Let's divide 15985 by 72
Our goal is to divide 15985 by 72.

Going ahead to step 1:
72 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 72

Advancing to step 2:
72 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 72

Moving on to step 3:
The number 72 fits into 159 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 144 from 159 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 72

Going ahead to step 4:
The number 72 fits into 158 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 144 away from 158, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 72

Let's proceed to step 5:
72 can be fit into 145 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 222.0
Deduct 144 from 145 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
The number 72 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 222.0
If we subtract 0 from 10, we get 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 7:
100 divided by 72 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 222.01
Subtract 72 from 100 to 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 8:
If we divide 280 by 72, we get 3 and a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 222.013
If we take 216 away from 280, 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.

Let's proceed to step 9:
72 goes into 640 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 222.0138
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.

Let's proceed to step 10:
When dividing 640 by 72, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 222.01388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 222.01388 with a remaining 6.4e-05.
