156351 divided by 3 
We want to divide 156351 by 3.

Going ahead to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Step 2:
The number 3 fits into 15 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we take 15 away from 15, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Moving on to step 3:
If we divide 6 by 3, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 6 from 6, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 3

Going ahead to step 4:
If we divide 3 by 3, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 521.0
If we subtract 3 from 3, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

On to step 5:
When dividing 5 by 3, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 5211.0
If we subtract 3 from 5, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

On to step 6:
When dividing 21 by 3, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 52117.0
Subtract 21 from 21 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 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52117.0
If we subtract 0 from 0, we 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.

Let's proceed to step 8:
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: 52117.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 52117.0 with a remainder of 0.0.
