We look at the division of 15440228 by 428 
We're looking to find how many times 428 goes into 15440228.

Step 1:
1 divided by 428 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 428

Moving on to step 2:
The number 428 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 428

Let's proceed to step 3:
The number 428 fits into 154 0 times, leaving a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Grab the next digit (4) from the dividend, add it to 154, then carry on: 1544 / 428

On to step 4:
When dividing 1544 by 428, we get 3 with a remainder of 260.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 1284 from 1544 to get 260.
Fetch the next digit (0) from the dividend, attach it to 260 and continue: 2600 / 428

Going ahead to step 5:
When dividing 2600 by 428, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 2568 from 2600 to get 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 428

Step 6:
428 can be fit into 322 0 times, resulting in a remainder of 322.
Use 0 as the next digit of our solution. 
Result so far: 360.0
Deduct 0 from 322 and we're left with 322.
Append the next digit (2) from the dividend to 322 and continue with: 3222 / 428

Moving on to step 7:
The number 428 fits into 3222 7 times, leaving a remainder of 226.
Use 7 as the next digit of our solution. 
Result so far: 3607.0
Deduct 2996 from 3222 and we're left with 226.
Grab the next digit (8) from the dividend, add it to 226, then carry on: 2268 / 428

Going ahead to step 8:
If we divide 2268 by 428, we get 5 and a remainder of 128.
Put 5 as the next digit of the answer. 
Result so far: 36075.0
If we subtract 2140 from 2268, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 9:
The number 428 fits into 1280 2 times, leaving a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 36075.2
Deduct 856 from 1280 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 10:
4240 divided by 428 is 9 with a remainder of 388.
Use 9 as the next digit of our solution. 
Result so far: 36075.29
Deduct 3852 from 4240 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
The number 428 fits into 3880 9 times, leaving a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 36075.299
If we subtract 3852 from 3880, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 36075.299 with a remainder of 0.0028.
