89907036 divided by 628 
The aim is to understand the frequency of 628 in 89907036.

On to step 1:
The number 628 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 628

Going ahead to step 2:
The number 628 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Fetch the next digit (9) from the dividend, attach it to 89 and continue: 899 / 628

Advancing to step 3:
When dividing 899 by 628, we get 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 628 from 899 leaves us with 271.
Include the next digit (0) from the dividend after 271, then repeat: 2710 / 628

Step 4:
628 can be fit into 2710 4 times, resulting in a remainder of 198.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2512 from 2710 and we're left with 198.
Fetch the next digit (7) from the dividend, attach it to 198 and continue: 1987 / 628

Let's proceed to step 5:
When dividing 1987 by 628, we get 3 with a remainder of 103.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Deduct 1884 from 1987 and we're left with 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 628

Going ahead to step 6:
If we divide 1030 by 628, we get 1 and a remainder of 402.
The number 1 becomes the next digit in our result. 
Result so far: 1431.0
If we subtract 628 from 1030, we get 402.
Include the next digit (3) from the dividend after 402, then repeat: 4023 / 628

On to step 7:
If we divide 4023 by 628, we get 6 and a remainder of 255.
Write down 6 as next digit of the result. 
Result so far: 14316.0
If we subtract 3768 from 4023, we get 255.
Bring next digit (6) of the dividend behind the 255 and repeat the process: 2556 / 628

Moving on to step 8:
When dividing 2556 by 628, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 143164.0
Subtract 2512 from 2556 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
628 can be fit into 440 0 times, resulting in a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 143164.0
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
4400 divided by 628 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 143164.07
If we subtract 4396 from 4400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 628 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 143164.07
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
628 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 143164.07
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 143164.07 with a remaining 0.004.
