69867045 divided by 666 
The aim is to understand the frequency of 666 in 69867045.

Advancing to step 1:
6 divided by 666 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 666

Moving on to step 2:
If we divide 69 by 666, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 666

On to step 3:
666 can be fit into 698 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 666 away from 698, we end up with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 666

Going ahead to step 4:
When dividing 326 by 666, we get 0 with a remainder of 326.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 326 leaves us with 326.
Append the next digit (7) from the dividend to 326 and continue with: 3267 / 666

On to step 5:
666 goes into 3267 4 times with a remainder of 603.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 2664 from 3267, we get 603.
Take the next digit (0) from the dividend and append it to 603, then repeat: 6030 / 666

On to step 6:
If we divide 6030 by 666, we get 9 and a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 1049.0
If we subtract 5994 from 6030, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 666

Moving on to step 7:
If we divide 364 by 666, we get 0 and a remainder of 364.
Record the quotient 0 as the next digit in the result. 
Result so far: 10490.0
Subtracting 0 from 364 leaves us with 364.
Grab the next digit (5) from the dividend, add it to 364, then carry on: 3645 / 666

On to step 8:
666 can be fit into 3645 5 times, resulting in a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 104905.0
Subtracting 3330 from 3645 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 9:
666 goes into 3150 4 times with a remainder of 486.
Write down 4 as next digit of the result. 
Result so far: 104905.4
Deduct 2664 from 3150 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 10:
When dividing 4860 by 666, we get 7 with a remainder of 198.
Record the quotient 7 as the next digit in the result. 
Result so far: 104905.47
The remainder is 198 after subtracting 4662 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 11:
If we divide 1980 by 666, we get 2 and a remainder of 648.
Put 2 as the next digit of the answer. 
Result so far: 104905.472
Subtract 1332 from 1980 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Advancing to step 12:
666 goes into 6480 9 times with a remainder of 486.
The number 9 becomes the next digit in our result. 
Result so far: 104905.4729
Subtracting 5994 from 6480 leaves us with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Advancing to step 13:
4860 divided by 666 is 7 with a remainder of 198.
Use 7 as the next digit of our solution. 
Result so far: 104905.47297
The remainder is 198 after subtracting 4662 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 14:
666 can be fit into 1980 2 times, resulting in a remainder of 648.
Record the quotient 2 as the next digit in the result. 
Result so far: 104905.472972
The remainder is 648 after subtracting 1332 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 15:
If we divide 6480 by 666, we get 9 and a remainder of 486.
Write down 9 as next digit of the result. 
Result so far: 104905.4729729
Subtract 5994 from 6480 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 16:
666 goes into 4860 7 times with a remainder of 198.
The number 7 becomes the next digit in our result. 
Result so far: 104905.47297297
The remainder is 198 after subtracting 4662 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Our division results in 104905.47297297 with a remaining 1.98e-07.
