We look at the division of 33676339 by 666 
The aim is to understand the frequency of 666 in 33676339.

On to step 1:
If we divide 3 by 666, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 666

Let's proceed to step 2:
666 can be fit into 33 0 times, resulting in a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 666

Let's proceed to step 3:
336 divided by 666 is 0 with a remainder of 336.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 336 and we're left with 336.
Include the next digit (7) from the dividend after 336, then repeat: 3367 / 666

Let's proceed to step 4:
If we divide 3367 by 666, we get 5 and a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 37 after subtracting 3330 from 3367.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 666

On to step 5:
376 divided by 666 is 0 with a remainder of 376.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 376, we get 376.
Grab the next digit (3) from the dividend, add it to 376, then carry on: 3763 / 666

Going ahead to step 6:
If we divide 3763 by 666, we get 5 and a remainder of 433.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Deduct 3330 from 3763 and we're left with 433.
Bring next digit (3) of the dividend behind the 433 and repeat the process: 4333 / 666

Let's proceed to step 7:
When dividing 4333 by 666, we get 6 with a remainder of 337.
Write down 6 as next digit of the result. 
Result so far: 5056.0
Subtract 3996 from 4333 to get 337.
Take the next digit (9) from the dividend and append it to 337, then repeat: 3379 / 666

Step 8:
The number 666 fits into 3379 5 times, leaving a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 50565.0
Deduct 3330 from 3379 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
666 can be fit into 490 0 times, resulting in a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 50565.0
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 10:
666 goes into 4900 7 times with a remainder of 238.
The next digit of our result is 7. 
Result so far: 50565.07
If we subtract 4662 from 4900, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 11:
The number 666 fits into 2380 3 times, leaving a remainder of 382.
Use 3 as the next digit of our solution. 
Result so far: 50565.073
Subtract 1998 from 2380 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 12:
666 can be fit into 3820 5 times, resulting in a remainder of 490.
Record the quotient 5 as the next digit in the result. 
Result so far: 50565.0735
Subtracting 3330 from 3820 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 13:
The number 666 fits into 4900 7 times, leaving a remainder of 238.
Use 7 as the next digit of our solution. 
Result so far: 50565.07357
If we take 4662 away from 4900, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 14:
666 goes into 2380 3 times with a remainder of 382.
Record the quotient 3 as the next digit in the result. 
Result so far: 50565.073573
Deduct 1998 from 2380 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 15:
666 goes into 3820 5 times with a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 50565.0735735
If we take 3330 away from 3820, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 16:
4900 divided by 666 is 7 with a remainder of 238.
The number 7 becomes the next digit in our result. 
Result so far: 50565.07357357
If we subtract 4662 from 4900, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

In conclusion, the division gives 50565.07357357 with a balance of 2.38e-07.
