457283 ÷ 39 
The aim is to understand the frequency of 39 in 457283.

On to step 1:
4 divided by 39 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 39

Moving on to step 2:
39 can be fit into 45 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 39 from 45.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 39

Let's proceed to step 3:
The number 39 fits into 67 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 39 away from 67, we end up with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 39

Moving on to step 4:
39 goes into 282 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 117.0
If we subtract 273 from 282, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 39

Moving on to step 5:
98 divided by 39 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
Subtracting 78 from 98 leaves us with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 39

Step 6:
203 divided by 39 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 11725.0
Subtracting 195 from 203 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.

Moving on to step 7:
80 divided by 39 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 11725.2
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
39 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 11725.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 39, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11725.205
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
50 divided by 39 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11725.2051
The remainder is 11 after subtracting 39 from 50.
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 11:
39 can be fit into 110 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 11725.20512
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.

On to step 12:
39 can be fit into 320 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11725.205128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
39 can be fit into 80 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 11725.2051282
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.

On to step 14:
39 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11725.2051282
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 11725.2051282, with a leftover of 2e-08.
