We look at the division of 10680643 by 319 
The aim is to understand the frequency of 319 in 10680643.

On to step 1:
The number 319 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 319

Advancing to step 2:
319 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 319

Moving on to step 3:
The number 319 fits into 106 0 times, leaving a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 106 and we're left with 106.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 319

Let's proceed to step 4:
When dividing 1068 by 319, we get 3 with a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 957 from 1068, we get 111.
Include the next digit (0) from the dividend after 111, then repeat: 1110 / 319

Advancing to step 5:
1110 divided by 319 is 3 with a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 957 from 1110, we get 153.
Grab the next digit (6) from the dividend, add it to 153, then carry on: 1536 / 319

Moving on to step 6:
319 can be fit into 1536 4 times, resulting in a remainder of 260.
Write down 4 as next digit of the result. 
Result so far: 334.0
If we take 1276 away from 1536, we end up with 260.
Take the next digit (4) from the dividend and append it to 260, then repeat: 2604 / 319

Advancing to step 7:
The number 319 fits into 2604 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 3348.0
If we subtract 2552 from 2604, we get 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 319

Step 8:
The number 319 fits into 523 1 times, leaving a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 33481.0
Subtract 319 from 523 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
319 can be fit into 2040 6 times, resulting in a remainder of 126.
The next digit of our result is 6. 
Result so far: 33481.6
If we subtract 1914 from 2040, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
If we divide 1260 by 319, we get 3 and a remainder of 303.
The next digit of our result is 3. 
Result so far: 33481.63
If we subtract 957 from 1260, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 11:
319 goes into 3030 9 times with a remainder of 159.
The next digit of our result is 9. 
Result so far: 33481.639
Deduct 2871 from 3030 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 12:
When dividing 1590 by 319, we get 4 with a remainder of 314.
Record the quotient 4 as the next digit in the result. 
Result so far: 33481.6394
Subtracting 1276 from 1590 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 13:
3140 divided by 319 is 9 with a remainder of 269.
Record the quotient 9 as the next digit in the result. 
Result so far: 33481.63949
Deduct 2871 from 3140 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.

On to step 14:
319 goes into 2690 8 times with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 33481.639498
The remainder is 138 after subtracting 2552 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 15:
The number 319 fits into 1380 4 times, leaving a remainder of 104.
The next digit of our result is 4. 
Result so far: 33481.6394984
Subtract 1276 from 1380 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 16:
When dividing 1040 by 319, we get 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 33481.63949843
If we take 957 away from 1040, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

After the division, we end up with 33481.63949843 and a remainder of 8.3e-08.
