We're dividing 15023420 by 802 
We're looking to find how many times 802 goes into 15023420.

Moving on to step 1:
The number 802 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 802

Going ahead to step 2:
When dividing 15 by 802, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 802

On to step 3:
150 divided by 802 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 150 after subtracting 0 from 150.
Append the next digit (2) from the dividend to 150 and continue with: 1502 / 802

Going ahead to step 4:
When dividing 1502 by 802, we get 1 with a remainder of 700.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 802 from 1502 to get 700.
Bring next digit (3) of the dividend behind the 700 and repeat the process: 7003 / 802

Let's proceed to step 5:
When dividing 7003 by 802, we get 8 with a remainder of 587.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 6416 from 7003 leaves us with 587.
Bring next digit (4) of the dividend behind the 587 and repeat the process: 5874 / 802

Moving on to step 6:
When dividing 5874 by 802, we get 7 with a remainder of 260.
The next digit of our result is 7. 
Result so far: 187.0
Subtracting 5614 from 5874 leaves us with 260.
Take the next digit (2) from the dividend and append it to 260, then repeat: 2602 / 802

Moving on to step 7:
When dividing 2602 by 802, we get 3 with a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 1873.0
Subtracting 2406 from 2602 leaves us with 196.
Grab the next digit (0) from the dividend, add it to 196, then carry on: 1960 / 802

Moving on to step 8:
When dividing 1960 by 802, we get 2 with a remainder of 356.
Use 2 as the next digit of our solution. 
Result so far: 18732.0
If we subtract 1604 from 1960, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 9:
802 can be fit into 3560 4 times, resulting in a remainder of 352.
The next digit of our result is 4. 
Result so far: 18732.4
Deduct 3208 from 3560 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 10:
When dividing 3520 by 802, we get 4 with a remainder of 312.
The number 4 becomes the next digit in our result. 
Result so far: 18732.44
Subtracting 3208 from 3520 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 18732.44 with a balance of 0.312.
