84234144 ÷ 72 
We're looking to find how many times 72 goes into 84234144.

Let's proceed to step 1:
72 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 72

Moving on to step 2:
72 goes into 84 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 72 from 84 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 72

Advancing to step 3:
122 divided by 72 is 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 72 from 122 to get 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 72

Step 4:
503 divided by 72 is 6 with a remainder of 71.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtracting 432 from 503 leaves us with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 72

Going ahead to step 5:
72 can be fit into 714 9 times, resulting in a remainder of 66.
The next digit of our result is 9. 
Result so far: 1169.0
The remainder is 66 after subtracting 648 from 714.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 72

Step 6:
When dividing 661 by 72, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 11699.0
If we subtract 648 from 661, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 72

Going ahead to step 7:
72 can be fit into 134 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 116991.0
If we subtract 72 from 134, we get 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 72

Going ahead to step 8:
When dividing 624 by 72, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1169918.0
Subtracting 576 from 624 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
72 can be fit into 480 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 1169918.6
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 72 is 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 1169918.66
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 1169918.66, with a leftover of 0.048.
