We're dividing 64403427 by 343 
We're looking to find how many times 343 goes into 64403427.

Let's proceed to step 1:
6 divided by 343 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 343

Going ahead to step 2:
343 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 343

Step 3:
343 can be fit into 644 1 times, resulting in a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 343 from 644, we get 301.
Append the next digit (0) from the dividend to 301 and continue with: 3010 / 343

On to step 4:
If we divide 3010 by 343, we get 8 and a remainder of 266.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 266 after subtracting 2744 from 3010.
Append the next digit (3) from the dividend to 266 and continue with: 2663 / 343

Moving on to step 5:
2663 divided by 343 is 7 with a remainder of 262.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Subtract 2401 from 2663 to get 262.
Fetch the next digit (4) from the dividend, attach it to 262 and continue: 2624 / 343

Moving on to step 6:
343 can be fit into 2624 7 times, resulting in a remainder of 223.
The number 7 becomes the next digit in our result. 
Result so far: 1877.0
If we take 2401 away from 2624, we end up with 223.
Grab the next digit (2) from the dividend, add it to 223, then carry on: 2232 / 343

On to step 7:
If we divide 2232 by 343, we get 6 and a remainder of 174.
Record the quotient 6 as the next digit in the result. 
Result so far: 18776.0
Subtract 2058 from 2232 to get 174.
Bring next digit (7) of the dividend behind the 174 and repeat the process: 1747 / 343

On to step 8:
343 can be fit into 1747 5 times, resulting in a remainder of 32.
The next digit of our result is 5. 
Result so far: 187765.0
The remainder is 32 after subtracting 1715 from 1747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
343 can be fit into 320 0 times, resulting in a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 187765.0
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
The number 343 fits into 3200 9 times, leaving a remainder of 113.
The next digit of our result is 9. 
Result so far: 187765.09
If we take 3087 away from 3200, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 11:
1130 divided by 343 is 3 with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 187765.093
Subtract 1029 from 1130 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 12:
The number 343 fits into 1010 2 times, leaving a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 187765.0932
Deduct 686 from 1010 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 13:
343 can be fit into 3240 9 times, resulting in a remainder of 153.
Record the quotient 9 as the next digit in the result. 
Result so far: 187765.09329
Deduct 3087 from 3240 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 14:
1530 divided by 343 is 4 with a remainder of 158.
The next digit of our result is 4. 
Result so far: 187765.093294
Subtracting 1372 from 1530 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 15:
When dividing 1580 by 343, we get 4 with a remainder of 208.
The next digit of our result is 4. 
Result so far: 187765.0932944
If we take 1372 away from 1580, we end up 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 final outcome is 187765.0932944, with a leftover of 2.08e-06.
