488887 ÷ 39 
The aim is to understand the frequency of 39 in 488887.

Going ahead to step 1:
If we divide 4 by 39, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 39

Going ahead to step 2:
If we divide 48 by 39, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 39 away from 48, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 39

On to step 3:
The number 39 fits into 98 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 78 from 98 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 39

Let's proceed to step 4:
The number 39 fits into 208 5 times, leaving a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
If we take 195 away from 208, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 39

Moving on to step 5:
If we divide 138 by 39, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1253.0
Subtracting 117 from 138 leaves us with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 39

Going ahead to step 6:
39 goes into 217 5 times with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 12535.0
Subtracting 195 from 217 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
220 divided by 39 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12535.5
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.

Step 8:
The number 39 fits into 250 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 12535.56
Deduct 234 from 250 and we're left 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.

Moving on to step 9:
160 divided by 39 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 12535.564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 39 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 12535.5641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
When dividing 10 by 39, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12535.5641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 39, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 12535.564102
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.

On to step 13:
39 goes into 220 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12535.5641025
Subtracting 195 from 220 leaves us 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.

Step 14:
If we divide 250 by 39, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 12535.56410256
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 12535.56410256 with a balance of 1.6e-08.
