We look at the division of 159539 by 75 
Let's see how many times 75 fits into 159539.

On to step 1:
If we divide 1 by 75, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 75

On to step 2:
75 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 75

Let's proceed to step 3:
75 can be fit into 159 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 150 from 159, we get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 75

Step 4:
The number 75 fits into 95 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 75 from 95 and we're left with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 75

On to step 5:
When dividing 203 by 75, we get 2 with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 212.0
Deduct 150 from 203 and we're left with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 75

Advancing to step 6:
When dividing 539 by 75, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 2127.0
If we take 525 away from 539, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 75, we get 1 and a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 2127.1
If we take 75 away from 140, 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:
When dividing 650 by 75, we get 8 with a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 2127.18
The remainder is 50 after subtracting 600 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
500 divided by 75 is 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 2127.186
If we subtract 450 from 500, we 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.

Moving on to step 10:
75 goes into 500 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 2127.1866
Subtracting 450 from 500 leaves us 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.

The final outcome is 2127.1866, with a leftover of 0.0005.
