918145 divided by 3 
Let's see how many times 3 fits into 918145.

Step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 2:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

On to step 3:
18 divided by 3 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
If we subtract 18 from 18, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Going ahead to step 4:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 3060.0
Subtract 0 from 1 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Step 5:
When dividing 14 by 3, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 30604.0
The remainder is 2 after subtracting 12 from 14.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Moving on to step 6:
25 divided by 3 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 306048.0
Subtracting 24 from 25 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 306048.3
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 306048.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 306048.33, and the remainder is 0.001.
