We're dividing 64574488 by 647 
The aim is to understand the frequency of 647 in 64574488.

Advancing to step 1:
If we divide 6 by 647, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 647

Let's proceed to step 2:
If we divide 64 by 647, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 647

On to step 3:
The number 647 fits into 645 0 times, leaving a remainder of 645.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 645 leaves us with 645.
Take the next digit (7) from the dividend and append it to 645, then repeat: 6457 / 647

Advancing to step 4:
647 can be fit into 6457 9 times, resulting in a remainder of 634.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 5823 from 6457 leaves us with 634.
Fetch the next digit (4) from the dividend, attach it to 634 and continue: 6344 / 647

Step 5:
647 goes into 6344 9 times with a remainder of 521.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we subtract 5823 from 6344, we get 521.
Fetch the next digit (4) from the dividend, attach it to 521 and continue: 5214 / 647

Advancing to step 6:
If we divide 5214 by 647, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 998.0
Deduct 5176 from 5214 and we're left with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 647

On to step 7:
The number 647 fits into 388 0 times, leaving a remainder of 388.
Put 0 as the next digit of the answer. 
Result so far: 9980.0
If we subtract 0 from 388, we get 388.
Include the next digit (8) from the dividend after 388, then repeat: 3888 / 647

Advancing to step 8:
The number 647 fits into 3888 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 99806.0
Subtract 3882 from 3888 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
647 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 99806.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 647 fits into 600 0 times, leaving a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 99806.0
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 99806.0, and the remainder is 0.6.
