We divide 307221 by 71
We want to divide 307221 by 71.

On to step 1:
71 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 71

On to step 2:
When dividing 30 by 71, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 71

Let's proceed to step 3:
71 can be fit into 307 4 times, resulting in a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 284 from 307 to get 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 71

Moving on to step 4:
The number 71 fits into 232 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 43.0
If we take 213 away from 232, we end up with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 71

Step 5:
When dividing 192 by 71, we get 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
If we take 142 away from 192, we end up with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 71

Step 6:
If we divide 501 by 71, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4327.0
Subtract 497 from 501 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 divided by 71 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4327.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 71 fits into 400 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4327.05
Subtracting 355 from 400 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
When dividing 450 by 71, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 4327.056
Deduct 426 from 450 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
71 can be fit into 240 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 4327.0563
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
If we divide 270 by 71, we get 3 and a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 4327.05633
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 4327.05633 with a remainder of 5.7e-05.
