We divide 151234 by 3
We want to figure out the number of times 151234 can be divided by 3.

Moving on to step 1:
3 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

On to step 2:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 15 from 15 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Advancing to step 3:
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: 50.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Going ahead to step 4:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 504.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 3

Step 5:
If we divide 3 by 3, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 5041.0
Subtract 3 from 3 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Going ahead to step 6:
When dividing 4 by 3, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 50411.0
If we take 3 away from 4, 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.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 50411.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 50411.33
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 50411.33 with a remaining 0.001.
