We look at the division of 47784915 by 123 
The aim is to understand the frequency of 123 in 47784915.

Moving on to step 1:
123 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 123

Moving on to step 2:
The number 123 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 123

Moving on to step 3:
If we divide 477 by 123, we get 3 and a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 369 from 477 and we're left with 108.
Bring next digit (8) of the dividend behind the 108 and repeat the process: 1088 / 123

On to step 4:
If we divide 1088 by 123, we get 8 and a remainder of 104.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 104 after subtracting 984 from 1088.
Bring next digit (4) of the dividend behind the 104 and repeat the process: 1044 / 123

Going ahead to step 5:
If we divide 1044 by 123, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 388.0
If we subtract 984 from 1044, we get 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 123

On to step 6:
If we divide 609 by 123, we get 4 and a remainder of 117.
The next digit of our result is 4. 
Result so far: 3884.0
Subtracting 492 from 609 leaves us with 117.
Grab the next digit (1) from the dividend, add it to 117, then carry on: 1171 / 123

On to step 7:
When dividing 1171 by 123, we get 9 with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 38849.0
The remainder is 64 after subtracting 1107 from 1171.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 123

Going ahead to step 8:
If we divide 645 by 123, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 388495.0
Deduct 615 from 645 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 123, we get 2 with a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 388495.2
Subtracting 246 from 300 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
The number 123 fits into 540 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 388495.24
If we subtract 492 from 540, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 123, we get 3 and a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 388495.243
If we subtract 369 from 480, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 12:
The number 123 fits into 1110 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 388495.2439
If we subtract 1107 from 1110, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
If we divide 30 by 123, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 388495.2439
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
The number 123 fits into 300 2 times, leaving a remainder of 54.
The next digit of our result is 2. 
Result so far: 388495.243902
If we take 246 away from 300, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 15:
If we divide 540 by 123, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 388495.2439024
Subtracting 492 from 540 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 16:
480 divided by 123 is 3 with a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 388495.24390243
Subtract 369 from 480 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The final result is 388495.24390243 with a remainder of 1.11e-07.
