Let's divide 210156 by 87
Our goal is to divide 210156 by 87.

Step 1:
87 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 87

Moving on to step 2:
21 divided by 87 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 87

Let's proceed to step 3:
The number 87 fits into 210 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 174 from 210, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 87

Advancing to step 4:
The number 87 fits into 361 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 348 from 361, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 87

Step 5:
87 goes into 135 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 241.0
Subtracting 87 from 135 leaves us with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 87

Let's proceed to step 6:
486 divided by 87 is 5 with a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 2415.0
If we subtract 435 from 486, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
87 goes into 510 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 2415.5
Subtract 435 from 510 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 8:
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: 2415.58
The remainder is 54 after subtracting 696 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
87 goes into 540 6 times with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 2415.586
Subtract 522 from 540 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 87 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2415.5862
Deduct 174 from 180 and we're left 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.

Moving on to step 11:
87 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2415.5862
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.

Step 12:
If we divide 600 by 87, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 2415.586206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
If we divide 780 by 87, we get 8 and a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 2415.5862068
The remainder is 84 after subtracting 696 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 14:
If we divide 840 by 87, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 2415.58620689
Subtract 783 from 840 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 2415.58620689 with a remaining 5.7e-08.
