We're dividing 888599 by 21 
Let's see how many times 21 fits into 888599.

Let's proceed to step 1:
If we divide 8 by 21, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 21

Step 2:
The number 21 fits into 88 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 88 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 21

On to step 3:
21 goes into 48 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 42.0
The remainder is 6 after subtracting 42 from 48.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 21

Let's proceed to step 4:
When dividing 65 by 21, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 423.0
The remainder is 2 after subtracting 63 from 65.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 21

Going ahead to step 5:
21 can be fit into 29 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 4231.0
If we subtract 21 from 29, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 21

Advancing to step 6:
21 goes into 89 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 42314.0
If we subtract 84 from 89, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 42314.2
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.

Let's proceed to step 8:
When dividing 80 by 21, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 42314.23
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 42314.238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
If we divide 20 by 21, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 42314.238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 42314.23809
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 12:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42314.238095
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.

On to step 13:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 42314.2380952
Subtract 42 from 50 to 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.

Moving on to step 14:
21 goes into 80 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 42314.23809523
Deduct 63 from 80 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 42314.23809523, and the remainder is 1.7e-08.
