We want to divide 21688680 by 319.

Going ahead to step 1:
319 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 319

Going ahead to step 2:
21 divided by 319 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 319

Going ahead to step 3:
The number 319 fits into 216 0 times, leaving a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 216 after subtracting 0 from 216.
Take the next digit (8) from the dividend and append it to 216, then repeat: 2168 / 319

Moving on to step 4:
2168 divided by 319 is 6 with a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 1914 from 2168 leaves us with 254.
Take the next digit (8) from the dividend and append it to 254, then repeat: 2548 / 319

Going ahead to step 5:
319 can be fit into 2548 7 times, resulting in a remainder of 315.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 2233 from 2548 leaves us with 315.
Append the next digit (6) from the dividend to 315 and continue with: 3156 / 319

Moving on to step 6:
319 goes into 3156 9 times with a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 679.0
Subtract 2871 from 3156 to get 285.
Bring next digit (8) of the dividend behind the 285 and repeat the process: 2858 / 319

Moving on to step 7:
2858 divided by 319 is 8 with a remainder of 306.
Use 8 as the next digit of our solution. 
Result so far: 6798.0
If we take 2552 away from 2858, we end up with 306.
Take the next digit (0) from the dividend and append it to 306, then repeat: 3060 / 319

Moving on to step 8:
The number 319 fits into 3060 9 times, leaving a remainder of 189.
Put 9 as the next digit of the answer. 
Result so far: 67989.0
If we take 2871 away from 3060, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 9:
The number 319 fits into 1890 5 times, leaving a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 67989.5
Subtract 1595 from 1890 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 10:
319 goes into 2950 9 times with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 67989.59
If we take 2871 away from 2950, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
When dividing 790 by 319, we get 2 with a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 67989.592
If we subtract 638 from 790, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 12:
319 goes into 1520 4 times with a remainder of 244.
Put 4 as the next digit of the answer. 
Result so far: 67989.5924
If we take 1276 away from 1520, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 13:
The number 319 fits into 2440 7 times, leaving a remainder of 207.
The number 7 becomes the next digit in our result. 
Result so far: 67989.59247
Subtract 2233 from 2440 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 14:
The number 319 fits into 2070 6 times, leaving a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 67989.592476
If we take 1914 away from 2070, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 15:
1560 divided by 319 is 4 with a remainder of 284.
Write down 4 as next digit of the result. 
Result so far: 67989.5924764
Deduct 1276 from 1560 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 16:
The number 319 fits into 2840 8 times, leaving a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 67989.59247648
If we subtract 2552 from 2840, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 67989.59247648, with a leftover of 2.88e-07.
