1223671 ÷ 72 
We're looking to find how many times 72 goes into 1223671.

Step 1:
72 can be fit into 1 0 times, resulting in 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 (2) of the dividend behind the 1 and repeat the process: 12 / 72

Advancing to step 2:
The number 72 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 72

Advancing to step 3:
72 goes into 122 1 times with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 72 away from 122, we end up with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 72

Moving on to step 4:
The number 72 fits into 503 6 times, leaving a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 432 from 503 to get 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 72

Moving on to step 5:
The number 72 fits into 716 9 times, leaving a remainder of 68.
The next digit of our result is 9. 
Result so far: 169.0
The remainder is 68 after subtracting 648 from 716.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 72

On to step 6:
72 goes into 687 9 times with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 1699.0
The remainder is 39 after subtracting 648 from 687.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 72

Moving on to step 7:
The number 72 fits into 391 5 times, leaving a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 16995.0
Subtract 360 from 391 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
If we divide 310 by 72, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 16995.4
Subtracting 288 from 310 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
When dividing 220 by 72, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 16995.43
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 72, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16995.43
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
400 divided by 72 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 16995.4305
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
72 can be fit into 400 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 16995.43055
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 16995.43055, with a leftover of 4e-05.
