We look at the division of 68186940 by 3 
We're looking to find how many times 3 goes into 68186940.

Step 1:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 6 from 6 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Going ahead to step 2:
When dividing 8 by 3, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 2 after subtracting 6 from 8.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Let's proceed to step 3:
3 can be fit into 21 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
The remainder is 0 after subtracting 21 from 21.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

On to step 4:
8 divided by 3 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2272.0
Subtracting 6 from 8 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 3

Moving on to step 5:
3 can be fit into 26 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 22728.0
If we subtract 24 from 26, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Advancing to step 6:
29 divided by 3 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 227289.0
The remainder is 2 after subtracting 27 from 29.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

On to step 7:
If we divide 24 by 3, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2272898.0
Deduct 24 from 24 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Let's proceed to step 8:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22728980.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 3 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22728980.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 22728980.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 22728980.0 with a remaining 0.0.
