We look at the division of 50173472 by 349 
The aim is to understand the frequency of 349 in 50173472.

Moving on to step 1:
The number 349 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 349

Going ahead to step 2:
If we divide 50 by 349, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 349

Moving on to step 3:
349 can be fit into 501 1 times, resulting in a remainder of 152.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 152 after subtracting 349 from 501.
Take the next digit (7) from the dividend and append it to 152, then repeat: 1527 / 349

On to step 4:
The number 349 fits into 1527 4 times, leaving a remainder of 131.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 1396 from 1527 to get 131.
Append the next digit (3) from the dividend to 131 and continue with: 1313 / 349

Let's proceed to step 5:
If we divide 1313 by 349, we get 3 and a remainder of 266.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtract 1047 from 1313 to get 266.
Append the next digit (4) from the dividend to 266 and continue with: 2664 / 349

Let's proceed to step 6:
If we divide 2664 by 349, we get 7 and a remainder of 221.
Use 7 as the next digit of our solution. 
Result so far: 1437.0
Deduct 2443 from 2664 and we're left with 221.
Append the next digit (7) from the dividend to 221 and continue with: 2217 / 349

Moving on to step 7:
2217 divided by 349 is 6 with a remainder of 123.
Write down 6 as next digit of the result. 
Result so far: 14376.0
If we take 2094 away from 2217, we end up with 123.
Take the next digit (2) from the dividend and append it to 123, then repeat: 1232 / 349

Let's proceed to step 8:
1232 divided by 349 is 3 with a remainder of 185.
The next digit of our result is 3. 
Result so far: 143763.0
Deduct 1047 from 1232 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
If we divide 1850 by 349, we get 5 and a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 143763.5
The remainder is 105 after subtracting 1745 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
349 can be fit into 1050 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 143763.53
The remainder is 3 after subtracting 1047 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
349 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 143763.53
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 349 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 143763.53
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 143763.53, with a leftover of 0.003.
