4428488 divided by 285 
We want to divide 4428488 by 285.

Going ahead to step 1:
If we divide 4 by 285, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 285

Going ahead to step 2:
285 can be fit into 44 0 times, resulting in a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Append the next digit (2) from the dividend to 44 and continue with: 442 / 285

On to step 3:
285 goes into 442 1 times with a remainder of 157.
The next digit of our result is 1. 
Result so far: 1.0
If we take 285 away from 442, we end up with 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 285

Let's proceed to step 4:
285 goes into 1578 5 times with a remainder of 153.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 153 after subtracting 1425 from 1578.
Take the next digit (4) from the dividend and append it to 153, then repeat: 1534 / 285

Moving on to step 5:
1534 divided by 285 is 5 with a remainder of 109.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 1425 from 1534 leaves us with 109.
Bring next digit (8) of the dividend behind the 109 and repeat the process: 1098 / 285

On to step 6:
The number 285 fits into 1098 3 times, leaving a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 1553.0
Subtracting 855 from 1098 leaves us with 243.
Grab the next digit (8) from the dividend, add it to 243, then carry on: 2438 / 285

Step 7:
The number 285 fits into 2438 8 times, leaving a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 15538.0
The remainder is 158 after subtracting 2280 from 2438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 8:
When dividing 1580 by 285, we get 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 15538.5
Subtract 1425 from 1580 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
1550 divided by 285 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 15538.55
If we subtract 1425 from 1550, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 15538.55 and a remainder of 0.125.
