We're dividing 63864060 by 343 
We want to figure out the number of times 63864060 can be divided by 343.

Step 1:
343 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 343

Let's proceed to step 2:
343 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 343

Advancing to step 3:
The number 343 fits into 638 1 times, leaving a remainder of 295.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 343 from 638 to get 295.
Include the next digit (6) from the dividend after 295, then repeat: 2956 / 343

Advancing to step 4:
The number 343 fits into 2956 8 times, leaving a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 212 after subtracting 2744 from 2956.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 343

Going ahead to step 5:
If we divide 2124 by 343, we get 6 and a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
Deduct 2058 from 2124 and we're left with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 343

Going ahead to step 6:
If we divide 660 by 343, we get 1 and a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1861.0
If we subtract 343 from 660, we get 317.
Grab the next digit (6) from the dividend, add it to 317, then carry on: 3176 / 343

Moving on to step 7:
3176 divided by 343 is 9 with a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 18619.0
The remainder is 89 after subtracting 3087 from 3176.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 343

On to step 8:
When dividing 890 by 343, we get 2 with a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 186192.0
If we take 686 away from 890, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 9:
If we divide 2040 by 343, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 186192.5
The remainder is 325 after subtracting 1715 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 10:
If we divide 3250 by 343, we get 9 and a remainder of 163.
The next digit of our result is 9. 
Result so far: 186192.59
Subtract 3087 from 3250 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 11:
If we divide 1630 by 343, we get 4 and a remainder of 258.
Record the quotient 4 as the next digit in the result. 
Result so far: 186192.594
If we subtract 1372 from 1630, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
The number 343 fits into 2580 7 times, leaving a remainder of 179.
Use 7 as the next digit of our solution. 
Result so far: 186192.5947
Subtract 2401 from 2580 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Let's proceed to step 13:
1790 divided by 343 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 186192.59475
Subtract 1715 from 1790 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
When dividing 750 by 343, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 186192.594752
Subtract 686 from 750 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 15:
343 goes into 640 1 times with a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 186192.5947521
Deduct 343 from 640 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Let's proceed to step 16:
If we divide 2970 by 343, we get 8 and a remainder of 226.
The next digit of our result is 8. 
Result so far: 186192.59475218
If we subtract 2744 from 2970, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final result is 186192.59475218 with a remainder of 2.26e-07.
