We divide 348951 by 3
We want to figure out the number of times 348951 can be divided by 3.

Step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 3 from 3 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

On to step 2:
When dividing 4 by 3, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 3 from 4 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

On to step 3:
18 divided by 3 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we subtract 18 from 18, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Moving on to step 4:
3 goes into 9 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1163.0
Subtracting 9 from 9 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

On to step 5:
3 goes into 5 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11631.0
Subtract 3 from 5 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Step 6:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 116317.0
The remainder is 0 after subtracting 21 from 21.
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:
0 divided by 3 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 116317.0
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.

Moving on to step 8:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 116317.0
Subtracting 0 from 0 leaves us 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.

The final result is 116317.0 with a remainder of 0.0.
