99887249 divided by 343 
Our goal is to divide 99887249 by 343.

Moving on to step 1:
343 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 343

Step 2:
343 goes into 99 0 times with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (8) from the dividend, attach it to 99 and continue: 998 / 343

Let's proceed to step 3:
998 divided by 343 is 2 with a remainder of 312.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 686 from 998 and we're left with 312.
Bring next digit (8) of the dividend behind the 312 and repeat the process: 3128 / 343

Let's proceed to step 4:
3128 divided by 343 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 3087 from 3128, we get 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 343

Going ahead to step 5:
When dividing 417 by 343, we get 1 with a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Subtract 343 from 417 to get 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 343

Going ahead to step 6:
742 divided by 343 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 2912.0
Subtracting 686 from 742 leaves us with 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 343

Let's proceed to step 7:
The number 343 fits into 564 1 times, leaving a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 29121.0
The remainder is 221 after subtracting 343 from 564.
Take the next digit (9) from the dividend and append it to 221, then repeat: 2219 / 343

Moving on to step 8:
343 can be fit into 2219 6 times, resulting in a remainder of 161.
The number 6 becomes the next digit in our result. 
Result so far: 291216.0
The remainder is 161 after subtracting 2058 from 2219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 9:
343 goes into 1610 4 times with a remainder of 238.
The next digit of our result is 4. 
Result so far: 291216.4
The remainder is 238 after subtracting 1372 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 10:
When dividing 2380 by 343, we get 6 with a remainder of 322.
The next digit of our result is 6. 
Result so far: 291216.46
Deduct 2058 from 2380 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 11:
343 can be fit into 3220 9 times, resulting in a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 291216.469
Subtracting 3087 from 3220 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 12:
343 can be fit into 1330 3 times, resulting in a remainder of 301.
The number 3 becomes the next digit in our result. 
Result so far: 291216.4693
If we take 1029 away from 1330, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 13:
343 goes into 3010 8 times with a remainder of 266.
Write down 8 as next digit of the result. 
Result so far: 291216.46938
Deduct 2744 from 3010 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 14:
343 can be fit into 2660 7 times, resulting in a remainder of 259.
Use 7 as the next digit of our solution. 
Result so far: 291216.469387
Deduct 2401 from 2660 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 15:
343 can be fit into 2590 7 times, resulting in a remainder of 189.
Write down 7 as next digit of the result. 
Result so far: 291216.4693877
Deduct 2401 from 2590 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

The final outcome is 291216.4693877, with a leftover of 1.89e-06.
