161105 ÷ 72 
Let's see how many times 72 fits into 161105.

Advancing to step 1:
When dividing 1 by 72, we get 0 with 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.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 72

Going ahead to step 2:
The number 72 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 72

Advancing to step 3:
If we divide 161 by 72, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 17 after subtracting 144 from 161.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 72

Let's proceed to step 4:
The number 72 fits into 171 2 times, leaving a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 27 after subtracting 144 from 171.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 72

Let's proceed to step 5:
270 divided by 72 is 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 223.0
If we take 216 away from 270, we end up with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 72

Advancing to step 6:
If we divide 545 by 72, we get 7 and a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 2237.0
Subtracting 504 from 545 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
72 can be fit into 410 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 2237.5
The remainder is 50 after subtracting 360 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 72 fits into 500 6 times, leaving a remainder of 68.
The next digit of our result is 6. 
Result so far: 2237.56
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.

Going ahead to step 9:
72 can be fit into 680 9 times, resulting in a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 2237.569
If we subtract 648 from 680, we 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.

Let's proceed to step 10:
320 divided by 72 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 2237.5694
The remainder is 32 after subtracting 288 from 320.
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:
If we divide 320 by 72, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 2237.56944
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 2237.56944 with a remaining 3.2e-05.
