Let's divide 75146505 by 459
The aim is to understand the frequency of 459 in 75146505.

Going ahead to step 1:
When dividing 7 by 459, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 459

Let's proceed to step 2:
The number 459 fits into 75 0 times, leaving a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 459

On to step 3:
751 divided by 459 is 1 with a remainder of 292.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 459 from 751, we get 292.
Grab the next digit (4) from the dividend, add it to 292, then carry on: 2924 / 459

Step 4:
2924 divided by 459 is 6 with a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 2754 from 2924 to get 170.
Include the next digit (6) from the dividend after 170, then repeat: 1706 / 459

On to step 5:
When dividing 1706 by 459, we get 3 with a remainder of 329.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we subtract 1377 from 1706, we get 329.
Include the next digit (5) from the dividend after 329, then repeat: 3295 / 459

Moving on to step 6:
3295 divided by 459 is 7 with a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 1637.0
If we subtract 3213 from 3295, we get 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 459

Advancing to step 7:
If we divide 820 by 459, we get 1 and a remainder of 361.
Put 1 as the next digit of the answer. 
Result so far: 16371.0
If we subtract 459 from 820, we get 361.
Grab the next digit (5) from the dividend, add it to 361, then carry on: 3615 / 459

Step 8:
When dividing 3615 by 459, we get 7 with a remainder of 402.
The number 7 becomes the next digit in our result. 
Result so far: 163717.0
If we take 3213 away from 3615, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 9:
If we divide 4020 by 459, we get 8 and a remainder of 348.
Record the quotient 8 as the next digit in the result. 
Result so far: 163717.8
Subtract 3672 from 4020 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 10:
When dividing 3480 by 459, we get 7 with a remainder of 267.
The next digit of our result is 7. 
Result so far: 163717.87
If we take 3213 away from 3480, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 11:
The number 459 fits into 2670 5 times, leaving a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 163717.875
The remainder is 375 after subtracting 2295 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 12:
The number 459 fits into 3750 8 times, leaving a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 163717.8758
Deduct 3672 from 3750 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
The number 459 fits into 780 1 times, leaving a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 163717.87581
If we subtract 459 from 780, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 14:
459 can be fit into 3210 6 times, resulting in a remainder of 456.
The number 6 becomes the next digit in our result. 
Result so far: 163717.875816
If we take 2754 away from 3210, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 15:
The number 459 fits into 4560 9 times, leaving a remainder of 429.
The number 9 becomes the next digit in our result. 
Result so far: 163717.8758169
If we take 4131 away from 4560, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Advancing to step 16:
When dividing 4290 by 459, we get 9 with a remainder of 159.
Use 9 as the next digit of our solution. 
Result so far: 163717.87581699
If we subtract 4131 from 4290, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

After the division, we end up with 163717.87581699 and a remainder of 1.59e-07.
