We're dividing 630680 by 38 
The aim is to understand the frequency of 38 in 630680.

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
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 38

Step 2:
38 can be fit into 63 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 38 from 63, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 38

Step 3:
If we divide 250 by 38, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 228 away from 250, we end up with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 38

On to step 4:
When dividing 226 by 38, we get 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Deduct 190 from 226 and we're left with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 38

Moving on to step 5:
368 divided by 38 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 1659.0
Deduct 342 from 368 and we're left with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 38

Let's proceed to step 6:
The number 38 fits into 260 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 16596.0
Deduct 228 from 260 and we're left 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.

Advancing to step 7:
38 can be fit into 320 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 16596.8
Deduct 304 from 320 and we're left with 16.
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 8:
38 goes into 160 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 16596.84
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
38 goes into 80 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 16596.842
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 38 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 16596.8421
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
20 divided by 38 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16596.8421
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
38 goes into 200 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 16596.842105
Deduct 190 from 200 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
38 goes into 100 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 16596.8421052
If we subtract 76 from 100, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
38 goes into 240 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 16596.84210526
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 16596.84210526, and the remainder is 1.2e-08.
