We look at the division of 10302243 by 124 
The aim is to understand the frequency of 124 in 10302243.

Going ahead to step 1:
124 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 124

Moving on to step 2:
The number 124 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 124

Going ahead to step 3:
The number 124 fits into 103 0 times, leaving a remainder of 103.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 103, we get 103.
Append the next digit (0) from the dividend to 103 and continue with: 1030 / 124

Step 4:
When dividing 1030 by 124, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 992 from 1030, we get 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 124

Going ahead to step 5:
124 goes into 382 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 372 from 382 leaves us with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 124

Going ahead to step 6:
The number 124 fits into 102 0 times, leaving a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 830.0
Deduct 0 from 102 and we're left with 102.
Bring next digit (4) of the dividend behind the 102 and repeat the process: 1024 / 124

Moving on to step 7:
1024 divided by 124 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8308.0
Deduct 992 from 1024 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 124

Moving on to step 8:
The number 124 fits into 323 2 times, leaving a remainder of 75.
Record the quotient 2 as the next digit in the result. 
Result so far: 83082.0
Subtracting 248 from 323 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
When dividing 750 by 124, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 83082.6
The remainder is 6 after subtracting 744 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 124 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 83082.6
If we take 0 away from 60, 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.

Advancing to step 11:
The number 124 fits into 600 4 times, leaving a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 83082.604
The remainder is 104 after subtracting 496 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 12:
When dividing 1040 by 124, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 83082.6048
The remainder is 48 after subtracting 992 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
The number 124 fits into 480 3 times, leaving a remainder of 108.
The number 3 becomes the next digit in our result. 
Result so far: 83082.60483
The remainder is 108 after subtracting 372 from 480.
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.
Put 8 as the next digit of the answer. 
Result so far: 83082.604838
Subtract 992 from 1080 to 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.

Moving on to step 15:
When dividing 880 by 124, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 83082.6048387
Deduct 868 from 880 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
If we divide 120 by 124, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 83082.6048387
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 83082.6048387 and a remainder of 1.2e-07.
