637348 ÷ 39 
The aim is to understand the frequency of 39 in 637348.

Step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 39

Going ahead to step 2:
When dividing 63 by 39, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 39 from 63, we get 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 39

Let's proceed to step 3:
247 divided by 39 is 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 234 from 247 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 39

Step 4:
If we divide 133 by 39, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Subtracting 117 from 133 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 39

On to step 5:
164 divided by 39 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1634.0
The remainder is 8 after subtracting 156 from 164.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 39

Moving on to step 6:
39 goes into 88 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 16342.0
Subtracting 78 from 88 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 39 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 16342.2
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 16342.25
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
When dividing 250 by 39, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 16342.256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 16342.2564
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 39 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 16342.25641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
The number 39 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 16342.25641
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 39, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 16342.2564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
220 divided by 39 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 16342.25641025
Subtract 195 from 220 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 16342.25641025 with a balance of 2.5e-08.
