We look at the division of 65558645 by 74 
The aim is to understand the frequency of 74 in 65558645.

On to step 1:
When dividing 6 by 74, we get 0 with 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.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 74

Step 2:
If we divide 65 by 74, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Append the next digit (5) from the dividend to 65 and continue with: 655 / 74

Let's proceed to step 3:
74 can be fit into 655 8 times, resulting in a remainder of 63.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 592 away from 655, we end up with 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 74

Advancing to step 4:
74 can be fit into 635 8 times, resulting in a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtracting 592 from 635 leaves us with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 74

Moving on to step 5:
74 can be fit into 438 5 times, resulting in a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 885.0
Subtracting 370 from 438 leaves us with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 74

Moving on to step 6:
74 can be fit into 686 9 times, resulting in a remainder of 20.
The next digit of our result is 9. 
Result so far: 8859.0
Subtract 666 from 686 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 74

On to step 7:
74 goes into 204 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 88592.0
The remainder is 56 after subtracting 148 from 204.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 74

Step 8:
If we divide 565 by 74, we get 7 and a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 885927.0
Subtracting 518 from 565 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 9:
When dividing 470 by 74, we get 6 with a remainder of 26.
The next digit of our result is 6. 
Result so far: 885927.6
If we subtract 444 from 470, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 885927.63
Subtracting 222 from 260 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
380 divided by 74 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 885927.635
Subtract 370 from 380 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
If we divide 100 by 74, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 885927.6351
The remainder is 26 after subtracting 74 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 885927.63513
If we subtract 222 from 260, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
If we divide 380 by 74, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 885927.635135
Deduct 370 from 380 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 15:
74 can be fit into 100 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 885927.6351351
If we take 74 away from 100, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 16:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 885927.63513513
If we subtract 222 from 260, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 885927.63513513 with a remaining 3.8e-08.
