We divide 124325 by 87
Our goal is to divide 124325 by 87.

Step 1:
87 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 87

Let's proceed to step 2:
87 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 87

Moving on to step 3:
87 goes into 124 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 87 from 124 and we're left with 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 87

Moving on to step 4:
87 goes into 373 4 times with a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 25 after subtracting 348 from 373.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 87

Advancing to step 5:
252 divided by 87 is 2 with a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
Deduct 174 from 252 and we're left with 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 87

Step 6:
87 goes into 785 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1429.0
The remainder is 2 after subtracting 783 from 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 87 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1429.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 87, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 1429.02
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
When dividing 260 by 87, we get 2 with a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 1429.022
If we subtract 174 from 260, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 1429.022 with a remainder of 0.0086.
