We look at the division of 21584668 by 68 
We want to figure out the number of times 21584668 can be divided by 68.

Going ahead to step 1:
If we divide 2 by 68, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 68

Step 2:
When dividing 21 by 68, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 68

Moving on to step 3:
When dividing 215 by 68, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 204 from 215, we get 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 68

Step 4:
The number 68 fits into 118 1 times, leaving a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 68 from 118 to get 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 68

Going ahead to step 5:
68 goes into 504 7 times with a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 317.0
Deduct 476 from 504 and we're left with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 68

Moving on to step 6:
68 can be fit into 286 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3174.0
Deduct 272 from 286 and we're left with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 68

Going ahead to step 7:
68 goes into 146 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 31742.0
Deduct 136 from 146 and we're left with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 68

Step 8:
If we divide 108 by 68, we get 1 and a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 317421.0
Deduct 68 from 108 and we're left 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.

Going ahead to step 9:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 317421.5
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 68, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 317421.58
If we take 544 away from 600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
When dividing 560 by 68, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 317421.588
If we take 544 away from 560, we end up with 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 317421.588 and a remainder of 0.0016.
