We look at the division of 43001666 by 627 
The aim is to understand the frequency of 627 in 43001666.

Let's proceed to step 1:
If we divide 4 by 627, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 627

Step 2:
If we divide 43 by 627, we get 0 and a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 627

Step 3:
627 goes into 430 0 times with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 430 after subtracting 0 from 430.
Fetch the next digit (0) from the dividend, attach it to 430 and continue: 4300 / 627

Let's proceed to step 4:
4300 divided by 627 is 6 with a remainder of 538.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3762 from 4300, we get 538.
Grab the next digit (1) from the dividend, add it to 538, then carry on: 5381 / 627

Moving on to step 5:
627 goes into 5381 8 times with a remainder of 365.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 5016 away from 5381, we end up with 365.
Fetch the next digit (6) from the dividend, attach it to 365 and continue: 3656 / 627

Going ahead to step 6:
If we divide 3656 by 627, we get 5 and a remainder of 521.
Write down 5 as next digit of the result. 
Result so far: 685.0
If we take 3135 away from 3656, we end up with 521.
Bring next digit (6) of the dividend behind the 521 and repeat the process: 5216 / 627

On to step 7:
627 can be fit into 5216 8 times, resulting in a remainder of 200.
The next digit of our result is 8. 
Result so far: 6858.0
Deduct 5016 from 5216 and we're left with 200.
Include the next digit (6) from the dividend after 200, then repeat: 2006 / 627

Let's proceed to step 8:
627 goes into 2006 3 times with a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 68583.0
Deduct 1881 from 2006 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
627 goes into 1250 1 times with a remainder of 623.
The next digit of our result is 1. 
Result so far: 68583.1
If we take 627 away from 1250, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Moving on to step 10:
627 can be fit into 6230 9 times, resulting in a remainder of 587.
Use 9 as the next digit of our solution. 
Result so far: 68583.19
If we subtract 5643 from 6230, we get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Let's proceed to step 11:
5870 divided by 627 is 9 with a remainder of 227.
Record the quotient 9 as the next digit in the result. 
Result so far: 68583.199
Subtracting 5643 from 5870 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

After the division, we end up with 68583.199 and a remainder of 0.0227.
