We look at the division of 577641 by 74 
The aim is to understand the frequency of 74 in 577641.

Step 1:
74 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 74

Step 2:
74 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 74

On to step 3:
The number 74 fits into 577 7 times, leaving a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 518 from 577 leaves us with 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 74

Advancing to step 4:
When dividing 596 by 74, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 592 away from 596, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 74

Advancing to step 5:
44 divided by 74 is 0 with a remainder of 44.
The next digit of our result is 0. 
Result so far: 780.0
Subtracting 0 from 44 leaves us with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 74

Step 6:
441 divided by 74 is 5 with a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 7805.0
Subtracting 370 from 441 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
The number 74 fits into 710 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 7805.9
Subtract 666 from 710 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
440 divided by 74 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 7805.95
Subtracting 370 from 440 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
700 divided by 74 is 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 7805.959
If we subtract 666 from 700, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
74 goes into 340 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 7805.9594
Subtracting 296 from 340 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
74 can be fit into 440 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 7805.95945
Subtract 370 from 440 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 12:
74 goes into 700 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 7805.959459
Subtracting 666 from 700 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
74 can be fit into 340 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 7805.9594594
The remainder is 44 after subtracting 296 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
440 divided by 74 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 7805.95945945
Deduct 370 from 440 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 7805.95945945 with a remaining 7e-08.
