We're dividing 21142171 by 72 
We want to divide 21142171 by 72.

Let's proceed to step 1:
2 divided by 72 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 72

On to step 2:
21 divided by 72 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 72

Going ahead to step 3:
If we divide 211 by 72, we get 2 and a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 144 from 211, we get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 72

Going ahead to step 4:
The number 72 fits into 674 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 648 from 674 and we're left with 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 72

Advancing to step 5:
262 divided by 72 is 3 with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 293.0
The remainder is 46 after subtracting 216 from 262.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 72

Going ahead to step 6:
The number 72 fits into 461 6 times, leaving a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 2936.0
If we take 432 away from 461, we end up with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 72

Let's proceed to step 7:
72 goes into 297 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 29364.0
The remainder is 9 after subtracting 288 from 297.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 72

Moving on to step 8:
72 can be fit into 91 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 293641.0
If we take 72 away from 91, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
72 goes into 190 2 times with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 293641.2
Deduct 144 from 190 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 72 is 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 293641.26
Subtract 432 from 460 to 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.

Moving on to step 11:
The number 72 fits into 280 3 times, leaving a remainder of 64.
The next digit of our result is 3. 
Result so far: 293641.263
If we subtract 216 from 280, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
When dividing 640 by 72, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 293641.2638
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 293641.26388
Subtracting 576 from 640 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 293641.26388 with a remaining 6.4e-05.
