We look at the division of 55940464 by 343 
The aim is to understand the frequency of 343 in 55940464.

Let's proceed to step 1:
5 divided by 343 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 343

Let's proceed to step 2:
55 divided by 343 is 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 343

On to step 3:
When dividing 559 by 343, we get 1 with a remainder of 216.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 343 away from 559, we end up with 216.
Append the next digit (4) from the dividend to 216 and continue with: 2164 / 343

Moving on to step 4:
When dividing 2164 by 343, we get 6 with a remainder of 106.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 2058 from 2164 leaves us with 106.
Fetch the next digit (0) from the dividend, attach it to 106 and continue: 1060 / 343

Let's proceed to step 5:
When dividing 1060 by 343, we get 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 163.0
Subtract 1029 from 1060 to get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 343

Step 6:
343 goes into 314 0 times with a remainder of 314.
Write down 0 as next digit of the result. 
Result so far: 1630.0
Subtract 0 from 314 to get 314.
Bring next digit (6) of the dividend behind the 314 and repeat the process: 3146 / 343

Step 7:
If we divide 3146 by 343, we get 9 and a remainder of 59.
The next digit of our result is 9. 
Result so far: 16309.0
Subtract 3087 from 3146 to get 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 343

Moving on to step 8:
594 divided by 343 is 1 with a remainder of 251.
The next digit of our result is 1. 
Result so far: 163091.0
If we take 343 away from 594, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 9:
2510 divided by 343 is 7 with a remainder of 109.
Use 7 as the next digit of our solution. 
Result so far: 163091.7
If we subtract 2401 from 2510, we 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.

Moving on to step 10:
When dividing 1090 by 343, we get 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 163091.73
Deduct 1029 from 1090 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
343 goes into 610 1 times with a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 163091.731
If we take 343 away from 610, we end up with 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 12:
The number 343 fits into 2670 7 times, leaving a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 163091.7317
Deduct 2401 from 2670 and we're left 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 13:
343 can be fit into 2690 7 times, resulting in a remainder of 289.
The next digit of our result is 7. 
Result so far: 163091.73177
If we subtract 2401 from 2690, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The final result is 163091.73177 with a remainder of 0.000289.
