83454849 ÷ 343 
We want to divide 83454849 by 343.

On to step 1:
8 divided by 343 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 343

Let's proceed to step 2:
343 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 343

On to step 3:
When dividing 834 by 343, we get 2 with a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 686 from 834, we get 148.
Grab the next digit (5) from the dividend, add it to 148, then carry on: 1485 / 343

Moving on to step 4:
343 can be fit into 1485 4 times, resulting in a remainder of 113.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 1372 from 1485 leaves us with 113.
Grab the next digit (4) from the dividend, add it to 113, then carry on: 1134 / 343

Moving on to step 5:
When dividing 1134 by 343, we get 3 with a remainder of 105.
The next digit of our result is 3. 
Result so far: 243.0
Subtracting 1029 from 1134 leaves us with 105.
Fetch the next digit (8) from the dividend, attach it to 105 and continue: 1058 / 343

Going ahead to step 6:
343 can be fit into 1058 3 times, resulting in a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 2433.0
If we take 1029 away from 1058, we end up with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 343

Moving on to step 7:
294 divided by 343 is 0 with a remainder of 294.
The next digit of our result is 0. 
Result so far: 24330.0
Deduct 0 from 294 and we're left with 294.
Include the next digit (9) from the dividend after 294, then repeat: 2949 / 343

On to step 8:
If we divide 2949 by 343, we get 8 and a remainder of 205.
Write down 8 as next digit of the result. 
Result so far: 243308.0
Subtracting 2744 from 2949 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 9:
2050 divided by 343 is 5 with a remainder of 335.
Use 5 as the next digit of our solution. 
Result so far: 243308.5
If we subtract 1715 from 2050, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 10:
The number 343 fits into 3350 9 times, leaving a remainder of 263.
The next digit of our result is 9. 
Result so far: 243308.59
Subtract 3087 from 3350 to 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.

Let's proceed to step 11:
343 can be fit into 2630 7 times, resulting in a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 243308.597
Subtract 2401 from 2630 to 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.

Moving on to step 12:
When dividing 2290 by 343, we get 6 with a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 243308.5976
Subtract 2058 from 2290 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 13:
The number 343 fits into 2320 6 times, leaving a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 243308.59766
Deduct 2058 from 2320 and we're left with 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 quotient of the division is 243308.59766, and the remainder is 0.000262.
