We're dividing 43958 by 10 
Let's see how many times 10 fits into 43958.

Advancing to step 1:
4 divided by 10 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 10

Going ahead to step 2:
10 can be fit into 43 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 40 away from 43, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 10

Going ahead to step 3:
If we divide 39 by 10, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 30 from 39 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 10

On to step 4:
When dividing 95 by 10, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 90 from 95 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 10

Step 5:
If we divide 58 by 10, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 4395.0
If we take 50 away from 58, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 6:
10 goes into 80 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4395.8
If we subtract 80 from 80, 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.

Going ahead to step 7:
When dividing 0 by 10, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4395.8
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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4395.8
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.

In conclusion, the division gives 4395.8 with a balance of 0.0.
