We divide 83312725 by 669
The aim is to understand the frequency of 669 in 83312725.

Step 1:
669 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 669

Going ahead to step 2:
669 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Fetch the next digit (3) from the dividend, attach it to 83 and continue: 833 / 669

Going ahead to step 3:
When dividing 833 by 669, we get 1 with a remainder of 164.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 164 after subtracting 669 from 833.
Bring next digit (1) of the dividend behind the 164 and repeat the process: 1641 / 669

Going ahead to step 4:
669 goes into 1641 2 times with a remainder of 303.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1338 from 1641, we get 303.
Fetch the next digit (2) from the dividend, attach it to 303 and continue: 3032 / 669

Moving on to step 5:
If we divide 3032 by 669, we get 4 and a remainder of 356.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 2676 from 3032 leaves us with 356.
Include the next digit (7) from the dividend after 356, then repeat: 3567 / 669

Going ahead to step 6:
If we divide 3567 by 669, we get 5 and a remainder of 222.
Record the quotient 5 as the next digit in the result. 
Result so far: 1245.0
The remainder is 222 after subtracting 3345 from 3567.
Take the next digit (2) from the dividend and append it to 222, then repeat: 2222 / 669

Step 7:
When dividing 2222 by 669, we get 3 with a remainder of 215.
The next digit of our result is 3. 
Result so far: 12453.0
Subtracting 2007 from 2222 leaves us with 215.
Take the next digit (5) from the dividend and append it to 215, then repeat: 2155 / 669

Step 8:
669 can be fit into 2155 3 times, resulting in a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 124533.0
Subtracting 2007 from 2155 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 9:
669 goes into 1480 2 times with a remainder of 142.
Write down 2 as next digit of the result. 
Result so far: 124533.2
If we subtract 1338 from 1480, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Going ahead to step 10:
669 goes into 1420 2 times with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 124533.22
Subtract 1338 from 1420 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 124533.22 with a remaining 0.082.
