We look at the division of 680016 by 38 
The aim is to understand the frequency of 38 in 680016.

Step 1:
If we divide 6 by 38, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 38

Step 2:
When dividing 68 by 38, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 30 after subtracting 38 from 68.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 38

On to step 3:
38 goes into 300 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 266 away from 300, we end up with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 38

Step 4:
38 can be fit into 340 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Subtracting 304 from 340 leaves us with 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 38

Step 5:
361 divided by 38 is 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 1789.0
Deduct 342 from 361 and we're left with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 38

Step 6:
38 can be fit into 196 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 17895.0
If we subtract 190 from 196, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 38 fits into 60 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 17895.1
Subtract 38 from 60 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
38 goes into 220 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 17895.15
The remainder is 30 after subtracting 190 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
300 divided by 38 is 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 17895.157
Deduct 266 from 300 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
38 can be fit into 340 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 17895.1578
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
38 goes into 360 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 17895.15789
If we subtract 342 from 360, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
If we divide 180 by 38, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 17895.157894
Subtracting 152 from 180 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
If we divide 280 by 38, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 17895.1578947
Subtracting 266 from 280 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
When dividing 140 by 38, we get 3 with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 17895.15789473
If we subtract 114 from 140, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 17895.15789473 and a remainder of 2.6e-08.
