Let's divide 85544271 by 666
The aim is to understand the frequency of 666 in 85544271.

Advancing to step 1:
When dividing 8 by 666, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 666

Moving on to step 2:
When dividing 85 by 666, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 666

Let's proceed to step 3:
855 divided by 666 is 1 with a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 189 after subtracting 666 from 855.
Append the next digit (4) from the dividend to 189 and continue with: 1894 / 666

On to step 4:
If we divide 1894 by 666, we get 2 and a remainder of 562.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 562 after subtracting 1332 from 1894.
Fetch the next digit (4) from the dividend, attach it to 562 and continue: 5624 / 666

Going ahead to step 5:
666 goes into 5624 8 times with a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Deduct 5328 from 5624 and we're left with 296.
Grab the next digit (2) from the dividend, add it to 296, then carry on: 2962 / 666

Going ahead to step 6:
2962 divided by 666 is 4 with a remainder of 298.
Record the quotient 4 as the next digit in the result. 
Result so far: 1284.0
If we take 2664 away from 2962, we end up with 298.
Take the next digit (7) from the dividend and append it to 298, then repeat: 2987 / 666

Moving on to step 7:
2987 divided by 666 is 4 with a remainder of 323.
Put 4 as the next digit of the answer. 
Result so far: 12844.0
If we take 2664 away from 2987, we end up with 323.
Take the next digit (1) from the dividend and append it to 323, then repeat: 3231 / 666

On to step 8:
3231 divided by 666 is 4 with a remainder of 567.
The next digit of our result is 4. 
Result so far: 128444.0
The remainder is 567 after subtracting 2664 from 3231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

On to step 9:
5670 divided by 666 is 8 with a remainder of 342.
Put 8 as the next digit of the answer. 
Result so far: 128444.8
If we take 5328 away from 5670, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 10:
When dividing 3420 by 666, we get 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 128444.85
If we subtract 3330 from 3420, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
666 goes into 900 1 times with a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 128444.851
If we subtract 666 from 900, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 12:
666 goes into 2340 3 times with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 128444.8513
The remainder is 342 after subtracting 1998 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 13:
The number 666 fits into 3420 5 times, leaving a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 128444.85135
Subtracting 3330 from 3420 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
666 can be fit into 900 1 times, resulting in a remainder of 234.
Use 1 as the next digit of our solution. 
Result so far: 128444.851351
If we take 666 away from 900, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 15:
When dividing 2340 by 666, we get 3 with a remainder of 342.
Use 3 as the next digit of our solution. 
Result so far: 128444.8513513
The remainder is 342 after subtracting 1998 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 16:
666 goes into 3420 5 times with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 128444.85135135
The remainder is 90 after subtracting 3330 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The final outcome is 128444.85135135, with a leftover of 9e-08.
