173161 divided by 72 
Our goal is to divide 173161 by 72.

Step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 72

Let's proceed to step 2:
The number 72 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 72

Advancing to step 3:
When dividing 173 by 72, we get 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 29 after subtracting 144 from 173.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 72

Moving on to step 4:
291 divided by 72 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 288 from 291, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 72

On to step 5:
If we divide 36 by 72, we get 0 and a remainder of 36.
The next digit of our result is 0. 
Result so far: 240.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 72

Going ahead to step 6:
72 can be fit into 361 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2405.0
If we subtract 360 from 361, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
72 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2405.0
Subtract 0 from 10 to 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.

Step 8:
72 can be fit into 100 1 times, resulting in a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 2405.01
If we subtract 72 from 100, we 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 9:
72 goes into 280 3 times with a remainder of 64.
The next digit of our result is 3. 
Result so far: 2405.013
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 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 2405.0138
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.

On to step 11:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 2405.01388
Subtracting 576 from 640 leaves us 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.

The quotient of the division is 2405.01388, and the remainder is 6.4e-05.
