We look at the division of 64805841 by 672 
The aim is to understand the frequency of 672 in 64805841.

Let's proceed to step 1:
The number 672 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 672

Step 2:
If we divide 64 by 672, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 672

Moving on to step 3:
648 divided by 672 is 0 with a remainder of 648.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 648, we get 648.
Append the next digit (0) from the dividend to 648 and continue with: 6480 / 672

On to step 4:
6480 divided by 672 is 9 with a remainder of 432.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 6048 from 6480 to get 432.
Include the next digit (5) from the dividend after 432, then repeat: 4325 / 672

Step 5:
If we divide 4325 by 672, we get 6 and a remainder of 293.
The next digit of our result is 6. 
Result so far: 96.0
Subtracting 4032 from 4325 leaves us with 293.
Include the next digit (8) from the dividend after 293, then repeat: 2938 / 672

Moving on to step 6:
672 can be fit into 2938 4 times, resulting in a remainder of 250.
The next digit of our result is 4. 
Result so far: 964.0
If we subtract 2688 from 2938, we get 250.
Take the next digit (4) from the dividend and append it to 250, then repeat: 2504 / 672

Moving on to step 7:
672 goes into 2504 3 times with a remainder of 488.
Write down 3 as next digit of the result. 
Result so far: 9643.0
Subtracting 2016 from 2504 leaves us with 488.
Bring next digit (1) of the dividend behind the 488 and repeat the process: 4881 / 672

Moving on to step 8:
672 goes into 4881 7 times with a remainder of 177.
The number 7 becomes the next digit in our result. 
Result so far: 96437.0
The remainder is 177 after subtracting 4704 from 4881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 9:
1770 divided by 672 is 2 with a remainder of 426.
Record the quotient 2 as the next digit in the result. 
Result so far: 96437.2
Subtract 1344 from 1770 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 10:
672 can be fit into 4260 6 times, resulting in a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 96437.26
If we subtract 4032 from 4260, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 11:
672 can be fit into 2280 3 times, resulting in a remainder of 264.
Write down 3 as next digit of the result. 
Result so far: 96437.263
Subtract 2016 from 2280 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 12:
2640 divided by 672 is 3 with a remainder of 624.
The number 3 becomes the next digit in our result. 
Result so far: 96437.2633
If we take 2016 away from 2640, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Our division results in 96437.2633 with a remaining 0.00624.
