We're dividing 258471 by 73 
We want to divide 258471 by 73.

On to step 1:
73 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 73

Going ahead to step 2:
25 divided by 73 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 73

Going ahead to step 3:
73 goes into 258 3 times with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 219 from 258 leaves us with 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 73

Moving on to step 4:
73 can be fit into 394 5 times, resulting in a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 365 from 394 and we're left with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 73

Let's proceed to step 5:
73 goes into 297 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 354.0
Subtracting 292 from 297 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 73

Moving on to step 6:
73 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 3540.0
Deduct 0 from 51 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 73, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 3540.6
Deduct 438 from 510 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
720 divided by 73 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 3540.69
Deduct 657 from 720 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
630 divided by 73 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 3540.698
Subtracting 584 from 630 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
73 goes into 460 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 3540.6986
Subtracting 438 from 460 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
If we divide 220 by 73, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3540.69863
If we subtract 219 from 220, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
10 divided by 73 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3540.69863
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 73 fits into 100 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 3540.6986301
Subtract 73 from 100 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
73 goes into 270 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 3540.69863013
The remainder is 51 after subtracting 219 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 3540.69863013 and a remainder of 5.1e-08.
