348973 ÷ 3 
Our goal is to divide 348973 by 3.

Let's proceed to step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 3 from 3 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

Let's proceed to step 2:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 11.0
If we take 3 away from 4, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Going ahead to step 3:
18 divided by 3 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 18 from 18, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 3

Moving on to step 4:
The number 3 fits into 9 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 1163.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Advancing to step 5:
If we divide 7 by 3, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 11632.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 3

On to step 6:
3 goes into 13 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 116324.0
If we take 12 away from 13, 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:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 116324.3
If we subtract 9 from 10, we 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:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 116324.33
Deduct 9 from 10 and we're left 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.

After the division, we end up with 116324.33 and a remainder of 0.001.
