We're dividing 221357 by 87 
We want to divide 221357 by 87.

Going ahead to 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 take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 87

Going ahead to step 2:
The number 87 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 87

Step 3:
87 goes into 221 2 times with a remainder of 47.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 174 from 221, we get 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 87

Going ahead to step 4:
473 divided by 87 is 5 with a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 38 after subtracting 435 from 473.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 87

Let's proceed to step 5:
If we divide 385 by 87, we get 4 and a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Subtract 348 from 385 to get 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 87

Step 6:
377 divided by 87 is 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 2544.0
Subtracting 348 from 377 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
When dividing 290 by 87, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 2544.3
Deduct 261 from 290 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
290 divided by 87 is 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 2544.33
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 2544.33 with a remaining 0.029.
