Let's divide 70151280 by 666
The aim is to understand the frequency of 666 in 70151280.

Going ahead to step 1:
666 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 666

Going ahead to step 2:
When dividing 70 by 666, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 666

Advancing to step 3:
If we divide 701 by 666, we get 1 and a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 666 away from 701, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 666

Step 4:
666 goes into 355 0 times with a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 355 after subtracting 0 from 355.
Fetch the next digit (1) from the dividend, attach it to 355 and continue: 3551 / 666

Going ahead to step 5:
3551 divided by 666 is 5 with a remainder of 221.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Deduct 3330 from 3551 and we're left with 221.
Include the next digit (2) from the dividend after 221, then repeat: 2212 / 666

Going ahead to step 6:
666 can be fit into 2212 3 times, resulting in a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 1053.0
If we take 1998 away from 2212, we end up with 214.
Bring next digit (8) of the dividend behind the 214 and repeat the process: 2148 / 666

Let's proceed to step 7:
666 goes into 2148 3 times with a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 10533.0
Subtract 1998 from 2148 to get 150.
Fetch the next digit (0) from the dividend, attach it to 150 and continue: 1500 / 666

Step 8:
The number 666 fits into 1500 2 times, leaving a remainder of 168.
The next digit of our result is 2. 
Result so far: 105332.0
The remainder is 168 after subtracting 1332 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 9:
The number 666 fits into 1680 2 times, leaving a remainder of 348.
The next digit of our result is 2. 
Result so far: 105332.2
The remainder is 348 after subtracting 1332 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 10:
The number 666 fits into 3480 5 times, leaving a remainder of 150.
The next digit of our result is 5. 
Result so far: 105332.25
Subtracting 3330 from 3480 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
When dividing 1500 by 666, we get 2 with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 105332.252
If we take 1332 away from 1500, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 12:
666 goes into 1680 2 times with a remainder of 348.
Record the quotient 2 as the next digit in the result. 
Result so far: 105332.2522
If we subtract 1332 from 1680, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The final outcome is 105332.2522, with a leftover of 0.00348.
