We look at the division of 660502 by 752 
The aim is to understand the frequency of 752 in 660502.

Advancing to step 1:
752 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 752

Step 2:
66 divided by 752 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 752

Let's proceed to step 3:
752 can be fit into 660 0 times, resulting in a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 660 after subtracting 0 from 660.
Fetch the next digit (5) from the dividend, attach it to 660 and continue: 6605 / 752

Advancing to step 4:
If we divide 6605 by 752, we get 8 and a remainder of 589.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6016 from 6605 and we're left with 589.
Take the next digit (0) from the dividend and append it to 589, then repeat: 5890 / 752

Moving on to step 5:
752 can be fit into 5890 7 times, resulting in a remainder of 626.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 626 after subtracting 5264 from 5890.
Append the next digit (2) from the dividend to 626 and continue with: 6262 / 752

Step 6:
752 goes into 6262 8 times with a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 878.0
If we subtract 6016 from 6262, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 7:
752 goes into 2460 3 times with a remainder of 204.
Use 3 as the next digit of our solution. 
Result so far: 878.3
The remainder is 204 after subtracting 2256 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 8:
2040 divided by 752 is 2 with a remainder of 536.
Record the quotient 2 as the next digit in the result. 
Result so far: 878.32
Subtracting 1504 from 2040 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 9:
752 goes into 5360 7 times with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 878.327
Subtracting 5264 from 5360 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 10:
752 goes into 960 1 times with a remainder of 208.
Use 1 as the next digit of our solution. 
Result so far: 878.3271
The remainder is 208 after subtracting 752 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 11:
The number 752 fits into 2080 2 times, leaving a remainder of 576.
The next digit of our result is 2. 
Result so far: 878.32712
Subtracting 1504 from 2080 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 12:
752 goes into 5760 7 times with a remainder of 496.
The number 7 becomes the next digit in our result. 
Result so far: 878.327127
The remainder is 496 after subtracting 5264 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 13:
The number 752 fits into 4960 6 times, leaving a remainder of 448.
Write down 6 as next digit of the result. 
Result so far: 878.3271276
Deduct 4512 from 4960 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 14:
When dividing 4480 by 752, we get 5 with a remainder of 720.
Put 5 as the next digit of the answer. 
Result so far: 878.32712765
If we subtract 3760 from 4480, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Our division results in 878.32712765 with a remaining 7.2e-07.
