We're dividing 75604204 by 124 
The aim is to understand the frequency of 124 in 75604204.

Advancing to step 1:
When dividing 7 by 124, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 124

Let's proceed to step 2:
124 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (6) from the dividend to 75 and continue with: 756 / 124

On to step 3:
756 divided by 124 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 12 after subtracting 744 from 756.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 124

On to step 4:
If we divide 120 by 124, we get 0 and a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we take 0 away from 120, we end up with 120.
Append the next digit (4) from the dividend to 120 and continue with: 1204 / 124

On to step 5:
The number 124 fits into 1204 9 times, leaving a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 609.0
If we subtract 1116 from 1204, we get 88.
Include the next digit (2) from the dividend after 88, then repeat: 882 / 124

Moving on to step 6:
When dividing 882 by 124, we get 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 6097.0
Subtracting 868 from 882 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 124

Step 7:
The number 124 fits into 140 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 60971.0
If we take 124 away from 140, we end up with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 124

Advancing to step 8:
164 divided by 124 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 609711.0
Deduct 124 from 164 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 124, we get 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 609711.3
If we take 372 away from 400, we end up 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 10:
280 divided by 124 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 609711.32
Subtract 248 from 280 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
124 goes into 320 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 609711.322
Subtracting 248 from 320 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 609711.322 with a balance of 0.0072.
