12382236 ÷ 123 
The aim is to understand the frequency of 123 in 12382236.

Going ahead to step 1:
When dividing 1 by 123, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 123

Moving on to step 2:
The number 123 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 123

Let's proceed to step 3:
If we divide 123 by 123, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 123 from 123, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 123

Going ahead to step 4:
123 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 123

Step 5:
When dividing 82 by 123, we get 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 82 and we're left with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 123

Advancing to step 6:
123 can be fit into 822 6 times, resulting in a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
If we subtract 738 from 822, we get 84.
Append the next digit (3) from the dividend to 84 and continue with: 843 / 123

Let's proceed to step 7:
123 goes into 843 6 times with a remainder of 105.
Record the quotient 6 as the next digit in the result. 
Result so far: 10066.0
The remainder is 105 after subtracting 738 from 843.
Take the next digit (6) from the dividend and append it to 105, then repeat: 1056 / 123

Step 8:
123 can be fit into 1056 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 100668.0
Deduct 984 from 1056 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
123 can be fit into 720 5 times, resulting in a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 100668.5
If we take 615 away from 720, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 10:
123 can be fit into 1050 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 100668.58
Deduct 984 from 1050 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
The number 123 fits into 660 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 100668.585
If we take 615 away from 660, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
When dividing 450 by 123, we get 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 100668.5853
Subtracting 369 from 450 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 13:
123 goes into 810 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 100668.58536
Subtracting 738 from 810 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
720 divided by 123 is 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 100668.585365
If we take 615 away from 720, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
If we divide 1050 by 123, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 100668.5853658
If we subtract 984 from 1050, 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.

On to step 16:
If we divide 660 by 123, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 100668.58536585
Deduct 615 from 660 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 100668.58536585 with a remaining 4.5e-08.
