69724572 ÷ 124 
The aim is to understand the frequency of 124 in 69724572.

Going ahead to step 1:
If we divide 6 by 124, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 124

On to step 2:
The number 124 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 124

On to step 3:
The number 124 fits into 697 5 times, leaving a remainder of 77.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 620 from 697 leaves us with 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 124

Going ahead to step 4:
If we divide 772 by 124, we get 6 and a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 744 from 772 to get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 124

Let's proceed to step 5:
124 can be fit into 284 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 562.0
The remainder is 36 after subtracting 248 from 284.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 124

Advancing to step 6:
124 goes into 365 2 times with a remainder of 117.
Put 2 as the next digit of the answer. 
Result so far: 5622.0
Subtract 248 from 365 to get 117.
Append the next digit (7) from the dividend to 117 and continue with: 1177 / 124

On to step 7:
The number 124 fits into 1177 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 56229.0
If we take 1116 away from 1177, we end up with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 124

Step 8:
124 goes into 612 4 times with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 562294.0
If we take 496 away from 612, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
1160 divided by 124 is 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 562294.9
If we take 1116 away from 1160, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
124 can be fit into 440 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 562294.93
If we subtract 372 from 440, 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 11:
The number 124 fits into 680 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 562294.935
Subtract 620 from 680 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
124 goes into 600 4 times with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 562294.9354
Deduct 496 from 600 and we're left 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.

Let's proceed to step 13:
If we divide 1040 by 124, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 562294.93548
If we subtract 992 from 1040, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
480 divided by 124 is 3 with a remainder of 108.
The next digit of our result is 3. 
Result so far: 562294.935483
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.

Step 15:
1080 divided by 124 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 562294.9354838
Subtracting 992 from 1080 leaves us with 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 16:
The number 124 fits into 880 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 562294.93548387
If we take 868 away from 880, we end up 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.

After the division, we end up with 562294.93548387 and a remainder of 1.2e-08.
