Let's divide 649925 by 38
The aim is to understand the frequency of 38 in 649925.

Going ahead to step 1:
The number 38 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 38

Step 2:
When dividing 64 by 38, we get 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 38 from 64 to get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 38

On to step 3:
When dividing 269 by 38, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 266 from 269 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 38

Moving on to step 4:
If we divide 39 by 38, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 171.0
If we subtract 38 from 39, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 38

On to step 5:
38 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 1710.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 38

Let's proceed to step 6:
38 can be fit into 125 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 17103.0
Subtract 114 from 125 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
If we divide 110 by 38, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 17103.2
Subtract 76 from 110 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
38 goes into 340 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 17103.28
Subtract 304 from 340 to 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.

On to step 9:
360 divided by 38 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 17103.289
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.

On to step 10:
The number 38 fits into 180 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 17103.2894
If we take 152 away from 180, we end up 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 11:
38 goes into 280 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 17103.28947
If we subtract 266 from 280, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
If we divide 140 by 38, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 17103.289473
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.

Advancing to step 13:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 17103.2894736
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
The number 38 fits into 320 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 17103.28947368
Subtract 304 from 320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 17103.28947368, with a leftover of 1.6e-08.
