We look at the division of 660445 by 74 
The aim is to understand the frequency of 74 in 660445.

Let's proceed to step 1:
74 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 74

Step 2:
74 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 74

Moving on to step 3:
74 goes into 660 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 592 from 660 and we're left with 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 74

Going ahead to step 4:
684 divided by 74 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 666 from 684, we get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 74

Advancing to step 5:
184 divided by 74 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 892.0
The remainder is 36 after subtracting 148 from 184.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 74

Advancing to step 6:
The number 74 fits into 365 4 times, leaving a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 8924.0
Subtract 296 from 365 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 7:
74 goes into 690 9 times with a remainder of 24.
The next digit of our result is 9. 
Result so far: 8924.9
Subtracting 666 from 690 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
If we divide 240 by 74, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 8924.93
If we take 222 away from 240, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 74 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 8924.932
Subtracting 148 from 180 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
320 divided by 74 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8924.9324
The remainder is 24 after subtracting 296 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
The number 74 fits into 240 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 8924.93243
The remainder is 18 after subtracting 222 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 74, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8924.932432
Subtracting 148 from 180 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
74 can be fit into 320 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 8924.9324324
If we take 296 away from 320, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
When dividing 240 by 74, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 8924.93243243
If we subtract 222 from 240, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 8924.93243243 with a remaining 1.8e-08.
