39744733 divided by 390 
The aim is to understand the frequency of 390 in 39744733.

Moving on to step 1:
3 divided by 390 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 390

Moving on to step 2:
390 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 390

Let's proceed to step 3:
390 can be fit into 397 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 390 from 397, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 390

On to step 4:
If we divide 74 by 390, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 74, we end up with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 390

Moving on to step 5:
390 goes into 744 1 times with a remainder of 354.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Subtract 390 from 744 to get 354.
Include the next digit (7) from the dividend after 354, then repeat: 3547 / 390

Moving on to step 6:
390 goes into 3547 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 1019.0
The remainder is 37 after subtracting 3510 from 3547.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 390

Moving on to step 7:
If we divide 373 by 390, we get 0 and a remainder of 373.
Record the quotient 0 as the next digit in the result. 
Result so far: 10190.0
Subtract 0 from 373 to get 373.
Grab the next digit (3) from the dividend, add it to 373, then carry on: 3733 / 390

Going ahead to step 8:
390 can be fit into 3733 9 times, resulting in a remainder of 223.
Record the quotient 9 as the next digit in the result. 
Result so far: 101909.0
If we subtract 3510 from 3733, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
390 can be fit into 2230 5 times, resulting in a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 101909.5
Deduct 1950 from 2230 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
2800 divided by 390 is 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 101909.57
If we subtract 2730 from 2800, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
If we divide 700 by 390, we get 1 and a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 101909.571
Deduct 390 from 700 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 12:
3100 divided by 390 is 7 with a remainder of 370.
The next digit of our result is 7. 
Result so far: 101909.5717
If we subtract 2730 from 3100, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 13:
If we divide 3700 by 390, we get 9 and a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 101909.57179
If we subtract 3510 from 3700, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 14:
390 can be fit into 1900 4 times, resulting in a remainder of 340.
The next digit of our result is 4. 
Result so far: 101909.571794
If we take 1560 away from 1900, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
390 goes into 3400 8 times with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 101909.5717948
If we subtract 3120 from 3400, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 16:
390 can be fit into 2800 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 101909.57179487
Subtracting 2730 from 2800 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 101909.57179487 with a balance of 7e-08.
