We're dividing 258206 by 87 
We want to divide 258206 by 87.

Step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 87

Going ahead to step 2:
87 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 87

Advancing to step 3:
The number 87 fits into 258 2 times, leaving a remainder of 84.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 84 after subtracting 174 from 258.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 87

Step 4:
If we divide 842 by 87, we get 9 and a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 783 from 842 leaves us with 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 87

Advancing to step 5:
590 divided by 87 is 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 296.0
Subtract 522 from 590 to get 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 87

On to step 6:
When dividing 686 by 87, we get 7 with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 2967.0
Deduct 609 from 686 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
The number 87 fits into 770 8 times, leaving a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 2967.8
Subtract 696 from 770 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
The number 87 fits into 740 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 2967.88
Subtract 696 from 740 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 2967.88 and a remainder of 0.044.
