We look at the division of 68518112 by 749 
The aim is to understand the frequency of 749 in 68518112.

Going ahead to step 1:
749 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 749

Let's proceed to step 2:
749 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 749

On to step 3:
749 can be fit into 685 0 times, resulting in a remainder of 685.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 685 to get 685.
Bring next digit (1) of the dividend behind the 685 and repeat the process: 6851 / 749

Step 4:
749 can be fit into 6851 9 times, resulting in a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 6741 from 6851, we get 110.
Fetch the next digit (8) from the dividend, attach it to 110 and continue: 1108 / 749

Going ahead to step 5:
The number 749 fits into 1108 1 times, leaving a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 749 from 1108 to get 359.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 749

Let's proceed to step 6:
3591 divided by 749 is 4 with a remainder of 595.
The number 4 becomes the next digit in our result. 
Result so far: 914.0
If we take 2996 away from 3591, we end up with 595.
Append the next digit (1) from the dividend to 595 and continue with: 5951 / 749

Advancing to step 7:
749 can be fit into 5951 7 times, resulting in a remainder of 708.
The next digit of our result is 7. 
Result so far: 9147.0
Deduct 5243 from 5951 and we're left with 708.
Take the next digit (2) from the dividend and append it to 708, then repeat: 7082 / 749

Advancing to step 8:
If we divide 7082 by 749, we get 9 and a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 91479.0
If we take 6741 away from 7082, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 9:
749 goes into 3410 4 times with a remainder of 414.
Put 4 as the next digit of the answer. 
Result so far: 91479.4
If we take 2996 away from 3410, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 10:
749 goes into 4140 5 times with a remainder of 395.
The next digit of our result is 5. 
Result so far: 91479.45
If we take 3745 away from 4140, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 11:
When dividing 3950 by 749, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 91479.455
Subtract 3745 from 3950 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 91479.455 and a remainder of 0.0205.
