54548426 ÷ 818 
The aim is to understand the frequency of 818 in 54548426.

Let's proceed to step 1:
5 divided by 818 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 818

On to step 2:
818 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 818

Advancing to step 3:
818 can be fit into 545 0 times, resulting in a remainder of 545.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 545, we get 545.
Append the next digit (4) from the dividend to 545 and continue with: 5454 / 818

Going ahead to step 4:
The number 818 fits into 5454 6 times, leaving a remainder of 546.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 4908 away from 5454, we end up with 546.
Grab the next digit (8) from the dividend, add it to 546, then carry on: 5468 / 818

Step 5:
818 goes into 5468 6 times with a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we subtract 4908 from 5468, we get 560.
Bring next digit (4) of the dividend behind the 560 and repeat the process: 5604 / 818

Step 6:
The number 818 fits into 5604 6 times, leaving a remainder of 696.
The next digit of our result is 6. 
Result so far: 666.0
If we take 4908 away from 5604, we end up with 696.
Take the next digit (2) from the dividend and append it to 696, then repeat: 6962 / 818

On to step 7:
818 can be fit into 6962 8 times, resulting in a remainder of 418.
Write down 8 as next digit of the result. 
Result so far: 6668.0
If we subtract 6544 from 6962, we get 418.
Include the next digit (6) from the dividend after 418, then repeat: 4186 / 818

Advancing to step 8:
The number 818 fits into 4186 5 times, leaving a remainder of 96.
The number 5 becomes the next digit in our result. 
Result so far: 66685.0
If we take 4090 away from 4186, 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.

Going ahead to step 9:
818 goes into 960 1 times with a remainder of 142.
The next digit of our result is 1. 
Result so far: 66685.1
Deduct 818 from 960 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 10:
818 goes into 1420 1 times with a remainder of 602.
Write down 1 as next digit of the result. 
Result so far: 66685.11
The remainder is 602 after subtracting 818 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

The final result is 66685.11 with a remainder of 0.602.
