Let's divide 74568449 by 39
The aim is to understand the frequency of 39 in 74568449.

Step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 39

Advancing to step 2:
The number 39 fits into 74 1 times, leaving a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 39 away from 74, we end up with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 39

On to step 3:
39 can be fit into 355 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 351 away from 355, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 39

Step 4:
When dividing 46 by 39, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
Deduct 39 from 46 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 39

Going ahead to step 5:
The number 39 fits into 78 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1912.0
If we take 78 away from 78, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 39

Moving on to step 6:
4 divided by 39 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 19120.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 39

Going ahead to step 7:
39 can be fit into 44 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 191201.0
If we take 39 away from 44, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 39

Let's proceed to step 8:
If we divide 59 by 39, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1912011.0
Subtracting 39 from 59 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 39, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1912011.5
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
If we divide 50 by 39, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1912011.51
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
If we divide 110 by 39, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1912011.512
If we subtract 78 from 110, we get 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 12:
39 goes into 320 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 1912011.5128
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
If we divide 80 by 39, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 1912011.51282
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
20 divided by 39 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1912011.51282
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
39 goes into 200 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1912011.5128205
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 16:
When dividing 50 by 39, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1912011.51282051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 1912011.51282051 with a remaining 1.1e-08.
