We're dividing 28402880 by 387 
We want to divide 28402880 by 387.

Advancing to step 1:
The number 387 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 387

Step 2:
When dividing 28 by 387, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 387

Let's proceed to step 3:
387 can be fit into 284 0 times, resulting in a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 284 after subtracting 0 from 284.
Take the next digit (0) from the dividend and append it to 284, then repeat: 2840 / 387

Moving on to step 4:
2840 divided by 387 is 7 with a remainder of 131.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 2709 from 2840 and we're left with 131.
Append the next digit (2) from the dividend to 131 and continue with: 1312 / 387

Going ahead to step 5:
387 can be fit into 1312 3 times, resulting in a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 1161 from 1312, we get 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 387

Let's proceed to step 6:
1518 divided by 387 is 3 with a remainder of 357.
Use 3 as the next digit of our solution. 
Result so far: 733.0
Subtracting 1161 from 1518 leaves us with 357.
Append the next digit (8) from the dividend to 357 and continue with: 3578 / 387

Going ahead to step 7:
When dividing 3578 by 387, we get 9 with a remainder of 95.
Write down 9 as next digit of the result. 
Result so far: 7339.0
The remainder is 95 after subtracting 3483 from 3578.
Include the next digit (0) from the dividend after 95, then repeat: 950 / 387

On to step 8:
When dividing 950 by 387, we get 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 73392.0
Deduct 774 from 950 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 9:
387 goes into 1760 4 times with a remainder of 212.
The next digit of our result is 4. 
Result so far: 73392.4
Subtract 1548 from 1760 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
If we divide 2120 by 387, we get 5 and a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 73392.45
If we subtract 1935 from 2120, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 11:
1850 divided by 387 is 4 with a remainder of 302.
The number 4 becomes the next digit in our result. 
Result so far: 73392.454
Subtract 1548 from 1850 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 12:
387 goes into 3020 7 times with a remainder of 311.
Use 7 as the next digit of our solution. 
Result so far: 73392.4547
Subtract 2709 from 3020 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 13:
When dividing 3110 by 387, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 73392.45478
The remainder is 14 after subtracting 3096 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
140 divided by 387 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 73392.45478
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
If we divide 1400 by 387, we get 3 and a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 73392.4547803
The remainder is 239 after subtracting 1161 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 16:
2390 divided by 387 is 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 73392.45478036
Subtracting 2322 from 2390 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 73392.45478036 with a balance of 6.8e-08.
