581312 ÷ 68 
We want to figure out the number of times 581312 can be divided by 68.

On to step 1:
If we divide 5 by 68, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 68

Advancing to step 2:
58 divided by 68 is 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 68

Advancing to step 3:
The number 68 fits into 581 8 times, leaving a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 544 away from 581, we end up with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 68

Let's proceed to step 4:
The number 68 fits into 373 5 times, leaving a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtract 340 from 373 to get 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 68

Step 5:
331 divided by 68 is 4 with a remainder of 59.
The next digit of our result is 4. 
Result so far: 854.0
Subtracting 272 from 331 leaves us with 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 68

Advancing to step 6:
68 goes into 592 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8548.0
Subtract 544 from 592 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.

Advancing to step 7:
The number 68 fits into 480 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 8548.7
Deduct 476 from 480 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.

Advancing to step 8:
68 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8548.7
If we take 0 away from 40, we end up 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.

Step 9:
If we divide 400 by 68, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 8548.705
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
68 can be fit into 600 8 times, resulting in a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8548.7058
The remainder is 56 after subtracting 544 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
68 goes into 560 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8548.70588
Subtract 544 from 560 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.

After the division, we end up with 8548.70588 and a remainder of 1.6e-05.
