3665595 ÷ 178 
The aim is to understand the frequency of 178 in 3665595.

Let's proceed to step 1:
178 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 178

Advancing to step 2:
When dividing 36 by 178, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 178

Moving on to step 3:
When dividing 366 by 178, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 356 from 366 leaves us with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 178

Step 4:
178 can be fit into 105 0 times, resulting in a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 105 to get 105.
Append the next digit (5) from the dividend to 105 and continue with: 1055 / 178

Advancing to step 5:
1055 divided by 178 is 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 205.0
Subtracting 890 from 1055 leaves us with 165.
Take the next digit (9) from the dividend and append it to 165, then repeat: 1659 / 178

Let's proceed to step 6:
The number 178 fits into 1659 9 times, leaving a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 2059.0
If we subtract 1602 from 1659, we get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 178

Let's proceed to step 7:
178 goes into 575 3 times with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 20593.0
If we take 534 away from 575, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
The number 178 fits into 410 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 20593.2
If we take 356 away from 410, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 178, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 20593.23
Subtracting 534 from 540 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
60 divided by 178 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 20593.23
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 178 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 20593.2303
Subtracting 534 from 600 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
178 can be fit into 660 3 times, resulting in a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 20593.23033
If we take 534 away from 660, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 20593.23033, with a leftover of 0.000126.
