133171 ÷ 72 
We want to figure out the number of times 133171 can be divided by 72.

On to step 1:
72 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 72

Moving on to step 2:
The number 72 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 72

Let's proceed to step 3:
When dividing 133 by 72, we get 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 72 from 133 leaves us with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 72

Advancing to step 4:
72 goes into 611 8 times with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 576 from 611 leaves us with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 72

On to step 5:
If we divide 357 by 72, we get 4 and a remainder of 69.
The next digit of our result is 4. 
Result so far: 184.0
If we take 288 away from 357, we end up with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 72

On to step 6:
72 goes into 691 9 times with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 1849.0
If we take 648 away from 691, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
When dividing 430 by 72, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1849.5
Subtracting 360 from 430 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
The number 72 fits into 700 9 times, leaving a remainder of 52.
The number 9 becomes the next digit in our result. 
Result so far: 1849.59
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
When dividing 520 by 72, we get 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 1849.597
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 72, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 1849.5972
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1849.59722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1849.59722, with a leftover of 1.6e-05.
