93136097 ÷ 405 
The aim is to understand the frequency of 405 in 93136097.

Going ahead to step 1:
If we divide 9 by 405, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 405

Going ahead to step 2:
93 divided by 405 is 0 with a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Bring next digit (1) of the dividend behind the 93 and repeat the process: 931 / 405

On to step 3:
931 divided by 405 is 2 with a remainder of 121.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 810 from 931 leaves us with 121.
Append the next digit (3) from the dividend to 121 and continue with: 1213 / 405

Moving on to step 4:
405 can be fit into 1213 2 times, resulting in a remainder of 403.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 403 after subtracting 810 from 1213.
Bring next digit (6) of the dividend behind the 403 and repeat the process: 4036 / 405

Advancing to step 5:
When dividing 4036 by 405, we get 9 with a remainder of 391.
The next digit of our result is 9. 
Result so far: 229.0
Subtract 3645 from 4036 to get 391.
Grab the next digit (0) from the dividend, add it to 391, then carry on: 3910 / 405

Moving on to step 6:
3910 divided by 405 is 9 with a remainder of 265.
Put 9 as the next digit of the answer. 
Result so far: 2299.0
Deduct 3645 from 3910 and we're left with 265.
Append the next digit (9) from the dividend to 265 and continue with: 2659 / 405

Step 7:
405 can be fit into 2659 6 times, resulting in a remainder of 229.
Record the quotient 6 as the next digit in the result. 
Result so far: 22996.0
If we take 2430 away from 2659, we end up with 229.
Bring next digit (7) of the dividend behind the 229 and repeat the process: 2297 / 405

Advancing to step 8:
405 goes into 2297 5 times with a remainder of 272.
Write down 5 as next digit of the result. 
Result so far: 229965.0
If we subtract 2025 from 2297, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 9:
405 goes into 2720 6 times with a remainder of 290.
Write down 6 as next digit of the result. 
Result so far: 229965.6
If we subtract 2430 from 2720, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
405 goes into 2900 7 times with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 229965.67
Deduct 2835 from 2900 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 11:
If we divide 650 by 405, we get 1 and a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 229965.671
If we subtract 405 from 650, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 12:
405 can be fit into 2450 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 229965.6716
Subtract 2430 from 2450 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
200 divided by 405 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 229965.6716
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
When dividing 2000 by 405, we get 4 with a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 229965.671604
Subtract 1620 from 2000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 15:
405 goes into 3800 9 times with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 229965.6716049
If we subtract 3645 from 3800, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 16:
The number 405 fits into 1550 3 times, leaving a remainder of 335.
Put 3 as the next digit of the answer. 
Result so far: 229965.67160493
If we subtract 1215 from 1550, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final result is 229965.67160493 with a remainder of 3.35e-07.
