We divide 312215 by 71
We're looking to find how many times 71 goes into 312215.

Moving on to step 1:
3 divided by 71 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 71

Advancing to step 2:
71 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 71

Moving on to step 3:
When dividing 312 by 71, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 284 from 312, we get 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 71

Moving on to step 4:
71 goes into 282 3 times with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 213 from 282 and we're left with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 71

Going ahead to step 5:
If we divide 691 by 71, we get 9 and a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
If we take 639 away from 691, we end up with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 71

Moving on to step 6:
71 can be fit into 525 7 times, resulting in a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 4397.0
If we take 497 away from 525, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
If we divide 280 by 71, we get 3 and a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 4397.3
Subtract 213 from 280 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 8:
The number 71 fits into 670 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 4397.39
If we take 639 away from 670, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
71 goes into 310 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4397.394
Deduct 284 from 310 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
260 divided by 71 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 4397.3943
Subtract 213 from 260 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
71 goes into 470 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 4397.39436
Subtracting 426 from 470 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
440 divided by 71 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 4397.394366
The remainder is 14 after subtracting 426 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 4397.394366 and a remainder of 1.4e-06.
