Let's divide 1578349 by 128
The aim is to understand the frequency of 128 in 1578349.

Moving on to step 1:
128 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 128

On to step 2:
If we divide 15 by 128, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 128

Advancing to step 3:
128 goes into 157 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 128 from 157 and we're left with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 128

Moving on to step 4:
When dividing 298 by 128, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 256 from 298 leaves us with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 128

Let's proceed to step 5:
128 goes into 423 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 384 from 423 leaves us with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 128

Advancing to step 6:
128 can be fit into 394 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 1233.0
Subtracting 384 from 394 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 128

Moving on to step 7:
When dividing 109 by 128, we get 0 with a remainder of 109.
The next digit of our result is 0. 
Result so far: 12330.0
Deduct 0 from 109 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 8:
1090 divided by 128 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 12330.8
If we subtract 1024 from 1090, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
660 divided by 128 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 12330.85
Subtracting 640 from 660 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 10:
The number 128 fits into 200 1 times, leaving a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 12330.851
If we subtract 128 from 200, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
128 can be fit into 720 5 times, resulting in a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 12330.8515
Deduct 640 from 720 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
The number 128 fits into 800 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 12330.85156
Deduct 768 from 800 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.

On to step 13:
If we divide 320 by 128, we get 2 and a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 12330.851562
If we take 256 away from 320, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
128 can be fit into 640 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12330.8515625
Subtracting 640 from 640 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
If we divide 0 by 128, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12330.8515625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12330.8515625 and a remainder of 0.0.
