5133196 ÷ 405 
The aim is to understand the frequency of 405 in 5133196.

Going ahead to step 1:
5 divided by 405 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 405

Let's proceed to step 2:
When dividing 51 by 405, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 405

On to step 3:
When dividing 513 by 405, we get 1 with a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 405 from 513 to get 108.
Fetch the next digit (3) from the dividend, attach it to 108 and continue: 1083 / 405

Going ahead to step 4:
405 can be fit into 1083 2 times, resulting in a remainder of 273.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 810 away from 1083, we end up with 273.
Grab the next digit (1) from the dividend, add it to 273, then carry on: 2731 / 405

Moving on to step 5:
If we divide 2731 by 405, we get 6 and a remainder of 301.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 2430 away from 2731, we end up with 301.
Grab the next digit (9) from the dividend, add it to 301, then carry on: 3019 / 405

On to step 6:
405 can be fit into 3019 7 times, resulting in a remainder of 184.
Use 7 as the next digit of our solution. 
Result so far: 1267.0
The remainder is 184 after subtracting 2835 from 3019.
Include the next digit (6) from the dividend after 184, then repeat: 1846 / 405

On to step 7:
405 can be fit into 1846 4 times, resulting in a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 12674.0
Deduct 1620 from 1846 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 8:
405 can be fit into 2260 5 times, resulting in a remainder of 235.
Put 5 as the next digit of the answer. 
Result so far: 12674.5
Deduct 2025 from 2260 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 9:
2350 divided by 405 is 5 with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 12674.55
Subtracting 2025 from 2350 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Our division results in 12674.55 with a remaining 0.325.
