We're dividing 45129411 by 507 
The aim is to understand the frequency of 507 in 45129411.

Let's proceed to step 1:
When dividing 4 by 507, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 507

Let's proceed to step 2:
45 divided by 507 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 507

Step 3:
If we divide 451 by 507, we get 0 and a remainder of 451.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 451 to get 451.
Bring next digit (2) of the dividend behind the 451 and repeat the process: 4512 / 507

On to step 4:
If we divide 4512 by 507, we get 8 and a remainder of 456.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 4056 from 4512 leaves us with 456.
Take the next digit (9) from the dividend and append it to 456, then repeat: 4569 / 507

On to step 5:
507 can be fit into 4569 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 4563 from 4569 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 507

On to step 6:
If we divide 64 by 507, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 890.0
If we subtract 0 from 64, we get 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 507

Step 7:
641 divided by 507 is 1 with a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 8901.0
If we subtract 507 from 641, we get 134.
Include the next digit (1) from the dividend after 134, then repeat: 1341 / 507

On to step 8:
1341 divided by 507 is 2 with a remainder of 327.
The number 2 becomes the next digit in our result. 
Result so far: 89012.0
Subtract 1014 from 1341 to get 327.
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:
507 can be fit into 3270 6 times, resulting in a remainder of 228.
The next digit of our result is 6. 
Result so far: 89012.6
If we take 3042 away from 3270, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
2280 divided by 507 is 4 with a remainder of 252.
Use 4 as the next digit of our solution. 
Result so far: 89012.64
Subtracting 2028 from 2280 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
507 goes into 2520 4 times with a remainder of 492.
Record the quotient 4 as the next digit in the result. 
Result so far: 89012.644
If we subtract 2028 from 2520, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

In conclusion, the division gives 89012.644 with a balance of 0.0492.
