63873878 divided by 343 
Our goal is to divide 63873878 by 343.

Moving on to step 1:
When dividing 6 by 343, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 343

On to step 2:
If we divide 63 by 343, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 343

Moving on to step 3:
343 goes into 638 1 times with 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 (7) from the dividend after 295, then repeat: 2957 / 343

Step 4:
If we divide 2957 by 343, we get 8 and a remainder of 213.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 2744 from 2957 and we're left with 213.
Bring next digit (3) of the dividend behind the 213 and repeat the process: 2133 / 343

Advancing to step 5:
When dividing 2133 by 343, we get 6 with a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 186.0
Subtracting 2058 from 2133 leaves us with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 343

Advancing to step 6:
When dividing 758 by 343, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 1862.0
The remainder is 72 after subtracting 686 from 758.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 343

On to step 7:
343 goes into 727 2 times with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 18622.0
If we subtract 686 from 727, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 343

Step 8:
418 divided by 343 is 1 with a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 186221.0
If we take 343 away from 418, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
343 goes into 750 2 times with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 186221.2
The remainder is 64 after subtracting 686 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
When dividing 640 by 343, we get 1 with a remainder of 297.
Write down 1 as next digit of the result. 
Result so far: 186221.21
If we take 343 away from 640, we end up 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.

On to step 11:
If we divide 2970 by 343, we get 8 and a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 186221.218
Deduct 2744 from 2970 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 12:
The number 343 fits into 2260 6 times, leaving a remainder of 202.
The number 6 becomes the next digit in our result. 
Result so far: 186221.2186
Deduct 2058 from 2260 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 13:
343 can be fit into 2020 5 times, resulting in a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 186221.21865
The remainder is 305 after subtracting 1715 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 14:
3050 divided by 343 is 8 with a remainder of 306.
Put 8 as the next digit of the answer. 
Result so far: 186221.218658
The remainder is 306 after subtracting 2744 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 15:
If we divide 3060 by 343, we get 8 and a remainder of 316.
Put 8 as the next digit of the answer. 
Result so far: 186221.2186588
Deduct 2744 from 3060 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Our division results in 186221.2186588 with a remaining 3.16e-06.
