143379 divided by 3 
Let's see how many times 3 fits into 143379.

Advancing to step 1:
3 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 3

Step 2:
14 divided by 3 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 12 from 14, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Going ahead to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 21 from 23 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 4:
When dividing 23 by 3, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 477.0
Deduct 21 from 23 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 3

Moving on to step 5:
The number 3 fits into 27 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4779.0
The remainder is 0 after subtracting 27 from 27.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Moving on to step 6:
3 goes into 9 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 47793.0
If we subtract 9 from 9, 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.

Advancing to step 7:
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: 47793.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 47793.0
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.

The final outcome is 47793.0, with a leftover of 0.0.
