Let's divide 124830 by 87
We're looking to find how many times 87 goes into 124830.

Advancing to step 1:
1 divided by 87 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 87

On to step 2:
87 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 87

Going ahead to step 3:
When dividing 124 by 87, we get 1 with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 37 after subtracting 87 from 124.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 87

Moving on to step 4:
If we divide 378 by 87, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 30 after subtracting 348 from 378.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 87

Going ahead to step 5:
The number 87 fits into 303 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 143.0
If we subtract 261 from 303, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 87

Step 6:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1434.0
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
87 can be fit into 720 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 1434.8
Deduct 696 from 720 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
240 divided by 87 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 1434.82
Subtract 174 from 240 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
87 goes into 660 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1434.827
The remainder is 51 after subtracting 609 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
If we divide 510 by 87, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 1434.8275
Deduct 435 from 510 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
When dividing 750 by 87, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 1434.82758
Deduct 696 from 750 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
540 divided by 87 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1434.827586
Subtracting 522 from 540 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
The number 87 fits into 180 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1434.8275862
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
The number 87 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1434.8275862
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 1434.8275862 and a remainder of 6e-08.
