We look at the division of 945777 by 39 
The aim is to understand the frequency of 39 in 945777.

Moving on to step 1:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 39

Advancing to step 2:
39 can be fit into 94 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
If we take 78 away from 94, we end up with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 39

Advancing to step 3:
39 goes into 165 4 times with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 156 from 165, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 39

Going ahead to step 4:
97 divided by 39 is 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 242.0
Deduct 78 from 97 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 39

On to step 5:
The number 39 fits into 197 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 2425.0
If we subtract 195 from 197, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 39

Let's proceed to step 6:
39 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 24250.0
Subtracting 0 from 27 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
39 goes into 270 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 24250.6
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 24250.69
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 24250.692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 39 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 24250.6923
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.

Let's proceed to step 11:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 24250.6923
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
39 goes into 300 7 times with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 24250.692307
The remainder is 27 after subtracting 273 from 300.
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 13:
39 goes into 270 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 24250.6923076
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
360 divided by 39 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 24250.69230769
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 24250.69230769 with a remainder of 9e-09.
