Let's divide 400556 by 3
We want to divide 400556 by 3.

Going ahead to step 1:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 3 from 4 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Step 2:
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: 13.0
Subtracting 9 from 10 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Let's proceed to step 3:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 9 from 10 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

On to step 4:
3 goes into 15 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1335.0
Subtract 15 from 15 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Advancing to step 5:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 13351.0
The remainder is 2 after subtracting 3 from 5.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Going ahead to step 6:
If we divide 26 by 3, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 133518.0
Subtract 24 from 26 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 133518.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
20 divided by 3 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 133518.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 133518.66 with a remaining 0.002.
