96335815 ÷ 438 
The aim is to understand the frequency of 438 in 96335815.

Step 1:
If we divide 9 by 438, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 438

On to step 2:
When dividing 96 by 438, we get 0 with a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 96, we get 96.
Include the next digit (3) from the dividend after 96, then repeat: 963 / 438

Advancing to step 3:
If we divide 963 by 438, we get 2 and a remainder of 87.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 876 from 963, we get 87.
Fetch the next digit (3) from the dividend, attach it to 87 and continue: 873 / 438

Moving on to step 4:
When dividing 873 by 438, we get 1 with a remainder of 435.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 435 after subtracting 438 from 873.
Include the next digit (5) from the dividend after 435, then repeat: 4355 / 438

Moving on to step 5:
The number 438 fits into 4355 9 times, leaving a remainder of 413.
The next digit of our result is 9. 
Result so far: 219.0
Subtract 3942 from 4355 to get 413.
Grab the next digit (8) from the dividend, add it to 413, then carry on: 4138 / 438

On to step 6:
The number 438 fits into 4138 9 times, leaving a remainder of 196.
The next digit of our result is 9. 
Result so far: 2199.0
Subtracting 3942 from 4138 leaves us with 196.
Append the next digit (1) from the dividend to 196 and continue with: 1961 / 438

Let's proceed to step 7:
1961 divided by 438 is 4 with a remainder of 209.
The next digit of our result is 4. 
Result so far: 21994.0
The remainder is 209 after subtracting 1752 from 1961.
Bring next digit (5) of the dividend behind the 209 and repeat the process: 2095 / 438

Moving on to step 8:
If we divide 2095 by 438, we get 4 and a remainder of 343.
Record the quotient 4 as the next digit in the result. 
Result so far: 219944.0
Deduct 1752 from 2095 and we're left with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
When dividing 3430 by 438, we get 7 with a remainder of 364.
Put 7 as the next digit of the answer. 
Result so far: 219944.7
Deduct 3066 from 3430 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 10:
The number 438 fits into 3640 8 times, leaving a remainder of 136.
The next digit of our result is 8. 
Result so far: 219944.78
Deduct 3504 from 3640 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 11:
If we divide 1360 by 438, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 219944.783
The remainder is 46 after subtracting 1314 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
460 divided by 438 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 219944.7831
If we subtract 438 from 460, 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.

On to step 13:
When dividing 220 by 438, we get 0 with a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 219944.7831
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
When dividing 2200 by 438, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 219944.783105
If we subtract 2190 from 2200, we 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.

Moving on to step 15:
When dividing 100 by 438, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 219944.783105
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
438 can be fit into 1000 2 times, resulting in a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 219944.78310502
If we take 876 away from 1000, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 219944.78310502 with a remainder of 1.24e-07.
