Let's divide 75088435 by 405
The aim is to understand the frequency of 405 in 75088435.

Going ahead to step 1:
405 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 405

On to step 2:
The number 405 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.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 405

On to step 3:
750 divided by 405 is 1 with a remainder of 345.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 405 from 750 to get 345.
Fetch the next digit (8) from the dividend, attach it to 345 and continue: 3458 / 405

On to step 4:
When dividing 3458 by 405, we get 8 with a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 218 after subtracting 3240 from 3458.
Include the next digit (8) from the dividend after 218, then repeat: 2188 / 405

Let's proceed to step 5:
405 can be fit into 2188 5 times, resulting in a remainder of 163.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Deduct 2025 from 2188 and we're left with 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 405

Step 6:
405 goes into 1634 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 1854.0
The remainder is 14 after subtracting 1620 from 1634.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 405

Going ahead to step 7:
405 can be fit into 143 0 times, resulting in a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 18540.0
If we subtract 0 from 143, we get 143.
Include the next digit (5) from the dividend after 143, then repeat: 1435 / 405

Advancing to step 8:
405 goes into 1435 3 times with a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 185403.0
Subtracting 1215 from 1435 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 9:
405 goes into 2200 5 times with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 185403.5
Subtract 2025 from 2200 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 10:
The number 405 fits into 1750 4 times, leaving a remainder of 130.
The next digit of our result is 4. 
Result so far: 185403.54
The remainder is 130 after subtracting 1620 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
When dividing 1300 by 405, we get 3 with a remainder of 85.
The next digit of our result is 3. 
Result so far: 185403.543
The remainder is 85 after subtracting 1215 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 12:
If we divide 850 by 405, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 185403.5432
If we take 810 away from 850, we end up 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.

Advancing to step 13:
If we divide 400 by 405, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 185403.5432
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 14:
If we divide 4000 by 405, we get 9 and a remainder of 355.
Use 9 as the next digit of our solution. 
Result so far: 185403.543209
If we subtract 3645 from 4000, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 15:
405 goes into 3550 8 times with a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 185403.5432098
Subtract 3240 from 3550 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 16:
405 goes into 3100 7 times with a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 185403.54320987
If we subtract 2835 from 3100, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

In conclusion, the division gives 185403.54320987 with a balance of 2.65e-07.
