Let's divide 27552181 by 628
The aim is to understand the frequency of 628 in 27552181.

On to step 1:
628 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 628

Moving on to step 2:
If we divide 27 by 628, we get 0 and a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 628

Moving on to step 3:
628 goes into 275 0 times with a remainder of 275.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 275, we get 275.
Include the next digit (5) from the dividend after 275, then repeat: 2755 / 628

On to step 4:
The number 628 fits into 2755 4 times, leaving a remainder of 243.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 2512 from 2755 and we're left with 243.
Include the next digit (2) from the dividend after 243, then repeat: 2432 / 628

Let's proceed to step 5:
628 can be fit into 2432 3 times, resulting in a remainder of 548.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 1884 from 2432 leaves us with 548.
Grab the next digit (1) from the dividend, add it to 548, then carry on: 5481 / 628

Moving on to step 6:
628 can be fit into 5481 8 times, resulting in a remainder of 457.
Put 8 as the next digit of the answer. 
Result so far: 438.0
If we subtract 5024 from 5481, we get 457.
Grab the next digit (8) from the dividend, add it to 457, then carry on: 4578 / 628

Step 7:
4578 divided by 628 is 7 with a remainder of 182.
Put 7 as the next digit of the answer. 
Result so far: 4387.0
The remainder is 182 after subtracting 4396 from 4578.
Append the next digit (1) from the dividend to 182 and continue with: 1821 / 628

Let's proceed to step 8:
If we divide 1821 by 628, we get 2 and a remainder of 565.
The number 2 becomes the next digit in our result. 
Result so far: 43872.0
If we take 1256 away from 1821, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Advancing to step 9:
628 can be fit into 5650 8 times, resulting in a remainder of 626.
Record the quotient 8 as the next digit in the result. 
Result so far: 43872.8
Subtracting 5024 from 5650 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 10:
6260 divided by 628 is 9 with a remainder of 608.
Use 9 as the next digit of our solution. 
Result so far: 43872.89
If we subtract 5652 from 6260, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 11:
When dividing 6080 by 628, we get 9 with a remainder of 428.
The number 9 becomes the next digit in our result. 
Result so far: 43872.899
Deduct 5652 from 6080 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The quotient of the division is 43872.899, and the remainder is 0.0428.
