We're dividing 77631120 by 38 
The aim is to understand the frequency of 38 in 77631120.

Step 1:
If we divide 7 by 38, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 38

Going ahead to step 2:
38 can be fit into 77 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 76 from 77 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 38

Advancing to step 3:
38 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 16, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 38

Let's proceed to step 4:
38 goes into 163 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
The remainder is 11 after subtracting 152 from 163.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 38

Going ahead to step 5:
38 goes into 111 2 times with a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 2042.0
If we subtract 76 from 111, we get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 38

Advancing to step 6:
351 divided by 38 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 20429.0
Deduct 342 from 351 and we're left with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 38

On to step 7:
The number 38 fits into 92 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 204292.0
The remainder is 16 after subtracting 76 from 92.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 38

On to step 8:
38 goes into 160 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2042924.0
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 38 fits into 80 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2042924.2
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 38 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 2042924.21
If we subtract 38 from 40, we get 2.
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:
When dividing 20 by 38, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2042924.21
Subtract 0 from 20 to 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:
When dividing 200 by 38, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2042924.2105
Subtract 190 from 200 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
100 divided by 38 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2042924.21052
Deduct 76 from 100 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
If we divide 240 by 38, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 2042924.210526
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 15:
38 goes into 120 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2042924.2105263
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 16:
The number 38 fits into 60 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 2042924.21052631
If we subtract 38 from 60, we 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.

Our division results in 2042924.21052631 with a remaining 2.2e-08.
