Let's divide 253639 by 72
Our goal is to divide 253639 by 72.

Step 1:
72 goes into 2 0 times 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.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 72

Going ahead to step 2:
25 divided by 72 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 72

Advancing to step 3:
253 divided by 72 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 216 away from 253, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 72

On to step 4:
72 can be fit into 376 5 times, resulting in a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtract 360 from 376 to get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 72

Moving on to step 5:
When dividing 163 by 72, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 352.0
Deduct 144 from 163 and we're left with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 72

Advancing to step 6:
199 divided by 72 is 2 with a remainder of 55.
The next digit of our result is 2. 
Result so far: 3522.0
Subtracting 144 from 199 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
72 can be fit into 550 7 times, resulting in a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 3522.7
Subtracting 504 from 550 leaves us 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.

On to step 8:
If we divide 460 by 72, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 3522.76
If we subtract 432 from 460, 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.

Step 9:
If we divide 280 by 72, we get 3 and a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 3522.763
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.

Going ahead to step 10:
640 divided by 72 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 3522.7638
If we subtract 576 from 640, 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.

Going ahead to step 11:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 3522.76388
If we take 576 away from 640, we end up 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.

The final result is 3522.76388 with a remainder of 6.4e-05.
