We look at the division of 21659728 by 335 
Our goal is to divide 21659728 by 335.

On to step 1:
335 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 335

Going ahead to step 2:
335 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 335

Going ahead to step 3:
335 can be fit into 216 0 times, resulting in a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Bring next digit (5) of the dividend behind the 216 and repeat the process: 2165 / 335

Moving on to step 4:
335 can be fit into 2165 6 times, resulting in a remainder of 155.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 2010 from 2165 and we're left with 155.
Fetch the next digit (9) from the dividend, attach it to 155 and continue: 1559 / 335

Going ahead to step 5:
335 can be fit into 1559 4 times, resulting in a remainder of 219.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we take 1340 away from 1559, we end up with 219.
Fetch the next digit (7) from the dividend, attach it to 219 and continue: 2197 / 335

Moving on to step 6:
The number 335 fits into 2197 6 times, leaving a remainder of 187.
Use 6 as the next digit of our solution. 
Result so far: 646.0
Subtracting 2010 from 2197 leaves us with 187.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 335

On to step 7:
335 can be fit into 1872 5 times, resulting in a remainder of 197.
The next digit of our result is 5. 
Result so far: 6465.0
If we subtract 1675 from 1872, we get 197.
Take the next digit (8) from the dividend and append it to 197, then repeat: 1978 / 335

Let's proceed to step 8:
335 goes into 1978 5 times with a remainder of 303.
Use 5 as the next digit of our solution. 
Result so far: 64655.0
Deduct 1675 from 1978 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
335 goes into 3030 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 64655.9
Subtract 3015 from 3030 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
If we divide 150 by 335, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 64655.9
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 11:
When dividing 1500 by 335, we get 4 with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 64655.904
If we subtract 1340 from 1500, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
If we divide 1600 by 335, we get 4 and a remainder of 260.
The next digit of our result is 4. 
Result so far: 64655.9044
Subtracting 1340 from 1600 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

After the division, we end up with 64655.9044 and a remainder of 0.0026.
