We're dividing 395896 by 21 
We want to figure out the number of times 395896 can be divided by 21.

Let's proceed to step 1:
3 divided by 21 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 21

Moving on to step 2:
The number 21 fits into 39 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 18 after subtracting 21 from 39.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 21

Let's proceed to step 3:
The number 21 fits into 185 8 times, leaving a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 168 from 185, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 21

Advancing to step 4:
21 can be fit into 178 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 188.0
If we take 168 away from 178, we end up with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 21

Going ahead to step 5:
21 goes into 109 5 times with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 1885.0
Subtracting 105 from 109 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 21

Step 6:
21 goes into 46 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 18852.0
Subtract 42 from 46 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 18852.1
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 18852.19
If we subtract 189 from 190, we 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 9:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 18852.19
If we take 0 away from 10, we end up 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.

Let's proceed to step 10:
21 goes into 100 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 18852.1904
If we take 84 away from 100, we end up 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 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 18852.19047
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 18852.190476
Subtract 126 from 130 to get 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 13:
40 divided by 21 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 18852.1904761
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.

On to step 14:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 18852.19047619
If we subtract 189 from 190, we 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.

In conclusion, the division gives 18852.19047619 with a balance of 1e-09.
