We're dividing 854536 by 21 
Our goal is to divide 854536 by 21.

Going ahead to step 1:
The number 21 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 21

Let's proceed to step 2:
The number 21 fits into 85 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 85 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 21

On to step 3:
The number 21 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 14 to get 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 21

On to step 4:
If we divide 145 by 21, we get 6 and a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 406.0
Deduct 126 from 145 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 21

On to step 5:
193 divided by 21 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 4069.0
If we subtract 189 from 193, we get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 21

Going ahead to step 6:
46 divided by 21 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 40692.0
Subtracting 42 from 46 leaves us 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.

Going ahead 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: 40692.1
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.

Let's proceed to step 8:
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: 40692.19
If we take 189 away from 190, we end up 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.

Let's proceed to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 40692.19
Subtracting 0 from 10 leaves us 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.

Step 10:
100 divided by 21 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 40692.1904
Subtracting 84 from 100 leaves us 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.

Going ahead to step 11:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 40692.19047
Deduct 147 from 160 and we're left 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.

On to step 12:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 40692.190476
Subtracting 126 from 130 leaves us 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.

Going ahead to step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 40692.1904761
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.

Advancing to step 14:
When dividing 190 by 21, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 40692.19047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 40692.19047619, and the remainder is 1e-09.
