We look at the division of 212100 by 71 
We're looking to find how many times 71 goes into 212100.

On to step 1:
The number 71 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 71

Let's proceed to step 2:
21 divided by 71 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 71

Let's proceed to step 3:
The number 71 fits into 212 2 times, leaving a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 142 from 212, we get 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 71

On to step 4:
The number 71 fits into 701 9 times, leaving a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 639 from 701, we get 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 71

Moving on to step 5:
The number 71 fits into 620 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 298.0
Deduct 568 from 620 and we're left with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 71

Moving on to step 6:
When dividing 520 by 71, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 2987.0
The remainder is 23 after subtracting 497 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 71 fits into 230 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 2987.3
If we subtract 213 from 230, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
When dividing 170 by 71, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 2987.32
If we subtract 142 from 170, we get 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 9:
When dividing 280 by 71, we get 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 2987.323
The remainder is 67 after subtracting 213 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 10:
When dividing 670 by 71, we get 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 2987.3239
Deduct 639 from 670 and we're left 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.

Moving on to step 11:
310 divided by 71 is 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 2987.32394
Subtracting 284 from 310 leaves us 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 12:
When dividing 260 by 71, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 2987.323943
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.

Advancing to step 13:
470 divided by 71 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2987.3239436
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.

Advancing to step 14:
If we divide 440 by 71, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 2987.32394366
If we take 426 away from 440, we end up with 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 2987.32394366, with a leftover of 1.4e-08.
