Let's divide 215566 by 75
Our goal is to divide 215566 by 75.

Advancing to step 1:
The number 75 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 75

Let's proceed to step 2:
If we divide 21 by 75, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 75

Moving on to step 3:
If we divide 215 by 75, we get 2 and a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 150 from 215 to get 65.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 75

Let's proceed to step 4:
655 divided by 75 is 8 with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 600 from 655 and we're left with 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 75

Moving on to step 5:
75 goes into 556 7 times with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 287.0
Subtracting 525 from 556 leaves us with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 75

Going ahead to step 6:
316 divided by 75 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 2874.0
Deduct 300 from 316 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
75 can be fit into 160 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 2874.2
Subtracting 150 from 160 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 75, we get 1 and a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 2874.21
Subtracting 75 from 100 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The next digit of our result is 3. 
Result so far: 2874.213
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
75 can be fit into 250 3 times, resulting in a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 2874.2133
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 2874.2133 with a remainder of 0.00025.
