving on to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 75

Advancing to step 2:
When dividing 84 by 75, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 75 from 84, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 75

Let's proceed to step 3:
75 can be fit into 93 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 75 away from 93, we end up with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 75

Going ahead to step 4:
The number 75 fits into 189 2 times, leaving a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 112.0
The remainder is 39 after subtracting 150 from 189.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 75

Let's proceed to step 5:
75 can be fit into 399 5 times, resulting in a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 1125.0
If we subtract 375 from 399, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 75

On to step 6:
If we divide 243 by 75, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 11253.0
Subtracting 225 from 243 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
75 can be fit into 180 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 11253.2
If we take 150 away from 180, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 75, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 11253.24
If we take 300 away from 300, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11253.24
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 75 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11253.24
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 11253.24 and a remainder of 0.0.
