16417751 divided by 669 
The aim is to understand the frequency of 669 in 16417751.

Going ahead to step 1:
The number 669 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 669

Step 2:
The number 669 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 669

On to step 3:
If we divide 164 by 669, we get 0 and a remainder of 164.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 164 and we're left with 164.
Bring next digit (1) of the dividend behind the 164 and repeat the process: 1641 / 669

Moving on to step 4:
1641 divided by 669 is 2 with a remainder of 303.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1338 from 1641 leaves us with 303.
Bring next digit (7) of the dividend behind the 303 and repeat the process: 3037 / 669

On to step 5:
When dividing 3037 by 669, we get 4 with a remainder of 361.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 2676 from 3037 to get 361.
Append the next digit (7) from the dividend to 361 and continue with: 3617 / 669

Going ahead to step 6:
The number 669 fits into 3617 5 times, leaving a remainder of 272.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
Deduct 3345 from 3617 and we're left with 272.
Append the next digit (5) from the dividend to 272 and continue with: 2725 / 669

Advancing to step 7:
When dividing 2725 by 669, we get 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 2454.0
Deduct 2676 from 2725 and we're left with 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 669

On to step 8:
669 goes into 491 0 times with a remainder of 491.
Record the quotient 0 as the next digit in the result. 
Result so far: 24540.0
The remainder is 491 after subtracting 0 from 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Going ahead to step 9:
If we divide 4910 by 669, we get 7 and a remainder of 227.
Use 7 as the next digit of our solution. 
Result so far: 24540.7
The remainder is 227 after subtracting 4683 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Moving on to step 10:
669 can be fit into 2270 3 times, resulting in a remainder of 263.
Put 3 as the next digit of the answer. 
Result so far: 24540.73
Subtracting 2007 from 2270 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 11:
If we divide 2630 by 669, we get 3 and a remainder of 623.
The next digit of our result is 3. 
Result so far: 24540.733
If we take 2007 away from 2630, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

The final result is 24540.733 with a remainder of 0.0623.
