We're dividing 35976995 by 405 
The aim is to understand the frequency of 405 in 35976995.

Advancing to step 1:
If we divide 3 by 405, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 405

Step 2:
The number 405 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 405

Moving on to step 3:
The number 405 fits into 359 0 times, leaving a remainder of 359.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 359 leaves us with 359.
Take the next digit (7) from the dividend and append it to 359, then repeat: 3597 / 405

On to step 4:
If we divide 3597 by 405, we get 8 and a remainder of 357.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 3240 from 3597 leaves us with 357.
Append the next digit (6) from the dividend to 357 and continue with: 3576 / 405

Let's proceed to step 5:
The number 405 fits into 3576 8 times, leaving a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtracting 3240 from 3576 leaves us with 336.
Grab the next digit (9) from the dividend, add it to 336, then carry on: 3369 / 405

Moving on to step 6:
3369 divided by 405 is 8 with a remainder of 129.
Put 8 as the next digit of the answer. 
Result so far: 888.0
If we subtract 3240 from 3369, we get 129.
Append the next digit (9) from the dividend to 129 and continue with: 1299 / 405

On to step 7:
When dividing 1299 by 405, we get 3 with a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 8883.0
The remainder is 84 after subtracting 1215 from 1299.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 405

Going ahead to step 8:
845 divided by 405 is 2 with a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 88832.0
Deduct 810 from 845 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
350 divided by 405 is 0 with a remainder of 350.
The next digit of our result is 0. 
Result so far: 88832.0
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 10:
If we divide 3500 by 405, we get 8 and a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 88832.08
If we subtract 3240 from 3500, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
2600 divided by 405 is 6 with a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 88832.086
If we subtract 2430 from 2600, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 12:
405 can be fit into 1700 4 times, resulting in a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 88832.0864
Subtracting 1620 from 1700 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
800 divided by 405 is 1 with a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 88832.08641
Deduct 405 from 800 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 14:
The number 405 fits into 3950 9 times, leaving a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 88832.086419
Subtract 3645 from 3950 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 15:
3050 divided by 405 is 7 with a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 88832.0864197
Subtract 2835 from 3050 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 16:
405 goes into 2150 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 88832.08641975
If we subtract 2025 from 2150, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 88832.08641975 with a remaining 1.25e-07.
