24512681 divided by 343 
The aim is to understand the frequency of 343 in 24512681.

Step 1:
If we divide 2 by 343, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 343

Let's proceed to step 2:
When dividing 24 by 343, we get 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 343

On to step 3:
When dividing 245 by 343, we get 0 with a remainder of 245.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 245, we get 245.
Grab the next digit (1) from the dividend, add it to 245, then carry on: 2451 / 343

Let's proceed to step 4:
2451 divided by 343 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 2401 away from 2451, we end up with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 343

Step 5:
When dividing 502 by 343, we get 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtract 343 from 502 to get 159.
Bring next digit (6) of the dividend behind the 159 and repeat the process: 1596 / 343

Step 6:
343 can be fit into 1596 4 times, resulting in a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 714.0
Subtracting 1372 from 1596 leaves us with 224.
Bring next digit (8) of the dividend behind the 224 and repeat the process: 2248 / 343

On to step 7:
When dividing 2248 by 343, we get 6 with a remainder of 190.
Write down 6 as next digit of the result. 
Result so far: 7146.0
Subtracting 2058 from 2248 leaves us with 190.
Bring next digit (1) of the dividend behind the 190 and repeat the process: 1901 / 343

Going ahead to step 8:
343 goes into 1901 5 times with a remainder of 186.
The number 5 becomes the next digit in our result. 
Result so far: 71465.0
Subtracting 1715 from 1901 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 9:
343 can be fit into 1860 5 times, resulting in a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 71465.5
If we subtract 1715 from 1860, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 10:
343 can be fit into 1450 4 times, resulting in a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 71465.54
Deduct 1372 from 1450 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
343 goes into 780 2 times with a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 71465.542
The remainder is 94 after subtracting 686 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
The number 343 fits into 940 2 times, leaving a remainder of 254.
Put 2 as the next digit of the answer. 
Result so far: 71465.5422
Subtracting 686 from 940 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

After the division, we end up with 71465.5422 and a remainder of 0.00254.
