We look at the division of 605642 by 39 
The aim is to understand the frequency of 39 in 605642.

Going ahead to step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 39

Going ahead to step 2:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 60 to get 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 39

Moving on to step 3:
215 divided by 39 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 195 away from 215, we end up with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 39

Step 4:
39 can be fit into 206 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
If we take 195 away from 206, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 39

Let's proceed to step 5:
When dividing 114 by 39, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1552.0
Deduct 78 from 114 and we're left with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 39

Advancing to step 6:
39 can be fit into 362 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 15529.0
If we take 351 away from 362, we end up 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.

Let's proceed to step 7:
110 divided by 39 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 15529.2
If we take 78 away from 110, we end up with 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 8:
39 goes into 320 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 15529.28
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 9:
80 divided by 39 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 15529.282
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 39 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 15529.282
Subtracting 0 from 20 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.

Step 11:
The number 39 fits into 200 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 15529.28205
Subtract 195 from 200 to 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.

Advancing to step 12:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 15529.282051
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.

Moving on to step 13:
If we divide 110 by 39, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 15529.2820512
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
If we divide 320 by 39, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 15529.28205128
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.

After the division, we end up with 15529.28205128 and a remainder of 8e-09.
