486160 divided by 4 
We want to figure out the number of times 486160 can be divided by 4.

Step 1:
When dividing 4 by 4, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 4 from 4 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 4

Let's proceed to step 2:
4 can be fit into 8 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Going ahead to step 3:
The number 4 fits into 6 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 121.0
The remainder is 2 after subtracting 4 from 6.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

On to step 4:
4 can be fit into 21 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 1215.0
Subtract 20 from 21 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 4

Advancing to step 5:
If we divide 16 by 4, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 12154.0
If we subtract 16 from 16, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Going ahead to step 6:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 121540.0
Subtract 0 from 0 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.

Let's proceed to step 7:
4 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 121540.0
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.

Advancing to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 121540.0
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 121540.0 with a balance of 0.0.
