723913 ÷ 68 
We're looking to find how many times 68 goes into 723913.

Step 1:
7 divided by 68 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 68

Step 2:
68 goes into 72 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 68 away from 72, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 68

On to step 3:
If we divide 43 by 68, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (9) from the dividend, attach it to 43 and continue: 439 / 68

On to step 4:
68 goes into 439 6 times with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 106.0
Subtracting 408 from 439 leaves us with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 68

Going ahead to step 5:
The number 68 fits into 311 4 times, leaving a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 1064.0
If we subtract 272 from 311, we get 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 68

Going ahead to step 6:
393 divided by 68 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 10645.0
Deduct 340 from 393 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
The number 68 fits into 530 7 times, leaving a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 10645.7
If we subtract 476 from 530, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
68 goes into 540 7 times with a remainder of 64.
Write down 7 as next digit of the result. 
Result so far: 10645.77
If we subtract 476 from 540, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 10645.77 with a remaining 0.064.
