We divide 131213 by 3
We're looking to find how many times 3 goes into 131213.

Let's proceed to step 1:
If we divide 1 by 3, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Moving on to step 2:
3 goes into 13 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 1 after subtracting 12 from 13.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Let's proceed to step 3:
If we divide 11 by 3, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 43.0
Subtracting 9 from 11 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

On to step 4:
3 goes into 22 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
If we take 21 away from 22, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 3

Advancing to step 5:
When dividing 11 by 3, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 4373.0
Deduct 9 from 11 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Step 6:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 43737.0
The remainder is 2 after subtracting 21 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 43737.6
Subtracting 18 from 20 leaves us with 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 8:
3 goes into 20 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 43737.66
Subtract 18 from 20 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.

Our division results in 43737.66 with a remaining 0.002.
