We're dividing 212379 by 72 
Let's see how many times 72 fits into 212379.

Going ahead to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 72

Step 2:
The number 72 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 72

On to step 3:
When dividing 212 by 72, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 144 away from 212, we end up with 68.
Grab the next digit (3) from the dividend, add it to 68, then carry on: 683 / 72

Moving on to step 4:
The number 72 fits into 683 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 648 from 683 and we're left with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 72

On to step 5:
If we divide 357 by 72, we get 4 and a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Deduct 288 from 357 and we're left with 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 72

Advancing to step 6:
When dividing 699 by 72, we get 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 2949.0
If we subtract 648 from 699, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
When dividing 510 by 72, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 2949.7
Subtract 504 from 510 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 72, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 2949.7
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
If we divide 600 by 72, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 2949.708
Subtracting 576 from 600 leaves us 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.

Advancing to step 10:
The number 72 fits into 240 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 2949.7083
If we take 216 away from 240, we end up 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.

Going ahead to step 11:
72 can be fit into 240 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 2949.70833
If we take 216 away from 240, we end up 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.

The final result is 2949.70833 with a remainder of 2.4e-05.
