286124 ÷ 75 
We're looking to find how many times 75 goes into 286124.

On to step 1:
If we divide 2 by 75, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 75

On to step 2:
If we divide 28 by 75, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 75

On to step 3:
If we divide 286 by 75, we get 3 and a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 225 from 286, we get 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 75

On to step 4:
75 can be fit into 611 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 600 from 611 to get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 75

Moving on to step 5:
The number 75 fits into 112 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 381.0
Subtracting 75 from 112 leaves us with 37.
Grab the next digit (4) from the dividend, add it to 37, then carry on: 374 / 75

Let's proceed to step 6:
The number 75 fits into 374 4 times, leaving a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 3814.0
If we subtract 300 from 374, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
The number 75 fits into 740 9 times, leaving a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 3814.9
If we take 675 away from 740, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 8:
The number 75 fits into 650 8 times, leaving a remainder of 50.
The next digit of our result is 8. 
Result so far: 3814.98
Deduct 600 from 650 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.

Going ahead to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 3814.986
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.

On to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 3814.9866
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 3814.9866 with a remaining 0.0005.
