15019 ÷ 72 
We want to figure out the number of times 15019 can be divided by 72.

Step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 72

On to step 2:
When dividing 15 by 72, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 72

Moving on to step 3:
The number 72 fits into 150 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 144 from 150, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 72

Let's proceed to step 4:
When dividing 61 by 72, we get 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 61, we get 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 72

Step 5:
If we divide 619 by 72, we get 8 and a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 208.0
If we subtract 576 from 619, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 6:
430 divided by 72 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 208.5
If we subtract 360 from 430, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
If we divide 700 by 72, we get 9 and a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 208.59
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
72 goes into 520 7 times with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 208.597
Deduct 504 from 520 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.

Advancing to step 9:
72 can be fit into 160 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 208.5972
If we take 144 away from 160, 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.

Going ahead to step 10:
72 can be fit into 160 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 208.59722
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.

The final outcome is 208.59722, with a leftover of 1.6e-05.
