993930 divided by 38 
The aim is to understand the frequency of 38 in 993930.

On to step 1:
When dividing 9 by 38, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 38

Moving on to step 2:
When dividing 99 by 38, we get 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 76 from 99, we get 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 38

On to step 3:
233 divided by 38 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 228 from 233 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 38

Step 4:
59 divided by 38 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
The remainder is 21 after subtracting 38 from 59.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 38

Moving on to step 5:
213 divided by 38 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 2615.0
Deduct 190 from 213 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 38

Step 6:
The number 38 fits into 230 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 26156.0
The remainder is 2 after subtracting 228 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 38 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 26156.0
If we take 0 away from 20, we end up with 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 8:
If we divide 200 by 38, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 26156.05
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 9:
The number 38 fits into 100 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 26156.052
Subtracting 76 from 100 leaves us 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.

On to step 10:
If we divide 240 by 38, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 26156.0526
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
120 divided by 38 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 26156.05263
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 38, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 26156.052631
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
The number 38 fits into 220 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 26156.0526315
The remainder is 30 after subtracting 190 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
38 goes into 300 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 26156.05263157
Deduct 266 from 300 and we're left 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.

After the division, we end up with 26156.05263157 and a remainder of 3.4e-08.
