390958 ÷ 4 
We want to divide 390958 by 4.

On to step 1:
When dividing 3 by 4, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

On to step 2:
If we divide 39 by 4, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 36 away from 39, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 4

Advancing to step 3:
4 goes into 30 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 2 after subtracting 28 from 30.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 4

Let's proceed to step 4:
When dividing 29 by 4, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 977.0
Subtracting 28 from 29 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 4

Step 5:
4 can be fit into 15 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 9773.0
Subtract 12 from 15 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

Going ahead to step 6:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 97739.0
If we subtract 36 from 38, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 97739.5
The remainder is 0 after subtracting 20 from 20.
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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 97739.5
Deduct 0 from 0 and we're left 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 9:
0 divided by 4 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 97739.5
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.

In conclusion, the division gives 97739.5 with a balance of 0.0.
