15454523 divided by 123 
The aim is to understand the frequency of 123 in 15454523.

Going ahead to step 1:
123 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 123

On to step 2:
123 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 123

Going ahead to step 3:
When dividing 154 by 123, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 123 from 154 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 123

Going ahead to step 4:
315 divided by 123 is 2 with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 246 away from 315, we end up with 69.
Fetch the next digit (4) from the dividend, attach it to 69 and continue: 694 / 123

Let's proceed to step 5:
694 divided by 123 is 5 with a remainder of 79.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 615 from 694 leaves us with 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 123

On to step 6:
If we divide 795 by 123, we get 6 and a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 1256.0
Subtract 738 from 795 to get 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 123

Going ahead to step 7:
When dividing 572 by 123, we get 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 12564.0
If we take 492 away from 572, we end up with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 123

Let's proceed to step 8:
123 can be fit into 803 6 times, resulting in a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 125646.0
If we take 738 away from 803, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
123 can be fit into 650 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 125646.5
The remainder is 35 after subtracting 615 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
If we divide 350 by 123, we get 2 and a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 125646.52
Subtracting 246 from 350 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 11:
If we divide 1040 by 123, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 125646.528
Subtracting 984 from 1040 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
The number 123 fits into 560 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 125646.5284
If we take 492 away from 560, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
The number 123 fits into 680 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 125646.52845
Subtract 615 from 680 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 14:
123 can be fit into 650 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 125646.528455
Subtract 615 from 650 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 125646.528455 with a balance of 3.5e-06.
