210688 divided by 87 
We want to figure out the number of times 210688 can be divided by 87.

Step 1:
87 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 87

Going ahead to step 2:
87 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 87

On to step 3:
When dividing 210 by 87, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 36 after subtracting 174 from 210.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 87

On to step 4:
If we divide 366 by 87, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 24.0
If we take 348 away from 366, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 87

Moving on to step 5:
The number 87 fits into 188 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 242.0
The remainder is 14 after subtracting 174 from 188.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 87

Advancing to step 6:
If we divide 148 by 87, we get 1 and a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 2421.0
Deduct 87 from 148 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 7:
The number 87 fits into 610 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 2421.7
Subtract 609 from 610 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 87, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2421.7
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
87 goes into 100 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 2421.701
Subtracting 87 from 100 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
The number 87 fits into 130 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 2421.7011
If we take 87 away from 130, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 2421.7011 and a remainder of 0.00043.
