We look at the division of 8131445 by 3 
We're looking to find how many times 3 goes into 8131445.

On to step 1:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Advancing to step 2:
3 goes into 21 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 21 away from 21, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Advancing to step 3:
3 divided by 3 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
If we take 3 away from 3, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Going ahead to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 2710.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

On to step 5:
When dividing 14 by 3, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 27104.0
If we take 12 away from 14, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Advancing to step 6:
The number 3 fits into 24 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 271048.0
If we take 24 away from 24, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Let's proceed to step 7:
3 goes into 5 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 2710481.0
If we take 3 away from 5, we end up 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:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 2710481.6
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.

Moving on to step 9:
When dividing 20 by 3, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 2710481.66
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.

The final outcome is 2710481.66, with a leftover of 0.002.
