Let's divide 124816 by 87
Let's see how many times 87 fits into 124816.

Advancing to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 87

Advancing to step 2:
87 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 87

Going ahead to step 3:
87 can be fit into 124 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 87 from 124, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 87

Moving on to step 4:
87 goes into 378 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 348 from 378 and we're left with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 87

On to step 5:
301 divided by 87 is 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Deduct 261 from 301 and we're left with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 87

Going ahead to step 6:
87 can be fit into 406 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 1434.0
If we take 348 away from 406, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
If we divide 580 by 87, we get 6 and a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 1434.6
Subtract 522 from 580 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
If we divide 580 by 87, we get 6 and a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 1434.66
If we subtract 522 from 580, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 1434.66 and a remainder of 0.058.
