64209852 ÷ 353 
We're looking to find how many times 353 goes into 64209852.

Let's proceed to step 1:
When dividing 6 by 353, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 353

Moving on to step 2:
353 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 353

Let's proceed to step 3:
The number 353 fits into 642 1 times, leaving a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 289 after subtracting 353 from 642.
Fetch the next digit (0) from the dividend, attach it to 289 and continue: 2890 / 353

Let's proceed to step 4:
2890 divided by 353 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 66 after subtracting 2824 from 2890.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 353

Going ahead to step 5:
669 divided by 353 is 1 with a remainder of 316.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Subtracting 353 from 669 leaves us with 316.
Include the next digit (8) from the dividend after 316, then repeat: 3168 / 353

Advancing to step 6:
If we divide 3168 by 353, we get 8 and a remainder of 344.
The number 8 becomes the next digit in our result. 
Result so far: 1818.0
If we take 2824 away from 3168, we end up with 344.
Include the next digit (5) from the dividend after 344, then repeat: 3445 / 353

Let's proceed to step 7:
The number 353 fits into 3445 9 times, leaving a remainder of 268.
Write down 9 as next digit of the result. 
Result so far: 18189.0
Subtracting 3177 from 3445 leaves us with 268.
Bring next digit (2) of the dividend behind the 268 and repeat the process: 2682 / 353

Step 8:
If we divide 2682 by 353, we get 7 and a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 181897.0
If we take 2471 away from 2682, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
The number 353 fits into 2110 5 times, leaving a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 181897.5
The remainder is 345 after subtracting 1765 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 10:
3450 divided by 353 is 9 with a remainder of 273.
Record the quotient 9 as the next digit in the result. 
Result so far: 181897.59
The remainder is 273 after subtracting 3177 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 11:
If we divide 2730 by 353, we get 7 and a remainder of 259.
The next digit of our result is 7. 
Result so far: 181897.597
Deduct 2471 from 2730 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 12:
If we divide 2590 by 353, we get 7 and a remainder of 119.
The number 7 becomes the next digit in our result. 
Result so far: 181897.5977
Deduct 2471 from 2590 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

After the division, we end up with 181897.5977 and a remainder of 0.00119.
