442779 divided by 39 
The aim is to understand the frequency of 39 in 442779.

Moving on to step 1:
39 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 39

Moving on to step 2:
If we divide 44 by 39, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 39 away from 44, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 39

Let's proceed to step 3:
39 can be fit into 52 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 39 away from 52, we end up with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 39

Moving on to step 4:
The number 39 fits into 137 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 113.0
If we subtract 117 from 137, we get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 39

Going ahead to step 5:
39 goes into 207 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 1135.0
Subtract 195 from 207 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 39

On to step 6:
39 can be fit into 129 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 11353.0
If we subtract 117 from 129, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
When dividing 120 by 39, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 11353.3
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
30 divided by 39 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11353.3
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 39, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 11353.307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 11353.3076
The remainder is 36 after subtracting 234 from 270.
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:
39 goes into 360 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 11353.30769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
39 goes into 90 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 11353.307692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
39 goes into 120 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 11353.3076923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
When dividing 30 by 39, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11353.3076923
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 11353.3076923 and a remainder of 3e-08.
