We look at the division of 21204154 by 335 
Our goal is to divide 21204154 by 335.

On to step 1:
335 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 335

Going ahead to step 2:
The number 335 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 335

Advancing to step 3:
If we divide 212 by 335, we get 0 and a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Bring next digit (0) of the dividend behind the 212 and repeat the process: 2120 / 335

Let's proceed to step 4:
The number 335 fits into 2120 6 times, leaving a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 2010 from 2120 and we're left with 110.
Fetch the next digit (4) from the dividend, attach it to 110 and continue: 1104 / 335

Let's proceed to step 5:
335 can be fit into 1104 3 times, resulting in a remainder of 99.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
The remainder is 99 after subtracting 1005 from 1104.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 335

Going ahead to step 6:
When dividing 991 by 335, we get 2 with a remainder of 321.
Use 2 as the next digit of our solution. 
Result so far: 632.0
If we subtract 670 from 991, we get 321.
Append the next digit (5) from the dividend to 321 and continue with: 3215 / 335

Let's proceed to step 7:
335 can be fit into 3215 9 times, resulting in a remainder of 200.
Put 9 as the next digit of the answer. 
Result so far: 6329.0
Subtracting 3015 from 3215 leaves us with 200.
Grab the next digit (4) from the dividend, add it to 200, then carry on: 2004 / 335

On to step 8:
When dividing 2004 by 335, we get 5 with a remainder of 329.
The number 5 becomes the next digit in our result. 
Result so far: 63295.0
If we subtract 1675 from 2004, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 9:
When dividing 3290 by 335, we get 9 with a remainder of 275.
Record the quotient 9 as the next digit in the result. 
Result so far: 63295.9
Subtract 3015 from 3290 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
335 goes into 2750 8 times with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 63295.98
Subtract 2680 from 2750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
335 goes into 700 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 63295.982
Deduct 670 from 700 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
335 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 63295.982
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
3000 divided by 335 is 8 with a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 63295.98208
If we subtract 2680 from 3000, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 14:
335 goes into 3200 9 times with a remainder of 185.
Write down 9 as next digit of the result. 
Result so far: 63295.982089
Subtract 3015 from 3200 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 15:
When dividing 1850 by 335, we get 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 63295.9820895
If we subtract 1675 from 1850, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 16:
The number 335 fits into 1750 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 63295.98208955
Subtract 1675 from 1750 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 63295.98208955, and the remainder is 7.5e-08.
