We look at the division of 17333917 by 319 
The aim is to understand the frequency of 319 in 17333917.

On to step 1:
If we divide 1 by 319, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 319

Step 2:
319 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 319

Advancing to step 3:
173 divided by 319 is 0 with a remainder of 173.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 173 after subtracting 0 from 173.
Bring next digit (3) of the dividend behind the 173 and repeat the process: 1733 / 319

Moving on to step 4:
If we divide 1733 by 319, we get 5 and a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 1595 from 1733 to get 138.
Grab the next digit (3) from the dividend, add it to 138, then carry on: 1383 / 319

Let's proceed to step 5:
The number 319 fits into 1383 4 times, leaving a remainder of 107.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Deduct 1276 from 1383 and we're left with 107.
Bring next digit (9) of the dividend behind the 107 and repeat the process: 1079 / 319

Going ahead to step 6:
319 goes into 1079 3 times with a remainder of 122.
The next digit of our result is 3. 
Result so far: 543.0
If we take 957 away from 1079, we end up with 122.
Grab the next digit (1) from the dividend, add it to 122, then carry on: 1221 / 319

Let's proceed to step 7:
1221 divided by 319 is 3 with a remainder of 264.
Record the quotient 3 as the next digit in the result. 
Result so far: 5433.0
If we subtract 957 from 1221, we get 264.
Bring next digit (7) of the dividend behind the 264 and repeat the process: 2647 / 319

Step 8:
The number 319 fits into 2647 8 times, leaving a remainder of 95.
The number 8 becomes the next digit in our result. 
Result so far: 54338.0
Subtracting 2552 from 2647 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 9:
When dividing 950 by 319, we get 2 with a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 54338.2
Subtract 638 from 950 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 10:
319 goes into 3120 9 times with a remainder of 249.
Put 9 as the next digit of the answer. 
Result so far: 54338.29
If we subtract 2871 from 3120, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 11:
The number 319 fits into 2490 7 times, leaving a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 54338.297
Deduct 2233 from 2490 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 12:
2570 divided by 319 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 54338.2978
The remainder is 18 after subtracting 2552 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
319 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 54338.2978
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 14:
1800 divided by 319 is 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 54338.297805
If we subtract 1595 from 1800, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 15:
The number 319 fits into 2050 6 times, leaving a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 54338.2978056
The remainder is 136 after subtracting 1914 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 16:
When dividing 1360 by 319, we get 4 with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 54338.29780564
If we take 1276 away from 1360, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 54338.29780564 with a remainder of 8.4e-08.
