We're dividing 77570212 by 752 
The aim is to understand the frequency of 752 in 77570212.

Advancing to step 1:
752 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 752

Moving on to step 2:
The number 752 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 752

On to step 3:
The number 752 fits into 775 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 752 away from 775, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 752

Advancing to step 4:
752 can be fit into 237 0 times, resulting in a remainder of 237.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 237, we get 237.
Take the next digit (0) from the dividend and append it to 237, then repeat: 2370 / 752

Advancing to step 5:
752 can be fit into 2370 3 times, resulting in a remainder of 114.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we subtract 2256 from 2370, we get 114.
Include the next digit (2) from the dividend after 114, then repeat: 1142 / 752

Step 6:
If we divide 1142 by 752, we get 1 and a remainder of 390.
Write down 1 as next digit of the result. 
Result so far: 1031.0
If we subtract 752 from 1142, we get 390.
Fetch the next digit (1) from the dividend, attach it to 390 and continue: 3901 / 752

Step 7:
3901 divided by 752 is 5 with a remainder of 141.
Use 5 as the next digit of our solution. 
Result so far: 10315.0
Deduct 3760 from 3901 and we're left with 141.
Include the next digit (2) from the dividend after 141, then repeat: 1412 / 752

Advancing to step 8:
If we divide 1412 by 752, we get 1 and a remainder of 660.
Write down 1 as next digit of the result. 
Result so far: 103151.0
Deduct 752 from 1412 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 9:
If we divide 6600 by 752, we get 8 and a remainder of 584.
The next digit of our result is 8. 
Result so far: 103151.8
Subtracting 6016 from 6600 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 10:
When dividing 5840 by 752, we get 7 with a remainder of 576.
The next digit of our result is 7. 
Result so far: 103151.87
Subtract 5264 from 5840 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 11:
The number 752 fits into 5760 7 times, leaving a remainder of 496.
Write down 7 as next digit of the result. 
Result so far: 103151.877
Subtract 5264 from 5760 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Our division results in 103151.877 with a remaining 0.0496.
