74631082 ÷ 123 
The aim is to understand the frequency of 123 in 74631082.

Moving on to step 1:
The number 123 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 123

Advancing to step 2:
When dividing 74 by 123, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Append the next digit (6) from the dividend to 74 and continue with: 746 / 123

On to step 3:
The number 123 fits into 746 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 738 from 746, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 123

On to step 4:
123 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we take 0 away from 83, we end up with 83.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 123

Going ahead to step 5:
When dividing 831 by 123, we get 6 with a remainder of 93.
The number 6 becomes the next digit in our result. 
Result so far: 606.0
If we subtract 738 from 831, we get 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 123

Moving on to step 6:
123 can be fit into 930 7 times, resulting in a remainder of 69.
The next digit of our result is 7. 
Result so far: 6067.0
The remainder is 69 after subtracting 861 from 930.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 123

On to step 7:
The number 123 fits into 698 5 times, leaving a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 60675.0
Deduct 615 from 698 and we're left with 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 123

Moving on to step 8:
When dividing 832 by 123, we get 6 with a remainder of 94.
Use 6 as the next digit of our solution. 
Result so far: 606756.0
Subtract 738 from 832 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 9:
If we divide 940 by 123, we get 7 and a remainder of 79.
Put 7 as the next digit of the answer. 
Result so far: 606756.7
The remainder is 79 after subtracting 861 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
123 goes into 790 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 606756.76
Subtract 738 from 790 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
123 goes into 520 4 times with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 606756.764
Subtracting 492 from 520 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
123 goes into 280 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 606756.7642
Deduct 246 from 280 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
123 goes into 340 2 times with a remainder of 94.
The number 2 becomes the next digit in our result. 
Result so far: 606756.76422
If we take 246 away from 340, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

After the division, we end up with 606756.76422 and a remainder of 9.4e-05.
