212389 ÷ 71 
Our goal is to divide 212389 by 71.

Let's proceed to step 1:
2 divided by 71 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 71

Step 2:
71 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 71

Step 3:
212 divided by 71 is 2 with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 142 away from 212, we end up with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 71

On to step 4:
The number 71 fits into 703 9 times, leaving a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 639 from 703 and we're left with 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 71

Let's proceed to step 5:
When dividing 648 by 71, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 299.0
The remainder is 9 after subtracting 639 from 648.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 71

Moving on to step 6:
71 goes into 99 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 2991.0
Subtracting 71 from 99 leaves us 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.

On to step 7:
The number 71 fits into 280 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 2991.3
Subtracting 213 from 280 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 8:
670 divided by 71 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 2991.39
The remainder is 31 after subtracting 639 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
71 can be fit into 310 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2991.394
If we take 284 away from 310, we end up 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.

Step 10:
260 divided by 71 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2991.3943
Deduct 213 from 260 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
If we divide 470 by 71, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2991.39436
Subtract 426 from 470 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
71 goes into 440 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 2991.394366
Subtract 426 from 440 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 2991.394366, with a leftover of 1.4e-06.
