We divide 280487 by 73
We want to figure out the number of times 280487 can be divided by 73.

On to step 1:
2 divided by 73 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 73

Step 2:
If we divide 28 by 73, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 73

Let's proceed to step 3:
73 can be fit into 280 3 times, resulting in a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 219 from 280 to get 61.
Take the next digit (4) from the dividend and append it to 61, then repeat: 614 / 73

On to step 4:
When dividing 614 by 73, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we subtract 584 from 614, we get 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 73

On to step 5:
When dividing 308 by 73, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 384.0
Subtracting 292 from 308 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 73

Going ahead to step 6:
If we divide 167 by 73, we get 2 and a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 3842.0
Deduct 146 from 167 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 73 fits into 210 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 3842.2
If we subtract 146 from 210, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 8:
If we divide 640 by 73, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 3842.28
Subtract 584 from 640 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
The number 73 fits into 560 7 times, leaving a remainder of 49.
The next digit of our result is 7. 
Result so far: 3842.287
Subtract 511 from 560 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
73 goes into 490 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 3842.2876
The remainder is 52 after subtracting 438 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
520 divided by 73 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 3842.28767
Deduct 511 from 520 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
90 divided by 73 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 3842.287671
Deduct 73 from 90 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
If we divide 170 by 73, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3842.2876712
If we subtract 146 from 170, 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.

Going ahead to step 14:
73 can be fit into 240 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3842.28767123
Deduct 219 from 240 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 3842.28767123 with a remaining 2.1e-08.
