42975081 divided by 628 
The aim is to understand the frequency of 628 in 42975081.

Advancing to step 1:
If we divide 4 by 628, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 628

On to step 2:
When dividing 42 by 628, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 628

Going ahead to step 3:
628 can be fit into 429 0 times, resulting in a remainder of 429.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 429, we get 429.
Take the next digit (7) from the dividend and append it to 429, then repeat: 4297 / 628

Advancing to step 4:
4297 divided by 628 is 6 with a remainder of 529.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 529 after subtracting 3768 from 4297.
Include the next digit (5) from the dividend after 529, then repeat: 5295 / 628

Going ahead to step 5:
628 can be fit into 5295 8 times, resulting in a remainder of 271.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 271 after subtracting 5024 from 5295.
Grab the next digit (0) from the dividend, add it to 271, then carry on: 2710 / 628

Let's proceed to step 6:
When dividing 2710 by 628, we get 4 with a remainder of 198.
The number 4 becomes the next digit in our result. 
Result so far: 684.0
Deduct 2512 from 2710 and we're left with 198.
Take the next digit (8) from the dividend and append it to 198, then repeat: 1988 / 628

Moving on to step 7:
1988 divided by 628 is 3 with a remainder of 104.
Write down 3 as next digit of the result. 
Result so far: 6843.0
Subtracting 1884 from 1988 leaves us with 104.
Append the next digit (1) from the dividend to 104 and continue with: 1041 / 628

Moving on to step 8:
1041 divided by 628 is 1 with a remainder of 413.
Record the quotient 1 as the next digit in the result. 
Result so far: 68431.0
Subtract 628 from 1041 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Moving on to step 9:
The number 628 fits into 4130 6 times, leaving a remainder of 362.
The next digit of our result is 6. 
Result so far: 68431.6
Deduct 3768 from 4130 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 10:
The number 628 fits into 3620 5 times, leaving a remainder of 480.
Record the quotient 5 as the next digit in the result. 
Result so far: 68431.65
If we take 3140 away from 3620, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
When dividing 4800 by 628, we get 7 with a remainder of 404.
The number 7 becomes the next digit in our result. 
Result so far: 68431.657
The remainder is 404 after subtracting 4396 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 12:
If we divide 4040 by 628, we get 6 and a remainder of 272.
The next digit of our result is 6. 
Result so far: 68431.6576
Subtract 3768 from 4040 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 13:
2720 divided by 628 is 4 with a remainder of 208.
Put 4 as the next digit of the answer. 
Result so far: 68431.65764
Deduct 2512 from 2720 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 14:
When dividing 2080 by 628, we get 3 with a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 68431.657643
The remainder is 196 after subtracting 1884 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 15:
When dividing 1960 by 628, we get 3 with a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 68431.6576433
Subtracting 1884 from 1960 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 68431.6576433 and a remainder of 7.6e-07.
