Let's divide 644609 by 38
The aim is to understand the frequency of 38 in 644609.

On to step 1:
38 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 38

Let's proceed to step 2:
If we divide 64 by 38, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 38 from 64, we get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 38

Let's proceed to step 3:
The number 38 fits into 264 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 228 from 264 to get 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 38

Moving on to step 4:
If we divide 366 by 38, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 169.0
Deduct 342 from 366 and we're left with 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 38

Let's proceed to step 5:
The number 38 fits into 240 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 1696.0
Subtract 228 from 240 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 38

Step 6:
When dividing 129 by 38, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 16963.0
If we subtract 114 from 129, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 38 fits into 150 3 times, leaving a remainder of 36.
The next digit of our result is 3. 
Result so far: 16963.3
If we subtract 114 from 150, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
38 can be fit into 360 9 times, resulting in a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 16963.39
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.

Let's proceed to step 9:
38 goes into 180 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 16963.394
Deduct 152 from 180 and we're left 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.

Advancing to step 10:
280 divided by 38 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 16963.3947
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
The number 38 fits into 140 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 16963.39473
Subtract 114 from 140 to 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.

On to step 12:
When dividing 260 by 38, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 16963.394736
If we take 228 away from 260, we end up 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.

On to step 13:
320 divided by 38 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 16963.3947368
The remainder is 16 after subtracting 304 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 38, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 16963.39473684
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 16963.39473684 with a balance of 8e-09.
