We look at the division of 28091758 by 347 
The aim is to understand the frequency of 347 in 28091758.

On to step 1:
When dividing 2 by 347, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 347

Step 2:
28 divided by 347 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 347

Moving on to step 3:
If we divide 280 by 347, we get 0 and a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 280 and we're left with 280.
Fetch the next digit (9) from the dividend, attach it to 280 and continue: 2809 / 347

Going ahead to step 4:
When dividing 2809 by 347, we get 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 33 after subtracting 2776 from 2809.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 347

Step 5:
If we divide 331 by 347, we get 0 and a remainder of 331.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we subtract 0 from 331, we get 331.
Append the next digit (7) from the dividend to 331 and continue with: 3317 / 347

Advancing to step 6:
347 can be fit into 3317 9 times, resulting in a remainder of 194.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
Subtract 3123 from 3317 to get 194.
Fetch the next digit (5) from the dividend, attach it to 194 and continue: 1945 / 347

On to step 7:
If we divide 1945 by 347, we get 5 and a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 8095.0
Subtracting 1735 from 1945 leaves us with 210.
Take the next digit (8) from the dividend and append it to 210, then repeat: 2108 / 347

On to step 8:
347 goes into 2108 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 80956.0
Subtracting 2082 from 2108 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
347 goes into 260 0 times with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 80956.0
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
When dividing 2600 by 347, we get 7 with a remainder of 171.
Use 7 as the next digit of our solution. 
Result so far: 80956.07
Deduct 2429 from 2600 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 11:
1710 divided by 347 is 4 with a remainder of 322.
The number 4 becomes the next digit in our result. 
Result so far: 80956.074
If we take 1388 away from 1710, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 12:
3220 divided by 347 is 9 with a remainder of 97.
The next digit of our result is 9. 
Result so far: 80956.0749
Subtract 3123 from 3220 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 13:
When dividing 970 by 347, we get 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 80956.07492
If we subtract 694 from 970, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 14:
347 goes into 2760 7 times with a remainder of 331.
Write down 7 as next digit of the result. 
Result so far: 80956.074927
If we take 2429 away from 2760, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

On to step 15:
If we divide 3310 by 347, we get 9 and a remainder of 187.
The next digit of our result is 9. 
Result so far: 80956.0749279
Subtracting 3123 from 3310 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 16:
347 can be fit into 1870 5 times, resulting in a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 80956.07492795
Subtract 1735 from 1870 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

After the division, we end up with 80956.07492795 and a remainder of 1.35e-07.
