We divide 529975 by 669
The aim is to understand the frequency of 669 in 529975.

Going ahead to step 1:
669 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 669

Step 2:
52 divided by 669 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 669

On to step 3:
If we divide 529 by 669, we get 0 and a remainder of 529.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 529 and we're left with 529.
Grab the next digit (9) from the dividend, add it to 529, then carry on: 5299 / 669

Step 4:
When dividing 5299 by 669, we get 7 with a remainder of 616.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4683 from 5299 to get 616.
Take the next digit (7) from the dividend and append it to 616, then repeat: 6167 / 669

Let's proceed to step 5:
669 goes into 6167 9 times with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 6021 away from 6167, we end up with 146.
Bring next digit (5) of the dividend behind the 146 and repeat the process: 1465 / 669

On to step 6:
The number 669 fits into 1465 2 times, leaving a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 792.0
If we subtract 1338 from 1465, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 7:
669 goes into 1270 1 times with a remainder of 601.
Use 1 as the next digit of our solution. 
Result so far: 792.1
Subtract 669 from 1270 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Let's proceed to step 8:
669 can be fit into 6010 8 times, resulting in a remainder of 658.
Record the quotient 8 as the next digit in the result. 
Result so far: 792.18
Deduct 5352 from 6010 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 9:
669 goes into 6580 9 times with a remainder of 559.
The next digit of our result is 9. 
Result so far: 792.189
If we subtract 6021 from 6580, we get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

On to step 10:
669 goes into 5590 8 times with a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 792.1898
Subtracting 5352 from 5590 leaves us 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.

Going ahead to step 11:
669 can be fit into 2380 3 times, resulting in a remainder of 373.
Use 3 as the next digit of our solution. 
Result so far: 792.18983
Subtract 2007 from 2380 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 12:
When dividing 3730 by 669, we get 5 with a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 792.189835
Subtract 3345 from 3730 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 13:
669 can be fit into 3850 5 times, resulting in a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 792.1898355
Deduct 3345 from 3850 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The quotient of the division is 792.1898355, and the remainder is 5.05e-06.
