We look at the division of 671919 by 38 
The aim is to understand the frequency of 38 in 671919.

Moving on to step 1:
If we divide 6 by 38, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 38

Going ahead to step 2:
When dividing 67 by 38, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 38 from 67, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 38

On to step 3:
When dividing 291 by 38, we get 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 266 from 291 and we're left with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 38

Advancing to step 4:
The number 38 fits into 259 6 times, leaving a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
If we take 228 away from 259, we end up with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 38

Moving on to step 5:
38 can be fit into 311 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 1768.0
Subtract 304 from 311 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 38

Advancing to step 6:
79 divided by 38 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 17682.0
Subtracting 76 from 79 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
38 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 17682.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
38 can be fit into 300 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 17682.07
Subtracting 266 from 300 leaves us 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.

On to step 9:
The number 38 fits into 340 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 17682.078
The remainder is 36 after subtracting 304 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
When dividing 360 by 38, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 17682.0789
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
38 can be fit into 180 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 17682.07894
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
280 divided by 38 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 17682.078947
Deduct 266 from 280 and we're left 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 13:
38 can be fit into 140 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 17682.0789473
If we take 114 away from 140, we end up 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.

Let's proceed to step 14:
260 divided by 38 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 17682.07894736
Subtracting 228 from 260 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 17682.07894736 with a remainder of 3.2e-08.
