We're dividing 15023900 by 28 
We're looking to find how many times 28 goes into 15023900.

Step 1:
28 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 28

Advancing to step 2:
28 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 28

Step 3:
The number 28 fits into 150 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 140 from 150 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 28

On to step 4:
When dividing 102 by 28, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 84 from 102 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 28

Let's proceed to step 5:
If we divide 183 by 28, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 536.0
The remainder is 15 after subtracting 168 from 183.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 28

Step 6:
When dividing 159 by 28, we get 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 5365.0
Subtracting 140 from 159 leaves us with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 28

Let's proceed to step 7:
190 divided by 28 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 53656.0
If we subtract 168 from 190, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 28

Let's proceed to step 8:
220 divided by 28 is 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 536567.0
If we subtract 196 from 220, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 28, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 536567.8
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 536567.85
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 536567.857
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 536567.8571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 536567.85714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 536567.857142
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
If we divide 240 by 28, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 536567.8571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
When dividing 160 by 28, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 536567.85714285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 536567.85714285, and the remainder is 2e-08.
