64185729 ÷ 336 
Let's see how many times 336 fits into 64185729.

Step 1:
When dividing 6 by 336, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 336

On to step 2:
The number 336 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 336

Moving on to step 3:
The number 336 fits into 641 1 times, leaving a remainder of 305.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 336 from 641 and we're left with 305.
Bring next digit (8) of the dividend behind the 305 and repeat the process: 3058 / 336

Going ahead to step 4:
When dividing 3058 by 336, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3024 from 3058 to get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 336

Let's proceed to step 5:
336 can be fit into 345 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 191.0
Subtracting 336 from 345 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 336

Let's proceed to step 6:
If we divide 97 by 336, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 1910.0
If we take 0 away from 97, we end up with 97.
Fetch the next digit (2) from the dividend, attach it to 97 and continue: 972 / 336

Going ahead to step 7:
When dividing 972 by 336, we get 2 with a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 19102.0
Subtracting 672 from 972 leaves us with 300.
Grab the next digit (9) from the dividend, add it to 300, then carry on: 3009 / 336

Let's proceed to step 8:
If we divide 3009 by 336, we get 8 and a remainder of 321.
Put 8 as the next digit of the answer. 
Result so far: 191028.0
The remainder is 321 after subtracting 2688 from 3009.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 9:
3210 divided by 336 is 9 with a remainder of 186.
The number 9 becomes the next digit in our result. 
Result so far: 191028.9
Subtracting 3024 from 3210 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
336 can be fit into 1860 5 times, resulting in a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 191028.95
The remainder is 180 after subtracting 1680 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 11:
When dividing 1800 by 336, we get 5 with a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 191028.955
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 191028.955 with a remainder of 0.012.
