We look at the division of 252457 by 72 
We want to figure out the number of times 252457 can be divided by 72.

Going ahead to step 1:
72 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 72

Step 2:
72 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 72

Step 3:
252 divided by 72 is 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 36 after subtracting 216 from 252.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 72

On to step 4:
364 divided by 72 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 360 from 364 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 72

Going ahead to step 5:
45 divided by 72 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 350.0
Deduct 0 from 45 and we're left with 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 72

Moving on to step 6:
When dividing 457 by 72, we get 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 3506.0
The remainder is 25 after subtracting 432 from 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
The number 72 fits into 250 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 3506.3
Deduct 216 from 250 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
72 can be fit into 340 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 3506.34
The remainder is 52 after subtracting 288 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
72 can be fit into 520 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 3506.347
If we take 504 away from 520, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 3506.3472
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3506.34722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 3506.34722 and a remainder of 1.6e-05.
