100446 divided by 39 
The aim is to understand the frequency of 39 in 100446.

On to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 39

Advancing to step 2:
If we divide 10 by 39, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 39

Going ahead to step 3:
39 can be fit into 100 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 22 after subtracting 78 from 100.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 39

Let's proceed to step 4:
39 can be fit into 224 5 times, resulting in a remainder of 29.
The next digit of our result is 5. 
Result so far: 25.0
The remainder is 29 after subtracting 195 from 224.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 39

Going ahead to step 5:
39 goes into 294 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 257.0
Subtract 273 from 294 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 39

Going ahead to step 6:
When dividing 216 by 39, we get 5 with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 2575.0
Subtracting 195 from 216 leaves us 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 7:
210 divided by 39 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2575.5
Subtracting 195 from 210 leaves us 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.

On to step 8:
150 divided by 39 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 2575.53
Subtracting 117 from 150 leaves us 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.

Let's proceed to step 9:
330 divided by 39 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 2575.538
If we subtract 312 from 330, we 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 10:
180 divided by 39 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 2575.5384
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.

Advancing to step 11:
39 goes into 240 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2575.53846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
39 goes into 60 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 2575.538461
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 13:
The number 39 fits into 210 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2575.5384615
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.

Let's proceed to step 14:
If we divide 150 by 39, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 2575.53846153
Subtract 117 from 150 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 2575.53846153, with a leftover of 3.3e-08.
