We're dividing 75147145 by 746 
The aim is to understand the frequency of 746 in 75147145.

Let's proceed to step 1:
If we divide 7 by 746, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 746

Let's proceed to step 2:
75 divided by 746 is 0 with 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.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 746

Step 3:
746 can be fit into 751 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 746 from 751.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 746

Going ahead to step 4:
When dividing 54 by 746, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 54, we get 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 746

Let's proceed to step 5:
746 can be fit into 547 0 times, resulting in a remainder of 547.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 547 after subtracting 0 from 547.
Grab the next digit (1) from the dividend, add it to 547, then carry on: 5471 / 746

Let's proceed to step 6:
5471 divided by 746 is 7 with a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 1007.0
Subtract 5222 from 5471 to get 249.
Grab the next digit (4) from the dividend, add it to 249, then carry on: 2494 / 746

Advancing to step 7:
746 can be fit into 2494 3 times, resulting in a remainder of 256.
The next digit of our result is 3. 
Result so far: 10073.0
If we subtract 2238 from 2494, we get 256.
Take the next digit (5) from the dividend and append it to 256, then repeat: 2565 / 746

Moving on to step 8:
746 can be fit into 2565 3 times, resulting in a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 100733.0
The remainder is 327 after subtracting 2238 from 2565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Let's proceed to step 9:
When dividing 3270 by 746, we get 4 with a remainder of 286.
Record the quotient 4 as the next digit in the result. 
Result so far: 100733.4
The remainder is 286 after subtracting 2984 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
When dividing 2860 by 746, we get 3 with a remainder of 622.
Record the quotient 3 as the next digit in the result. 
Result so far: 100733.43
The remainder is 622 after subtracting 2238 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 11:
746 can be fit into 6220 8 times, resulting in a remainder of 252.
The number 8 becomes the next digit in our result. 
Result so far: 100733.438
If we subtract 5968 from 6220, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 12:
2520 divided by 746 is 3 with a remainder of 282.
Write down 3 as next digit of the result. 
Result so far: 100733.4383
If we take 2238 away from 2520, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 13:
746 can be fit into 2820 3 times, resulting in a remainder of 582.
The next digit of our result is 3. 
Result so far: 100733.43833
Subtracting 2238 from 2820 leaves us with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

The final outcome is 100733.43833, with a leftover of 0.000582.
