75931002 ÷ 628 
The aim is to understand the frequency of 628 in 75931002.

Let's proceed to step 1:
628 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 628

Let's proceed to step 2:
If we divide 75 by 628, we get 0 and a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 628

On to step 3:
628 goes into 759 1 times with a remainder of 131.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 628 from 759 leaves us with 131.
Bring next digit (3) of the dividend behind the 131 and repeat the process: 1313 / 628

Step 4:
When dividing 1313 by 628, we get 2 with a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1256 from 1313, we get 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 628

On to step 5:
628 goes into 571 0 times with a remainder of 571.
Write down 0 as next digit of the result. 
Result so far: 120.0
The remainder is 571 after subtracting 0 from 571.
Bring next digit (0) of the dividend behind the 571 and repeat the process: 5710 / 628

Moving on to step 6:
When dividing 5710 by 628, we get 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 1209.0
If we take 5652 away from 5710, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 628

Let's proceed to step 7:
628 goes into 580 0 times with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 12090.0
Deduct 0 from 580 and we're left with 580.
Fetch the next digit (2) from the dividend, attach it to 580 and continue: 5802 / 628

Advancing to step 8:
The number 628 fits into 5802 9 times, leaving a remainder of 150.
Use 9 as the next digit of our solution. 
Result so far: 120909.0
Subtract 5652 from 5802 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 9:
If we divide 1500 by 628, we get 2 and a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 120909.2
Deduct 1256 from 1500 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 10:
The number 628 fits into 2440 3 times, leaving a remainder of 556.
The number 3 becomes the next digit in our result. 
Result so far: 120909.23
Subtract 1884 from 2440 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Going ahead to step 11:
628 can be fit into 5560 8 times, resulting in a remainder of 536.
Use 8 as the next digit of our solution. 
Result so far: 120909.238
Subtracting 5024 from 5560 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.

Moving on to step 12:
The number 628 fits into 5360 8 times, leaving a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 120909.2388
If we subtract 5024 from 5360, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 120909.2388, with a leftover of 0.00336.
