48650662 ÷ 123 
The aim is to understand the frequency of 123 in 48650662.

Moving on to step 1:
The number 123 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 123

Step 2:
When dividing 48 by 123, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 123

On to step 3:
When dividing 486 by 123, we get 3 with a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 117 after subtracting 369 from 486.
Grab the next digit (5) from the dividend, add it to 117, then carry on: 1175 / 123

Let's proceed to step 4:
The number 123 fits into 1175 9 times, leaving a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 1107 from 1175 and we're left with 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 123

Advancing to step 5:
The number 123 fits into 680 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 395.0
Deduct 615 from 680 and we're left with 65.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 123

Advancing to step 6:
If we divide 656 by 123, we get 5 and a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 3955.0
Subtracting 615 from 656 leaves us with 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 123

Going ahead to step 7:
The number 123 fits into 416 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 39553.0
Subtract 369 from 416 to get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 123

Going ahead to step 8:
472 divided by 123 is 3 with a remainder of 103.
Write down 3 as next digit of the result. 
Result so far: 395533.0
The remainder is 103 after subtracting 369 from 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 9:
123 can be fit into 1030 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 395533.8
The remainder is 46 after subtracting 984 from 1030.
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 10:
When dividing 460 by 123, we get 3 with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 395533.83
The remainder is 91 after subtracting 369 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 11:
The number 123 fits into 910 7 times, leaving a remainder of 49.
The next digit of our result is 7. 
Result so far: 395533.837
Subtract 861 from 910 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
When dividing 490 by 123, we get 3 with a remainder of 121.
The next digit of our result is 3. 
Result so far: 395533.8373
The remainder is 121 after subtracting 369 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 13:
123 goes into 1210 9 times with a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 395533.83739
Subtracting 1107 from 1210 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 14:
1030 divided by 123 is 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 395533.837398
Subtract 984 from 1030 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
123 goes into 460 3 times with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 395533.8373983
Deduct 369 from 460 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 16:
123 goes into 910 7 times with a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 395533.83739837
If we subtract 861 from 910, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The quotient of the division is 395533.83739837, and the remainder is 4.9e-08.
