347916 divided by 39 
The aim is to understand the frequency of 39 in 347916.

Step 1:
The number 39 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 39

On to step 2:
When dividing 34 by 39, we get 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 39

On to step 3:
When dividing 347 by 39, we get 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 312 from 347 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 39

Let's proceed to step 4:
359 divided by 39 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtract 351 from 359 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 39

Going ahead to step 5:
39 can be fit into 81 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 892.0
Subtracting 78 from 81 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 39

On to step 6:
39 can be fit into 36 0 times, resulting in a remainder of 36.
The next digit of our result is 0. 
Result so far: 8920.0
If we take 0 away from 36, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 8920.9
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
90 divided by 39 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 8920.92
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 39 fits into 120 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 8920.923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
If we divide 30 by 39, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 8920.923
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
If we divide 300 by 39, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 8920.92307
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 12:
If we divide 270 by 39, we get 6 and a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 8920.923076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
39 goes into 360 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 8920.9230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
39 goes into 90 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 8920.92307692
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 8920.92307692 and a remainder of 1.2e-08.
