We're dividing 31315309 by 74 
The aim is to understand the frequency of 74 in 31315309.

Going ahead to step 1:
When dividing 3 by 74, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 74

Going ahead to step 2:
74 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 74

On to step 3:
When dividing 313 by 74, we get 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 296 from 313 and we're left with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 74

Moving on to step 4:
If we divide 171 by 74, we get 2 and a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 148 from 171 to get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 74

Let's proceed to step 5:
The number 74 fits into 235 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 423.0
If we subtract 222 from 235, we get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 74

Let's proceed to step 6:
The number 74 fits into 133 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 4231.0
If we take 74 away from 133, we end up with 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 74

Let's proceed to step 7:
74 goes into 590 7 times with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 42317.0
If we take 518 away from 590, we end up with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 74

Moving on to step 8:
When dividing 729 by 74, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 423179.0
If we subtract 666 from 729, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
The number 74 fits into 630 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 423179.8
If we subtract 592 from 630, 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.

Moving on to step 10:
74 goes into 380 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 423179.85
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.

Let's proceed to step 11:
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: 423179.851
Deduct 74 from 100 and we're left 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.

Step 12:
The number 74 fits into 260 3 times, leaving a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 423179.8513
Subtract 222 from 260 to 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.

Going ahead to step 13:
380 divided by 74 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 423179.85135
If we subtract 370 from 380, we 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.

Moving on to step 14:
When dividing 100 by 74, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 423179.851351
Subtract 74 from 100 to 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.

Going ahead to step 15:
260 divided by 74 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 423179.8513513
The remainder is 38 after subtracting 222 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 16:
When dividing 380 by 74, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 423179.85135135
Subtracting 370 from 380 leaves us 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.

Our division results in 423179.85135135 with a remaining 1e-08.
