We look at the division of 50929744 by 618 
The aim is to understand the frequency of 618 in 50929744.

On to step 1:
618 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 618

Step 2:
The number 618 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 618

On to step 3:
618 can be fit into 509 0 times, resulting in a remainder of 509.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 509, we end up with 509.
Include the next digit (2) from the dividend after 509, then repeat: 5092 / 618

Advancing to step 4:
If we divide 5092 by 618, we get 8 and a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 4944 from 5092 leaves us with 148.
Bring next digit (9) of the dividend behind the 148 and repeat the process: 1489 / 618

Advancing to step 5:
618 goes into 1489 2 times with a remainder of 253.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 1236 from 1489 leaves us with 253.
Bring next digit (7) of the dividend behind the 253 and repeat the process: 2537 / 618

Let's proceed to step 6:
618 goes into 2537 4 times with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 824.0
Subtract 2472 from 2537 to get 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 618

Advancing to step 7:
618 can be fit into 654 1 times, resulting in a remainder of 36.
The next digit of our result is 1. 
Result so far: 8241.0
If we subtract 618 from 654, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 618

Let's proceed to step 8:
The number 618 fits into 364 0 times, leaving a remainder of 364.
The number 0 becomes the next digit in our result. 
Result so far: 82410.0
If we subtract 0 from 364, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 9:
When dividing 3640 by 618, we get 5 with a remainder of 550.
Put 5 as the next digit of the answer. 
Result so far: 82410.5
Subtract 3090 from 3640 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
If we divide 5500 by 618, we get 8 and a remainder of 556.
Use 8 as the next digit of our solution. 
Result so far: 82410.58
Subtracting 4944 from 5500 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 11:
The number 618 fits into 5560 8 times, leaving a remainder of 616.
Put 8 as the next digit of the answer. 
Result so far: 82410.588
Subtracting 4944 from 5560 leaves us with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

After the division, we end up with 82410.588 and a remainder of 0.0616.
