Let's divide 21224868 by 987
Our goal is to divide 21224868 by 987.

Going ahead to step 1:
The number 987 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 987

Step 2:
If we divide 21 by 987, we get 0 and 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.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 987

Going ahead to step 3:
If we divide 212 by 987, we get 0 and a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Include the next digit (2) from the dividend after 212, then repeat: 2122 / 987

Let's proceed to step 4:
987 can be fit into 2122 2 times, resulting in a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1974 from 2122 and we're left with 148.
Bring next digit (4) of the dividend behind the 148 and repeat the process: 1484 / 987

On to step 5:
987 can be fit into 1484 1 times, resulting in a remainder of 497.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 987 from 1484 leaves us with 497.
Append the next digit (8) from the dividend to 497 and continue with: 4978 / 987

Going ahead to step 6:
When dividing 4978 by 987, we get 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Deduct 4935 from 4978 and we're left with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 987

On to step 7:
987 goes into 436 0 times with a remainder of 436.
The next digit of our result is 0. 
Result so far: 2150.0
The remainder is 436 after subtracting 0 from 436.
Bring next digit (8) of the dividend behind the 436 and repeat the process: 4368 / 987

Let's proceed to step 8:
987 goes into 4368 4 times with a remainder of 420.
Use 4 as the next digit of our solution. 
Result so far: 21504.0
Subtracting 3948 from 4368 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 9:
987 can be fit into 4200 4 times, resulting in a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 21504.4
Subtract 3948 from 4200 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 10:
If we divide 2520 by 987, we get 2 and a remainder of 546.
Record the quotient 2 as the next digit in the result. 
Result so far: 21504.42
Subtracting 1974 from 2520 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 11:
987 goes into 5460 5 times with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 21504.425
The remainder is 525 after subtracting 4935 from 5460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 12:
The number 987 fits into 5250 5 times, leaving a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 21504.4255
The remainder is 315 after subtracting 4935 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 21504.4255 with a remainder of 0.00315.
