We look at the division of 65686502 by 124 
The aim is to understand the frequency of 124 in 65686502.

Moving on to step 1:
124 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 124

Let's proceed to step 2:
When dividing 65 by 124, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 124

On to step 3:
656 divided by 124 is 5 with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 620 from 656 leaves us with 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 124

Going ahead to step 4:
124 goes into 368 2 times with a remainder of 120.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 248 from 368 and we're left with 120.
Include the next digit (6) from the dividend after 120, then repeat: 1206 / 124

Step 5:
The number 124 fits into 1206 9 times, leaving a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
If we subtract 1116 from 1206, we get 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 124

On to step 6:
124 can be fit into 905 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 5297.0
If we subtract 868 from 905, we get 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 124

Step 7:
The number 124 fits into 370 2 times, leaving a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 52972.0
Deduct 248 from 370 and we're left with 122.
Bring next digit (2) of the dividend behind the 122 and repeat the process: 1222 / 124

Going ahead to step 8:
The number 124 fits into 1222 9 times, leaving a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 529729.0
Subtracting 1116 from 1222 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
124 goes into 1060 8 times with a remainder of 68.
The next digit of our result is 8. 
Result so far: 529729.8
If we subtract 992 from 1060, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
124 can be fit into 680 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 529729.85
If we take 620 away from 680, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
124 goes into 600 4 times with a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 529729.854
If we take 496 away from 600, we end up 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.

Advancing to step 12:
When dividing 1040 by 124, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 529729.8548
If we take 992 away from 1040, we end up 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.

Advancing to step 13:
124 can be fit into 480 3 times, resulting in a remainder of 108.
Record the quotient 3 as the next digit in the result. 
Result so far: 529729.85483
Subtract 372 from 480 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 14:
124 can be fit into 1080 8 times, resulting in a remainder of 88.
The next digit of our result is 8. 
Result so far: 529729.854838
If we subtract 992 from 1080, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 15:
The number 124 fits into 880 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 529729.8548387
If we subtract 868 from 880, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
124 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 529729.8548387
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 529729.8548387 with a balance of 1.2e-07.
