17123 ÷ 72 
We want to divide 17123 by 72.

Let's proceed to step 1:
72 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 72

Going ahead to step 2:
If we divide 17 by 72, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 72

Going ahead to step 3:
171 divided by 72 is 2 with a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 27 after subtracting 144 from 171.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 72

Let's proceed to step 4:
72 goes into 272 3 times with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 216 from 272 leaves us with 56.
Take the next digit (3) from the dividend and append it to 56, then repeat: 563 / 72

Going ahead to step 5:
72 goes into 563 7 times with a remainder of 59.
The next digit of our result is 7. 
Result so far: 237.0
If we subtract 504 from 563, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 6:
72 goes into 590 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 237.8
Subtract 576 from 590 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
72 goes into 140 1 times with a remainder of 68.
The next digit of our result is 1. 
Result so far: 237.81
If we take 72 away from 140, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
If we divide 680 by 72, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 237.819
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 237.8194
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
320 divided by 72 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 237.81944
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 237.81944 with a remainder of 3.2e-05.
