We're dividing 63723489 by 343 
Let's see how many times 343 fits into 63723489.

On to step 1:
343 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 343

Going ahead to step 2:
When dividing 63 by 343, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 343

Advancing to step 3:
When dividing 637 by 343, we get 1 with a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 343 from 637 and we're left with 294.
Grab the next digit (2) from the dividend, add it to 294, then carry on: 2942 / 343

On to step 4:
2942 divided by 343 is 8 with a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 2744 from 2942 to get 198.
Include the next digit (3) from the dividend after 198, then repeat: 1983 / 343

Let's proceed to step 5:
343 can be fit into 1983 5 times, resulting in a remainder of 268.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we take 1715 away from 1983, we end up with 268.
Grab the next digit (4) from the dividend, add it to 268, then carry on: 2684 / 343

Moving on to step 6:
343 goes into 2684 7 times with a remainder of 283.
Use 7 as the next digit of our solution. 
Result so far: 1857.0
Subtract 2401 from 2684 to get 283.
Append the next digit (8) from the dividend to 283 and continue with: 2838 / 343

Step 7:
2838 divided by 343 is 8 with a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 18578.0
Subtract 2744 from 2838 to get 94.
Grab the next digit (9) from the dividend, add it to 94, then carry on: 949 / 343

Advancing to step 8:
343 goes into 949 2 times with a remainder of 263.
Use 2 as the next digit of our solution. 
Result so far: 185782.0
If we subtract 686 from 949, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 9:
If we divide 2630 by 343, we get 7 and a remainder of 229.
Use 7 as the next digit of our solution. 
Result so far: 185782.7
If we subtract 2401 from 2630, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 10:
343 goes into 2290 6 times with a remainder of 232.
The next digit of our result is 6. 
Result so far: 185782.76
The remainder is 232 after subtracting 2058 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 11:
When dividing 2320 by 343, we get 6 with a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 185782.766
If we subtract 2058 from 2320, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

The final result is 185782.766 with a remainder of 0.0262.
