Let's divide 843994 by 75
Our goal is to divide 843994 by 75.

On to step 1:
When dividing 8 by 75, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 75

Advancing to step 2:
The number 75 fits into 84 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we take 75 away from 84, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 75

Step 3:
The number 75 fits into 93 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 75 from 93 to get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 75

Moving on to step 4:
75 goes into 189 2 times with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
Subtracting 150 from 189 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 75

Moving on to step 5:
The number 75 fits into 399 5 times, leaving a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 1125.0
The remainder is 24 after subtracting 375 from 399.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 75

Advancing to step 6:
If we divide 244 by 75, we get 3 and a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 11253.0
The remainder is 19 after subtracting 225 from 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
75 can be fit into 190 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 11253.2
Deduct 150 from 190 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 75 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11253.25
Deduct 375 from 400 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
250 divided by 75 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 11253.253
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11253.2533
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 11253.2533 with a remainder of 0.00025.
