We're dividing 18706519 by 343 
We want to figure out the number of times 18706519 can be divided by 343.

Let's proceed to step 1:
1 divided by 343 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 343

Moving on to step 2:
When dividing 18 by 343, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 343

Going ahead to step 3:
343 can be fit into 187 0 times, resulting in a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 187 leaves us with 187.
Include the next digit (0) from the dividend after 187, then repeat: 1870 / 343

Going ahead to step 4:
343 goes into 1870 5 times with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 1715 away from 1870, we end up with 155.
Grab the next digit (6) from the dividend, add it to 155, then carry on: 1556 / 343

On to step 5:
343 goes into 1556 4 times with a remainder of 184.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we subtract 1372 from 1556, we get 184.
Grab the next digit (5) from the dividend, add it to 184, then carry on: 1845 / 343

Moving on to step 6:
When dividing 1845 by 343, we get 5 with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 545.0
The remainder is 130 after subtracting 1715 from 1845.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 343

Advancing to step 7:
When dividing 1301 by 343, we get 3 with a remainder of 272.
The number 3 becomes the next digit in our result. 
Result so far: 5453.0
Deduct 1029 from 1301 and we're left with 272.
Bring next digit (9) of the dividend behind the 272 and repeat the process: 2729 / 343

Moving on to step 8:
2729 divided by 343 is 7 with a remainder of 328.
Put 7 as the next digit of the answer. 
Result so far: 54537.0
If we subtract 2401 from 2729, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 9:
The number 343 fits into 3280 9 times, leaving a remainder of 193.
The next digit of our result is 9. 
Result so far: 54537.9
Subtracting 3087 from 3280 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 10:
The number 343 fits into 1930 5 times, leaving a remainder of 215.
The next digit of our result is 5. 
Result so far: 54537.95
Subtract 1715 from 1930 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 11:
If we divide 2150 by 343, we get 6 and a remainder of 92.
The next digit of our result is 6. 
Result so far: 54537.956
Subtract 2058 from 2150 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 12:
The number 343 fits into 920 2 times, leaving a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 54537.9562
The remainder is 234 after subtracting 686 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 13:
When dividing 2340 by 343, we get 6 with a remainder of 282.
The number 6 becomes the next digit in our result. 
Result so far: 54537.95626
If we take 2058 away from 2340, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 14:
343 goes into 2820 8 times with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 54537.956268
If we take 2744 away from 2820, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 15:
The number 343 fits into 760 2 times, leaving a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 54537.9562682
If we take 686 away from 760, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 16:
343 can be fit into 740 2 times, resulting in a remainder of 54.
The next digit of our result is 2. 
Result so far: 54537.95626822
Deduct 686 from 740 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 54537.95626822 with a remaining 5.4e-08.
