We look at the division of 7584186 by 436 
The aim is to understand the frequency of 436 in 7584186.

Step 1:
When dividing 7 by 436, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 436

Let's proceed to step 2:
436 goes into 75 0 times with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 436

Going ahead to step 3:
436 goes into 758 1 times with a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 436 from 758, we get 322.
Take the next digit (4) from the dividend and append it to 322, then repeat: 3224 / 436

On to step 4:
436 goes into 3224 7 times with a remainder of 172.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3052 away from 3224, we end up with 172.
Take the next digit (1) from the dividend and append it to 172, then repeat: 1721 / 436

On to step 5:
The number 436 fits into 1721 3 times, leaving a remainder of 413.
Put 3 as the next digit of the answer. 
Result so far: 173.0
If we take 1308 away from 1721, we end up with 413.
Bring next digit (8) of the dividend behind the 413 and repeat the process: 4138 / 436

On to step 6:
The number 436 fits into 4138 9 times, leaving a remainder of 214.
The next digit of our result is 9. 
Result so far: 1739.0
Subtract 3924 from 4138 to get 214.
Fetch the next digit (6) from the dividend, attach it to 214 and continue: 2146 / 436

Let's proceed to step 7:
436 can be fit into 2146 4 times, resulting in a remainder of 402.
The number 4 becomes the next digit in our result. 
Result so far: 17394.0
Subtracting 1744 from 2146 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 8:
436 can be fit into 4020 9 times, resulting in a remainder of 96.
Use 9 as the next digit of our solution. 
Result so far: 17394.9
If we take 3924 away from 4020, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
If we divide 960 by 436, we get 2 and a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 17394.92
Subtracting 872 from 960 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 10:
If we divide 880 by 436, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 17394.922
The remainder is 8 after subtracting 872 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 17394.922 and a remainder of 0.0008.
