67918781 ÷ 305 
We want to figure out the number of times 67918781 can be divided by 305.

Advancing to step 1:
6 divided by 305 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 305

Advancing to step 2:
305 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 305

On to step 3:
679 divided by 305 is 2 with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 610 from 679 leaves us with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 305

Moving on to step 4:
305 can be fit into 691 2 times, resulting in a remainder of 81.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 610 away from 691, we end up with 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 305

Let's proceed to step 5:
When dividing 818 by 305, we get 2 with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
If we subtract 610 from 818, we get 208.
Fetch the next digit (7) from the dividend, attach it to 208 and continue: 2087 / 305

On to step 6:
The number 305 fits into 2087 6 times, leaving a remainder of 257.
The next digit of our result is 6. 
Result so far: 2226.0
Deduct 1830 from 2087 and we're left with 257.
Fetch the next digit (8) from the dividend, attach it to 257 and continue: 2578 / 305

Going ahead to step 7:
305 goes into 2578 8 times with a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 22268.0
Subtracting 2440 from 2578 leaves us with 138.
Include the next digit (1) from the dividend after 138, then repeat: 1381 / 305

On to step 8:
The number 305 fits into 1381 4 times, leaving a remainder of 161.
Record the quotient 4 as the next digit in the result. 
Result so far: 222684.0
Subtracting 1220 from 1381 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Step 9:
The number 305 fits into 1610 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 222684.5
Deduct 1525 from 1610 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 10:
305 can be fit into 850 2 times, resulting in a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 222684.52
Subtracting 610 from 850 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
305 can be fit into 2400 7 times, resulting in a remainder of 265.
Put 7 as the next digit of the answer. 
Result so far: 222684.527
If we take 2135 away from 2400, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 12:
305 can be fit into 2650 8 times, resulting in a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 222684.5278
If we subtract 2440 from 2650, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 13:
The number 305 fits into 2100 6 times, leaving a remainder of 270.
The next digit of our result is 6. 
Result so far: 222684.52786
Deduct 1830 from 2100 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 14:
305 can be fit into 2700 8 times, resulting in a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 222684.527868
If we take 2440 away from 2700, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 15:
305 goes into 2600 8 times with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 222684.5278688
Subtract 2440 from 2600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 222684.5278688 with a remainder of 1.6e-06.
