We're dividing 439171 by 75 
We want to divide 439171 by 75.

Let's proceed to step 1:
75 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 75

Let's proceed to step 2:
43 divided by 75 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 75

Advancing to step 3:
75 goes into 439 5 times with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 375 from 439, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 75

Going ahead to step 4:
When dividing 641 by 75, we get 8 with a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
The remainder is 41 after subtracting 600 from 641.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 75

On to step 5:
When dividing 417 by 75, we get 5 with a remainder of 42.
The next digit of our result is 5. 
Result so far: 585.0
If we subtract 375 from 417, we get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 75

Let's proceed to step 6:
When dividing 421 by 75, we get 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 5855.0
Deduct 375 from 421 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
When dividing 460 by 75, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 5855.6
Subtract 450 from 460 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 75 fits into 100 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 5855.61
If we take 75 away from 100, 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.

Moving on to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 5855.613
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.

Advancing to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 5855.6133
Deduct 225 from 250 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.

The final outcome is 5855.6133, with a leftover of 0.00025.
