We look at the division of 64450767 by 124 
The aim is to understand the frequency of 124 in 64450767.

Advancing to step 1:
If we divide 6 by 124, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 124

Going ahead to step 2:
124 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 124

Advancing to step 3:
124 goes into 644 5 times with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 620 from 644 leaves us with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 124

Advancing to step 4:
124 can be fit into 245 1 times, resulting in a remainder of 121.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we take 124 away from 245, we end up with 121.
Append the next digit (0) from the dividend to 121 and continue with: 1210 / 124

Let's proceed to step 5:
124 goes into 1210 9 times with a remainder of 94.
Write down 9 as next digit of the result. 
Result so far: 519.0
The remainder is 94 after subtracting 1116 from 1210.
Bring next digit (7) of the dividend behind the 94 and repeat the process: 947 / 124

Moving on to step 6:
The number 124 fits into 947 7 times, leaving a remainder of 79.
The next digit of our result is 7. 
Result so far: 5197.0
If we take 868 away from 947, we end up with 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 124

Advancing to step 7:
When dividing 796 by 124, we get 6 with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 51976.0
If we subtract 744 from 796, we get 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 124

Advancing to step 8:
124 goes into 527 4 times with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 519764.0
If we take 496 away from 527, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
If we divide 310 by 124, we get 2 and a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 519764.2
Subtract 248 from 310 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
620 divided by 124 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 519764.25
Subtract 620 from 620 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
0 divided by 124 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 519764.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 124 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 519764.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 519764.25 with a remainder of 0.0.
