Let's divide 19689379 by 343
The aim is to understand the frequency of 343 in 19689379.

Let's proceed to step 1:
343 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 343

Step 2:
19 divided by 343 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 343

On to step 3:
343 can be fit into 196 0 times, resulting in a remainder of 196.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 196 and we're left with 196.
Bring next digit (8) of the dividend behind the 196 and repeat the process: 1968 / 343

On to step 4:
343 goes into 1968 5 times with a remainder of 253.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 253 after subtracting 1715 from 1968.
Append the next digit (9) from the dividend to 253 and continue with: 2539 / 343

Moving on to step 5:
The number 343 fits into 2539 7 times, leaving a remainder of 138.
The next digit of our result is 7. 
Result so far: 57.0
Subtract 2401 from 2539 to get 138.
Take the next digit (3) from the dividend and append it to 138, then repeat: 1383 / 343

Moving on to step 6:
343 goes into 1383 4 times with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 574.0
If we subtract 1372 from 1383, we get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 343

Let's proceed to step 7:
When dividing 117 by 343, we get 0 with a remainder of 117.
The next digit of our result is 0. 
Result so far: 5740.0
Subtract 0 from 117 to get 117.
Include the next digit (9) from the dividend after 117, then repeat: 1179 / 343

On to step 8:
When dividing 1179 by 343, we get 3 with a remainder of 150.
Record the quotient 3 as the next digit in the result. 
Result so far: 57403.0
Subtracting 1029 from 1179 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
343 goes into 1500 4 times with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 57403.4
Deduct 1372 from 1500 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 10:
343 goes into 1280 3 times with a remainder of 251.
Put 3 as the next digit of the answer. 
Result so far: 57403.43
Subtract 1029 from 1280 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Moving on to step 11:
343 goes into 2510 7 times with a remainder of 109.
The next digit of our result is 7. 
Result so far: 57403.437
Subtract 2401 from 2510 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 12:
The number 343 fits into 1090 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 57403.4373
Subtract 1029 from 1090 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 13:
The number 343 fits into 610 1 times, leaving a remainder of 267.
Record the quotient 1 as the next digit in the result. 
Result so far: 57403.43731
If we subtract 343 from 610, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 14:
2670 divided by 343 is 7 with a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 57403.437317
Subtracting 2401 from 2670 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 15:
2690 divided by 343 is 7 with a remainder of 289.
Write down 7 as next digit of the result. 
Result so far: 57403.4373177
Deduct 2401 from 2690 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

After the division, we end up with 57403.4373177 and a remainder of 2.89e-06.
