We look at the division of 29844569 by 749 
The aim is to understand the frequency of 749 in 29844569.

Step 1:
2 divided by 749 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 749

Advancing to step 2:
749 goes into 29 0 times with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 749

Moving on to step 3:
When dividing 298 by 749, we get 0 with a remainder of 298.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 298 after subtracting 0 from 298.
Take the next digit (4) from the dividend and append it to 298, then repeat: 2984 / 749

Advancing to step 4:
If we divide 2984 by 749, we get 3 and a remainder of 737.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2247 away from 2984, we end up with 737.
Include the next digit (4) from the dividend after 737, then repeat: 7374 / 749

Going ahead to step 5:
When dividing 7374 by 749, we get 9 with a remainder of 633.
The next digit of our result is 9. 
Result so far: 39.0
If we take 6741 away from 7374, we end up with 633.
Bring next digit (5) of the dividend behind the 633 and repeat the process: 6335 / 749

Step 6:
6335 divided by 749 is 8 with a remainder of 343.
Write down 8 as next digit of the result. 
Result so far: 398.0
Subtracting 5992 from 6335 leaves us with 343.
Include the next digit (6) from the dividend after 343, then repeat: 3436 / 749

Advancing to step 7:
When dividing 3436 by 749, we get 4 with a remainder of 440.
Record the quotient 4 as the next digit in the result. 
Result so far: 3984.0
Subtract 2996 from 3436 to get 440.
Fetch the next digit (9) from the dividend, attach it to 440 and continue: 4409 / 749

Advancing to step 8:
If we divide 4409 by 749, we get 5 and a remainder of 664.
Put 5 as the next digit of the answer. 
Result so far: 39845.0
Deduct 3745 from 4409 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 9:
The number 749 fits into 6640 8 times, leaving a remainder of 648.
The number 8 becomes the next digit in our result. 
Result so far: 39845.8
Subtract 5992 from 6640 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 10:
The number 749 fits into 6480 8 times, leaving a remainder of 488.
The number 8 becomes the next digit in our result. 
Result so far: 39845.88
Subtract 5992 from 6480 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

After the division, we end up with 39845.88 and a remainder of 0.488.
