We're dividing 64818117 by 669 
The aim is to understand the frequency of 669 in 64818117.

Advancing to step 1:
669 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 669

Step 2:
The number 669 fits into 64 0 times, leaving a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 669

Moving on to step 3:
669 goes into 648 0 times with a remainder of 648.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 648 and we're left with 648.
Include the next digit (1) from the dividend after 648, then repeat: 6481 / 669

On to step 4:
If we divide 6481 by 669, we get 9 and a remainder of 460.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 460 after subtracting 6021 from 6481.
Fetch the next digit (8) from the dividend, attach it to 460 and continue: 4608 / 669

Going ahead to step 5:
4608 divided by 669 is 6 with a remainder of 594.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 4014 from 4608 and we're left with 594.
Include the next digit (1) from the dividend after 594, then repeat: 5941 / 669

Let's proceed to step 6:
669 can be fit into 5941 8 times, resulting in a remainder of 589.
The next digit of our result is 8. 
Result so far: 968.0
The remainder is 589 after subtracting 5352 from 5941.
Fetch the next digit (1) from the dividend, attach it to 589 and continue: 5891 / 669

Let's proceed to step 7:
When dividing 5891 by 669, we get 8 with a remainder of 539.
Write down 8 as next digit of the result. 
Result so far: 9688.0
Deduct 5352 from 5891 and we're left with 539.
Include the next digit (7) from the dividend after 539, then repeat: 5397 / 669

Going ahead to step 8:
669 can be fit into 5397 8 times, resulting in a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 96888.0
Subtract 5352 from 5397 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 9:
The number 669 fits into 450 0 times, leaving a remainder of 450.
The next digit of our result is 0. 
Result so far: 96888.0
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 10:
669 goes into 4500 6 times with a remainder of 486.
Write down 6 as next digit of the result. 
Result so far: 96888.06
Deduct 4014 from 4500 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 11:
When dividing 4860 by 669, we get 7 with a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 96888.067
If we subtract 4683 from 4860, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 12:
669 can be fit into 1770 2 times, resulting in a remainder of 432.
Record the quotient 2 as the next digit in the result. 
Result so far: 96888.0672
The remainder is 432 after subtracting 1338 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 13:
669 goes into 4320 6 times with a remainder of 306.
Use 6 as the next digit of our solution. 
Result so far: 96888.06726
If we subtract 4014 from 4320, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 14:
3060 divided by 669 is 4 with a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 96888.067264
Deduct 2676 from 3060 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 15:
669 can be fit into 3840 5 times, resulting in a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 96888.0672645
Deduct 3345 from 3840 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 16:
669 goes into 4950 7 times with a remainder of 267.
Put 7 as the next digit of the answer. 
Result so far: 96888.06726457
Deduct 4683 from 4950 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

The final result is 96888.06726457 with a remainder of 2.67e-07.
