We're dividing 70484416 by 390 
The aim is to understand the frequency of 390 in 70484416.

Let's proceed to step 1:
7 divided by 390 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 390

Going ahead to step 2:
If we divide 70 by 390, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 390

Let's proceed to step 3:
When dividing 704 by 390, we get 1 with a remainder of 314.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 390 from 704 and we're left with 314.
Include the next digit (8) from the dividend after 314, then repeat: 3148 / 390

Advancing to step 4:
390 goes into 3148 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 3120 from 3148 to get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 390

Let's proceed to step 5:
The number 390 fits into 284 0 times, leaving a remainder of 284.
Put 0 as the next digit of the answer. 
Result so far: 180.0
If we subtract 0 from 284, we get 284.
Include the next digit (4) from the dividend after 284, then repeat: 2844 / 390

Let's proceed to step 6:
The number 390 fits into 2844 7 times, leaving a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 1807.0
If we take 2730 away from 2844, we end up with 114.
Grab the next digit (1) from the dividend, add it to 114, then carry on: 1141 / 390

Let's proceed to step 7:
390 can be fit into 1141 2 times, resulting in a remainder of 361.
The next digit of our result is 2. 
Result so far: 18072.0
Deduct 780 from 1141 and we're left with 361.
Append the next digit (6) from the dividend to 361 and continue with: 3616 / 390

Moving on to step 8:
If we divide 3616 by 390, we get 9 and a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 180729.0
If we take 3510 away from 3616, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 9:
390 can be fit into 1060 2 times, resulting in a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 180729.2
The remainder is 280 after subtracting 780 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
The number 390 fits into 2800 7 times, leaving a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 180729.27
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.

Step 11:
If we divide 700 by 390, we get 1 and a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 180729.271
If we take 390 away from 700, we end up 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.

Step 12:
390 goes into 3100 7 times with a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 180729.2717
Subtract 2730 from 3100 to 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.

Let's proceed to step 13:
If we divide 3700 by 390, we get 9 and a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 180729.27179
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.

Going ahead to step 14:
If we divide 1900 by 390, we get 4 and a remainder of 340.
Put 4 as the next digit of the answer. 
Result so far: 180729.271794
Subtract 1560 from 1900 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
When dividing 3400 by 390, we get 8 with a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 180729.2717948
Subtracting 3120 from 3400 leaves us 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.

Moving on to step 16:
390 can be fit into 2800 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 180729.27179487
The remainder is 70 after subtracting 2730 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 180729.27179487 with a remainder of 7e-08.
