Let's divide 72509257 by 53
We're looking to find how many times 53 goes into 72509257.

On to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 53

Moving on to step 2:
When dividing 72 by 53, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 53 from 72 and we're left with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 53

Advancing to step 3:
The number 53 fits into 195 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 159 from 195, we get 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 53

Advancing to step 4:
When dividing 360 by 53, we get 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtract 318 from 360 to get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 53

Advancing to step 5:
The number 53 fits into 429 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 1368.0
Deduct 424 from 429 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 53

Step 6:
53 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 13680.0
Subtracting 0 from 52 leaves us with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 53

Step 7:
The number 53 fits into 525 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 136809.0
If we subtract 477 from 525, we get 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 53

Advancing to step 8:
The number 53 fits into 487 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 1368099.0
Subtracting 477 from 487 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
53 can be fit into 100 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 1368099.1
Subtracting 53 from 100 leaves us 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.

Going ahead to step 10:
470 divided by 53 is 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 1368099.18
Subtract 424 from 470 to get 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 11:
If we divide 460 by 53, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 1368099.188
If we take 424 away from 460, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 1368099.188, with a leftover of 0.0036.
