15500643 divided by 72 
Let's see how many times 72 fits into 15500643.

Going ahead to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 72

Advancing to step 2:
If we divide 15 by 72, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 72

Advancing to step 3:
72 can be fit into 155 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 144 from 155, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 72

On to step 4:
If we divide 110 by 72, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 72 from 110 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 72

Going ahead to step 5:
72 goes into 380 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 215.0
Deduct 360 from 380 and we're left with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 72

Step 6:
If we divide 206 by 72, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 2152.0
Deduct 144 from 206 and we're left with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 72

Moving on to step 7:
If we divide 624 by 72, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 21528.0
Subtract 576 from 624 to get 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 72

Moving on to step 8:
72 goes into 483 6 times with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 215286.0
Subtract 432 from 483 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
When dividing 510 by 72, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 215286.7
If we take 504 away from 510, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
If we divide 60 by 72, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 215286.7
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 72, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 215286.708
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
72 goes into 240 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 215286.7083
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 215286.70833
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 215286.70833 and a remainder of 2.4e-05.
