We divide 60480286 by 4
Let's see how many times 4 fits into 60480286.

Going ahead to step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 4 from 6 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Advancing to step 2:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 20 from 20, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 4

On to step 3:
When dividing 4 by 4, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
If we subtract 4 from 4, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 4

Advancing to step 4:
8 divided by 4 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1512.0
Subtracting 8 from 8 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 4

Let's proceed to step 5:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15120.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 4

Moving on to step 6:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 151200.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 4

Let's proceed to step 7:
4 goes into 28 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1512007.0
The remainder is 0 after subtracting 28 from 28.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Advancing to step 8:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 15120071.0
Subtracting 4 from 6 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15120071.5
Subtract 20 from 20 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 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15120071.5
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.

Advancing to step 11:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15120071.5
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.

The quotient of the division is 15120071.5, and the remainder is 0.0.
