72735619 divided by 68 
We want to divide 72735619 by 68.

Advancing to step 1:
If we divide 7 by 68, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 68

Moving on to step 2:
68 goes into 72 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 68 from 72 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 68

Moving on to step 3:
The number 68 fits into 47 0 times, leaving a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 47 leaves us with 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 68

On to step 4:
The number 68 fits into 473 6 times, leaving a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 408 away from 473, we end up with 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 68

Advancing to step 5:
655 divided by 68 is 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 1069.0
Subtract 612 from 655 to get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 68

Step 6:
When dividing 436 by 68, we get 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 10696.0
Deduct 408 from 436 and we're left with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 68

Step 7:
68 can be fit into 281 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 106964.0
If we subtract 272 from 281, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 68

Going ahead to step 8:
If we divide 99 by 68, we get 1 and a remainder of 31.
The next digit of our result is 1. 
Result so far: 1069641.0
Subtracting 68 from 99 leaves us with 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 9:
68 can be fit into 310 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 1069641.4
If we subtract 272 from 310, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
68 can be fit into 380 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1069641.45
Subtracting 340 from 380 leaves us with 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:
68 goes into 400 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 1069641.455
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 1069641.455, with a leftover of 0.006.
