We're dividing 171617 by 72 
Our goal is to divide 171617 by 72.

Advancing to step 1:
When dividing 1 by 72, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 72

Step 2:
When dividing 17 by 72, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 72

Moving on to step 3:
The number 72 fits into 171 2 times, leaving a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 144 from 171 and we're left with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 72

Step 4:
The number 72 fits into 276 3 times, leaving a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 60 after subtracting 216 from 276.
Fetch the next digit (1) from the dividend, attach it to 60 and continue: 601 / 72

On to step 5:
If we divide 601 by 72, we get 8 and a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 238.0
If we subtract 576 from 601, we get 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 72

Advancing to step 6:
72 goes into 257 3 times with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 2383.0
If we subtract 216 from 257, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
The number 72 fits into 410 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2383.5
Subtracting 360 from 410 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
500 divided by 72 is 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 2383.56
Deduct 432 from 500 and we're left 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.

Advancing to step 9:
72 can be fit into 680 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 2383.569
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.

Let's proceed to step 10:
When dividing 320 by 72, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 2383.5694
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.

Advancing to step 11:
When dividing 320 by 72, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 2383.56944
Subtract 288 from 320 to get 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 outcome is 2383.56944, with a leftover of 3.2e-05.
