478185 divided by 39 
The aim is to understand the frequency of 39 in 478185.

Going ahead to step 1:
4 divided by 39 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 39

Going ahead to step 2:
If we divide 47 by 39, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 47 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 39

Step 3:
88 divided by 39 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 10 after subtracting 78 from 88.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 39

Step 4:
The number 39 fits into 101 2 times, leaving a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 23 after subtracting 78 from 101.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 39

Advancing to step 5:
The number 39 fits into 238 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1226.0
Subtracting 234 from 238 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 39

Moving on to step 6:
The number 39 fits into 45 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 12261.0
The remainder is 6 after subtracting 39 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 39, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 12261.1
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
If we divide 210 by 39, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12261.15
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 12261.153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
If we divide 330 by 39, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 12261.1538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
When dividing 180 by 39, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 12261.15384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 12261.153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
When dividing 60 by 39, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 12261.1538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
If we divide 210 by 39, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 12261.15384615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 12261.15384615, and the remainder is 1.5e-08.
