Let's divide 21529174 by 336
We want to divide 21529174 by 336.

Going ahead to step 1:
336 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 336

Let's proceed to step 2:
When dividing 21 by 336, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 336

Advancing to step 3:
When dividing 215 by 336, we get 0 with a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Bring next digit (2) of the dividend behind the 215 and repeat the process: 2152 / 336

Going ahead to step 4:
2152 divided by 336 is 6 with a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 2016 from 2152, we get 136.
Append the next digit (9) from the dividend to 136 and continue with: 1369 / 336

Step 5:
336 can be fit into 1369 4 times, resulting in a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 1344 away from 1369, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 336

Step 6:
When dividing 251 by 336, we get 0 with a remainder of 251.
The next digit of our result is 0. 
Result so far: 640.0
If we subtract 0 from 251, we get 251.
Grab the next digit (7) from the dividend, add it to 251, then carry on: 2517 / 336

Step 7:
When dividing 2517 by 336, we get 7 with a remainder of 165.
The next digit of our result is 7. 
Result so far: 6407.0
Deduct 2352 from 2517 and we're left with 165.
Bring next digit (4) of the dividend behind the 165 and repeat the process: 1654 / 336

Let's proceed to step 8:
If we divide 1654 by 336, we get 4 and a remainder of 310.
Record the quotient 4 as the next digit in the result. 
Result so far: 64074.0
The remainder is 310 after subtracting 1344 from 1654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 9:
3100 divided by 336 is 9 with a remainder of 76.
Write down 9 as next digit of the result. 
Result so far: 64074.9
Subtract 3024 from 3100 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
336 goes into 760 2 times with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 64074.92
Deduct 672 from 760 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
336 goes into 880 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 64074.922
Deduct 672 from 880 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The quotient of the division is 64074.922, and the remainder is 0.0208.
