991579 ÷ 38 
The aim is to understand the frequency of 38 in 991579.

Advancing to step 1:
38 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 38

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
Subtract 76 from 99 to get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 38

On to step 3:
38 goes into 231 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtracting 228 from 231 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 38

Step 4:
The number 38 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 260.0
If we take 0 away from 35, we end up with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 38

Advancing to step 5:
357 divided by 38 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 2609.0
Deduct 342 from 357 and we're left with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 38

Moving on to step 6:
38 goes into 159 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 26094.0
Deduct 152 from 159 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
38 goes into 70 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 26094.1
Subtract 38 from 70 to get 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 8:
320 divided by 38 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 26094.18
Subtracting 304 from 320 leaves us 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.

Step 9:
The number 38 fits into 160 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 26094.184
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.

Moving on to step 10:
80 divided by 38 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 26094.1842
Deduct 76 from 80 and we're left with 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 11:
When dividing 40 by 38, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 26094.18421
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.

Going ahead to step 12:
38 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 26094.18421
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 13:
When dividing 200 by 38, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 26094.1842105
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.

Going ahead to step 14:
38 goes into 100 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 26094.18421052
If we take 76 away from 100, we end up 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.

The quotient of the division is 26094.18421052, and the remainder is 2.4e-08.
