We look at the division of 42593391 by 74 
The aim is to understand the frequency of 74 in 42593391.

Step 1:
If we divide 4 by 74, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 74

Moving on to step 2:
74 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 74

Step 3:
If we divide 425 by 74, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 370 from 425 and we're left with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 74

Let's proceed to step 4:
74 goes into 559 7 times with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 518 away from 559, we end up with 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 74

On to step 5:
The number 74 fits into 413 5 times, leaving a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
If we subtract 370 from 413, we get 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 74

Moving on to step 6:
74 goes into 433 5 times with a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 5755.0
Subtract 370 from 433 to get 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 74

Moving on to step 7:
74 goes into 639 8 times with a remainder of 47.
The next digit of our result is 8. 
Result so far: 57558.0
Subtract 592 from 639 to get 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 74

Step 8:
471 divided by 74 is 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 575586.0
The remainder is 27 after subtracting 444 from 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
74 goes into 270 3 times with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 575586.3
If we take 222 away from 270, 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.

Advancing to step 10:
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: 575586.36
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.

On to step 11:
74 goes into 360 4 times with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 575586.364
Subtracting 296 from 360 leaves us 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.

On to step 12:
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: 575586.3648
Deduct 592 from 640 and we're left 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.

Advancing to step 13:
The number 74 fits into 480 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 575586.36486
If we subtract 444 from 480, we 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.

On to step 14:
360 divided by 74 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 575586.364864
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.

Step 15:
When dividing 640 by 74, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 575586.3648648
Deduct 592 from 640 and we're left 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.

Advancing to step 16:
The number 74 fits into 480 6 times, leaving a remainder of 36.
The next digit of our result is 6. 
Result so far: 575586.36486486
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.

Our division results in 575586.36486486 with a remaining 3.6e-08.
