Let's divide 305971 by 75
We're looking to find how many times 75 goes into 305971.

On to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 75

Moving on to step 2:
The number 75 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 75

On to step 3:
75 goes into 305 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 300 from 305 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 75

Step 4:
59 divided by 75 is 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 59 and we're left with 59.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 75

Step 5:
597 divided by 75 is 7 with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
If we subtract 525 from 597, we get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 75

Going ahead to step 6:
75 goes into 721 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 4079.0
If we take 675 away from 721, we end up 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.

On to step 7:
75 can be fit into 460 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4079.6
If we take 450 away from 460, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 75, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 4079.61
Subtract 75 from 100 to get 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.
The number 3 becomes the next digit in our result. 
Result so far: 4079.613
The remainder is 25 after subtracting 225 from 250.
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:
75 goes into 250 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 4079.6133
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 4079.6133 with a balance of 0.00025.
