We're dividing 53172550 by 749 
The aim is to understand the frequency of 749 in 53172550.

Step 1:
749 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 749

Moving on to step 2:
749 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (1) from the dividend to 53 and continue with: 531 / 749

Step 3:
When dividing 531 by 749, we get 0 with a remainder of 531.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 531, we get 531.
Append the next digit (7) from the dividend to 531 and continue with: 5317 / 749

On to step 4:
When dividing 5317 by 749, we get 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5243 from 5317 leaves us with 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 749

Let's proceed to step 5:
749 goes into 742 0 times with a remainder of 742.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we take 0 away from 742, we end up with 742.
Bring next digit (5) of the dividend behind the 742 and repeat the process: 7425 / 749

On to step 6:
If we divide 7425 by 749, we get 9 and a remainder of 684.
Put 9 as the next digit of the answer. 
Result so far: 709.0
The remainder is 684 after subtracting 6741 from 7425.
Bring next digit (5) of the dividend behind the 684 and repeat the process: 6845 / 749

Moving on to step 7:
When dividing 6845 by 749, we get 9 with a remainder of 104.
Put 9 as the next digit of the answer. 
Result so far: 7099.0
If we subtract 6741 from 6845, we get 104.
Include the next digit (0) from the dividend after 104, then repeat: 1040 / 749

Step 8:
749 goes into 1040 1 times with a remainder of 291.
Use 1 as the next digit of our solution. 
Result so far: 70991.0
Subtracting 749 from 1040 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 9:
749 goes into 2910 3 times with a remainder of 663.
The number 3 becomes the next digit in our result. 
Result so far: 70991.3
Subtract 2247 from 2910 to get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

On to step 10:
The number 749 fits into 6630 8 times, leaving a remainder of 638.
Put 8 as the next digit of the answer. 
Result so far: 70991.38
If we take 5992 away from 6630, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

On to step 11:
When dividing 6380 by 749, we get 8 with a remainder of 388.
Record the quotient 8 as the next digit in the result. 
Result so far: 70991.388
Subtract 5992 from 6380 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

In conclusion, the division gives 70991.388 with a balance of 0.0388.
