We're dividing 345980 by 10 
Let's see how many times 10 fits into 345980.

On to step 1:
3 divided by 10 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 10

Step 2:
If we divide 34 by 10, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 30 from 34 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 10

Going ahead to step 3:
If we divide 45 by 10, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 40 from 45 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 10

Going ahead to step 4:
59 divided by 10 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 345.0
Subtract 50 from 59 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 10

Advancing to step 5:
10 can be fit into 98 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 3459.0
The remainder is 8 after subtracting 90 from 98.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 10

Let's proceed to step 6:
80 divided by 10 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 34598.0
Subtract 80 from 80 to 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:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34598.0
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.

Let's proceed to step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34598.0
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.

After the division, we end up with 34598.0 and a remainder of 0.0.
