We look at the division of 79926464 by 390 
The aim is to understand the frequency of 390 in 79926464.

On to step 1:
390 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 390

On to step 2:
When dividing 79 by 390, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 390

Advancing to step 3:
If we divide 799 by 390, we get 2 and a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 780 from 799 leaves us with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 390

Let's proceed to step 4:
390 goes into 192 0 times with a remainder of 192.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 192 leaves us with 192.
Fetch the next digit (6) from the dividend, attach it to 192 and continue: 1926 / 390

Let's proceed to step 5:
1926 divided by 390 is 4 with a remainder of 366.
Write down 4 as next digit of the result. 
Result so far: 204.0
If we subtract 1560 from 1926, we get 366.
Include the next digit (4) from the dividend after 366, then repeat: 3664 / 390

Let's proceed to step 6:
390 can be fit into 3664 9 times, resulting in a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 2049.0
If we take 3510 away from 3664, we end up with 154.
Bring next digit (6) of the dividend behind the 154 and repeat the process: 1546 / 390

Let's proceed to step 7:
390 can be fit into 1546 3 times, resulting in a remainder of 376.
The number 3 becomes the next digit in our result. 
Result so far: 20493.0
Subtracting 1170 from 1546 leaves us with 376.
Bring next digit (4) of the dividend behind the 376 and repeat the process: 3764 / 390

Moving on to step 8:
When dividing 3764 by 390, we get 9 with a remainder of 254.
The next digit of our result is 9. 
Result so far: 204939.0
If we subtract 3510 from 3764, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 9:
When dividing 2540 by 390, we get 6 with a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 204939.6
The remainder is 200 after subtracting 2340 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
If we divide 2000 by 390, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 204939.65
Subtracting 1950 from 2000 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
390 goes into 500 1 times with a remainder of 110.
The next digit of our result is 1. 
Result so far: 204939.651
Deduct 390 from 500 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
390 can be fit into 1100 2 times, resulting in a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 204939.6512
Subtract 780 from 1100 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
3200 divided by 390 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 204939.65128
If we subtract 3120 from 3200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
If we divide 800 by 390, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 204939.651282
Subtract 780 from 800 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
If we divide 200 by 390, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 204939.651282
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 16:
When dividing 2000 by 390, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 204939.65128205
The remainder is 50 after subtracting 1950 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 204939.65128205 with a balance of 5e-08.
