We look at the division of 821387 by 75 
Let's see how many times 75 fits into 821387.

On to step 1:
If we divide 8 by 75, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 75

Advancing to step 2:
The number 75 fits into 82 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 75 from 82 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 75

Moving on to step 3:
The number 75 fits into 71 0 times, leaving a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 71, we end up with 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 75

Advancing to step 4:
The number 75 fits into 713 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 109.0
Deduct 675 from 713 and we're left with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 75

Let's proceed to step 5:
When dividing 388 by 75, we get 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 1095.0
Deduct 375 from 388 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 75

Going ahead to step 6:
75 can be fit into 137 1 times, resulting in a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 10951.0
If we take 75 away from 137, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
75 goes into 620 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 10951.8
Deduct 600 from 620 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
75 goes into 200 2 times with a remainder of 50.
The next digit of our result is 2. 
Result so far: 10951.82
Subtract 150 from 200 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.

Advancing to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 10951.826
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.

Moving on to step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 10951.8266
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.

Our division results in 10951.8266 with a remaining 0.0005.
