We look at the division of 18003282 by 436 
The aim is to understand the frequency of 436 in 18003282.

Going ahead to step 1:
436 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 436

Step 2:
The number 436 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 436

Advancing to step 3:
436 can be fit into 180 0 times, resulting in a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 180 and we're left with 180.
Fetch the next digit (0) from the dividend, attach it to 180 and continue: 1800 / 436

Step 4:
The number 436 fits into 1800 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1744 from 1800 to get 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 436

On to step 5:
436 can be fit into 563 1 times, resulting in a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 436 away from 563, we end up with 127.
Grab the next digit (2) from the dividend, add it to 127, then carry on: 1272 / 436

Moving on to step 6:
When dividing 1272 by 436, we get 2 with a remainder of 400.
The number 2 becomes the next digit in our result. 
Result so far: 412.0
If we subtract 872 from 1272, we get 400.
Append the next digit (8) from the dividend to 400 and continue with: 4008 / 436

Going ahead to step 7:
436 goes into 4008 9 times with a remainder of 84.
Write down 9 as next digit of the result. 
Result so far: 4129.0
Subtract 3924 from 4008 to get 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 436

Going ahead to step 8:
436 goes into 842 1 times with a remainder of 406.
The next digit of our result is 1. 
Result so far: 41291.0
Deduct 436 from 842 and we're left with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 9:
When dividing 4060 by 436, we get 9 with a remainder of 136.
The next digit of our result is 9. 
Result so far: 41291.9
If we take 3924 away from 4060, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 10:
If we divide 1360 by 436, we get 3 and a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 41291.93
The remainder is 52 after subtracting 1308 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
When dividing 520 by 436, we get 1 with a remainder of 84.
Record the quotient 1 as the next digit in the result. 
Result so far: 41291.931
Deduct 436 from 520 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
If we divide 840 by 436, we get 1 and a remainder of 404.
Write down 1 as next digit of the result. 
Result so far: 41291.9311
Subtracting 436 from 840 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 41291.9311 and a remainder of 0.00404.
