Let's divide 881684 by 21
Let's see how many times 21 fits into 881684.

Advancing to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 21

Moving on to step 2:
The number 21 fits into 88 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 84 from 88, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 21

Step 3:
21 goes into 41 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 21 from 41 leaves us with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 21

Let's proceed to step 4:
206 divided by 21 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 419.0
If we take 189 away from 206, we end up with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 21

Going ahead to step 5:
The number 21 fits into 178 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 4198.0
Deduct 168 from 178 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 21

On to step 6:
The number 21 fits into 104 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 41984.0
If we subtract 84 from 104, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 41984.9
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
21 goes into 110 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 41984.95
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
21 goes into 50 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 41984.952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 41984.9523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 41984.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 41984.95238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
When dividing 200 by 21, we get 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 41984.9523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 41984.95238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 41984.95238095, with a leftover of 5e-09.
