We divide 81934113 by 666
The aim is to understand the frequency of 666 in 81934113.

Let's proceed to step 1:
The number 666 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 666

Going ahead to step 2:
666 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 666

Step 3:
819 divided by 666 is 1 with a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 153 after subtracting 666 from 819.
Bring next digit (3) of the dividend behind the 153 and repeat the process: 1533 / 666

Advancing to step 4:
If we divide 1533 by 666, we get 2 and a remainder of 201.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1332 from 1533 and we're left with 201.
Include the next digit (4) from the dividend after 201, then repeat: 2014 / 666

On to step 5:
666 can be fit into 2014 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 1998 from 2014 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 666

Moving on to step 6:
666 goes into 161 0 times with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 1230.0
If we subtract 0 from 161, we get 161.
Include the next digit (1) from the dividend after 161, then repeat: 1611 / 666

On to step 7:
When dividing 1611 by 666, we get 2 with a remainder of 279.
Use 2 as the next digit of our solution. 
Result so far: 12302.0
Subtracting 1332 from 1611 leaves us with 279.
Take the next digit (3) from the dividend and append it to 279, then repeat: 2793 / 666

Let's proceed to step 8:
If we divide 2793 by 666, we get 4 and a remainder of 129.
Use 4 as the next digit of our solution. 
Result so far: 123024.0
If we subtract 2664 from 2793, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Step 9:
1290 divided by 666 is 1 with a remainder of 624.
Put 1 as the next digit of the answer. 
Result so far: 123024.1
If we take 666 away from 1290, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 10:
666 goes into 6240 9 times with a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 123024.19
The remainder is 246 after subtracting 5994 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 11:
The number 666 fits into 2460 3 times, leaving a remainder of 462.
Put 3 as the next digit of the answer. 
Result so far: 123024.193
Deduct 1998 from 2460 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 12:
The number 666 fits into 4620 6 times, leaving a remainder of 624.
Put 6 as the next digit of the answer. 
Result so far: 123024.1936
If we take 3996 away from 4620, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 13:
If we divide 6240 by 666, we get 9 and a remainder of 246.
Record the quotient 9 as the next digit in the result. 
Result so far: 123024.19369
Deduct 5994 from 6240 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 14:
2460 divided by 666 is 3 with a remainder of 462.
The next digit of our result is 3. 
Result so far: 123024.193693
Subtracting 1998 from 2460 leaves us with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

On to step 15:
666 goes into 4620 6 times with a remainder of 624.
Put 6 as the next digit of the answer. 
Result so far: 123024.1936936
Subtracting 3996 from 4620 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 16:
6240 divided by 666 is 9 with a remainder of 246.
The next digit of our result is 9. 
Result so far: 123024.19369369
The remainder is 246 after subtracting 5994 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

After the division, we end up with 123024.19369369 and a remainder of 2.46e-07.
