Let's divide 287139 by 75
Let's see how many times 75 fits into 287139.

Going ahead to step 1:
2 divided by 75 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 75

Let's proceed to step 2:
28 divided by 75 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 75

Let's proceed to step 3:
75 can be fit into 287 3 times, resulting in a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 225 away from 287, we end up with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 75

Moving on to step 4:
The number 75 fits into 621 8 times, leaving a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 600 from 621 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 75

Let's proceed to step 5:
When dividing 213 by 75, we get 2 with a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 382.0
Subtracting 150 from 213 leaves us with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 75

On to step 6:
639 divided by 75 is 8 with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 3828.0
If we take 600 away from 639, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
390 divided by 75 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3828.5
Subtracting 375 from 390 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3828.52
Deduct 150 from 150 and we're left 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:
When dividing 0 by 75, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3828.52
Deduct 0 from 0 and we're left 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 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3828.52
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.

The final outcome is 3828.52, with a leftover of 0.0.
