Let's divide 27612528 by 641
The aim is to understand the frequency of 641 in 27612528.

Step 1:
When dividing 2 by 641, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 641

On to step 2:
641 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 641

Going ahead to step 3:
641 goes into 276 0 times with a remainder of 276.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 276 and we're left with 276.
Append the next digit (1) from the dividend to 276 and continue with: 2761 / 641

Step 4:
If we divide 2761 by 641, we get 4 and a remainder of 197.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2564 from 2761, we get 197.
Append the next digit (2) from the dividend to 197 and continue with: 1972 / 641

Going ahead to step 5:
The number 641 fits into 1972 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtract 1923 from 1972 to get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 641

Let's proceed to step 6:
When dividing 495 by 641, we get 0 with a remainder of 495.
Use 0 as the next digit of our solution. 
Result so far: 430.0
If we take 0 away from 495, we end up with 495.
Include the next digit (2) from the dividend after 495, then repeat: 4952 / 641

Going ahead to step 7:
641 can be fit into 4952 7 times, resulting in a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 4307.0
Deduct 4487 from 4952 and we're left with 465.
Bring next digit (8) of the dividend behind the 465 and repeat the process: 4658 / 641

Moving on to step 8:
641 can be fit into 4658 7 times, resulting in a remainder of 171.
The next digit of our result is 7. 
Result so far: 43077.0
The remainder is 171 after subtracting 4487 from 4658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
If we divide 1710 by 641, we get 2 and a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 43077.2
The remainder is 428 after subtracting 1282 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 10:
4280 divided by 641 is 6 with a remainder of 434.
Record the quotient 6 as the next digit in the result. 
Result so far: 43077.26
Subtract 3846 from 4280 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 11:
If we divide 4340 by 641, we get 6 and a remainder of 494.
Record the quotient 6 as the next digit in the result. 
Result so far: 43077.266
If we take 3846 away from 4340, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

In conclusion, the division gives 43077.266 with a balance of 0.0494.
