54658418 ÷ 626 
The aim is to understand the frequency of 626 in 54658418.

Step 1:
When dividing 5 by 626, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 626

Moving on to step 2:
If we divide 54 by 626, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 626

Advancing to step 3:
626 goes into 546 0 times with a remainder of 546.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 546 after subtracting 0 from 546.
Fetch the next digit (5) from the dividend, attach it to 546 and continue: 5465 / 626

Step 4:
The number 626 fits into 5465 8 times, leaving a remainder of 457.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 5008 from 5465 leaves us with 457.
Take the next digit (8) from the dividend and append it to 457, then repeat: 4578 / 626

On to step 5:
If we divide 4578 by 626, we get 7 and a remainder of 196.
Use 7 as the next digit of our solution. 
Result so far: 87.0
The remainder is 196 after subtracting 4382 from 4578.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 626

Going ahead to step 6:
626 can be fit into 1964 3 times, resulting in a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 873.0
If we take 1878 away from 1964, we end up with 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 626

Moving on to step 7:
The number 626 fits into 861 1 times, leaving a remainder of 235.
The next digit of our result is 1. 
Result so far: 8731.0
If we subtract 626 from 861, we get 235.
Grab the next digit (8) from the dividend, add it to 235, then carry on: 2358 / 626

Let's proceed to step 8:
If we divide 2358 by 626, we get 3 and a remainder of 480.
Use 3 as the next digit of our solution. 
Result so far: 87313.0
Subtract 1878 from 2358 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 9:
626 goes into 4800 7 times with a remainder of 418.
The number 7 becomes the next digit in our result. 
Result so far: 87313.7
The remainder is 418 after subtracting 4382 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 10:
626 can be fit into 4180 6 times, resulting in a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 87313.76
Subtract 3756 from 4180 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
The number 626 fits into 4240 6 times, leaving a remainder of 484.
Put 6 as the next digit of the answer. 
Result so far: 87313.766
If we take 3756 away from 4240, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Our division results in 87313.766 with a remaining 0.0484.
