664584 ÷ 74 
The aim is to understand the frequency of 74 in 664584.

Let's proceed to step 1:
74 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 74

Moving on to step 2:
The number 74 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 74

Advancing to step 3:
The number 74 fits into 664 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 592 from 664 and we're left with 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 74

Going ahead to step 4:
74 can be fit into 725 9 times, resulting in a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Deduct 666 from 725 and we're left with 59.
Fetch the next digit (8) from the dividend, attach it to 59 and continue: 598 / 74

Let's proceed to step 5:
74 goes into 598 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 898.0
Subtracting 592 from 598 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 74

Going ahead to step 6:
74 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 8980.0
Subtract 0 from 64 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
If we divide 640 by 74, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8980.8
The remainder is 48 after subtracting 592 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
If we divide 480 by 74, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 8980.86
Subtract 444 from 480 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
74 can be fit into 360 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 8980.864
If we take 296 away from 360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
If we divide 640 by 74, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 8980.8648
If we take 592 away from 640, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
The number 74 fits into 480 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 8980.86486
Subtracting 444 from 480 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
When dividing 360 by 74, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 8980.864864
Subtract 296 from 360 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
When dividing 640 by 74, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8980.8648648
The remainder is 48 after subtracting 592 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
If we divide 480 by 74, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 8980.86486486
Subtract 444 from 480 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 8980.86486486, with a leftover of 3.6e-08.
