Let's divide 865534 by 21
Let's see how many times 21 fits into 865534.

Moving on to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 21

Going ahead to step 2:
21 can be fit into 86 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 84 away from 86, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 21

On to step 3:
21 can be fit into 25 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 21 from 25 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 21

Going ahead to step 4:
21 goes into 45 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 412.0
If we take 42 away from 45, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 21

Advancing to step 5:
When dividing 33 by 21, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 4121.0
If we subtract 21 from 33, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 21

On to step 6:
When dividing 124 by 21, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 41215.0
Subtract 105 from 124 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 41215.9
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 41215.9
Deduct 0 from 10 and we're left 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.

On to step 9:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 41215.904
Deduct 84 from 100 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.

Step 10:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 41215.9047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 41215.90476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 41215.904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 41215.9047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 41215.9047619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 41215.9047619 with a remaining 1e-08.
