We look at the division of 92728484 by 390 
The aim is to understand the frequency of 390 in 92728484.

Moving on to step 1:
390 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 390

On to step 2:
390 can be fit into 92 0 times, resulting in a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 92 after subtracting 0 from 92.
Take the next digit (7) from the dividend and append it to 92, then repeat: 927 / 390

Step 3:
When dividing 927 by 390, we get 2 with a remainder of 147.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 780 away from 927, we end up with 147.
Take the next digit (2) from the dividend and append it to 147, then repeat: 1472 / 390

Step 4:
The number 390 fits into 1472 3 times, leaving a remainder of 302.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 1170 from 1472 to get 302.
Fetch the next digit (8) from the dividend, attach it to 302 and continue: 3028 / 390

Let's proceed to step 5:
390 goes into 3028 7 times with a remainder of 298.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
If we take 2730 away from 3028, we end up with 298.
Bring next digit (4) of the dividend behind the 298 and repeat the process: 2984 / 390

Let's proceed to step 6:
The number 390 fits into 2984 7 times, leaving a remainder of 254.
The next digit of our result is 7. 
Result so far: 2377.0
Subtracting 2730 from 2984 leaves us with 254.
Grab the next digit (8) from the dividend, add it to 254, then carry on: 2548 / 390

On to step 7:
If we divide 2548 by 390, we get 6 and a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 23776.0
Deduct 2340 from 2548 and we're left with 208.
Take the next digit (4) from the dividend and append it to 208, then repeat: 2084 / 390

Let's proceed to step 8:
2084 divided by 390 is 5 with a remainder of 134.
The next digit of our result is 5. 
Result so far: 237765.0
The remainder is 134 after subtracting 1950 from 2084.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
If we divide 1340 by 390, we get 3 and a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 237765.3
If we subtract 1170 from 1340, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
390 goes into 1700 4 times with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 237765.34
If we subtract 1560 from 1700, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
390 goes into 1400 3 times with a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 237765.343
Subtract 1170 from 1400 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 12:
390 goes into 2300 5 times with a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 237765.3435
If we subtract 1950 from 2300, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 13:
390 goes into 3500 8 times with a remainder of 380.
Put 8 as the next digit of the answer. 
Result so far: 237765.34358
If we subtract 3120 from 3500, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 14:
3800 divided by 390 is 9 with a remainder of 290.
The next digit of our result is 9. 
Result so far: 237765.343589
If we subtract 3510 from 3800, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 15:
When dividing 2900 by 390, we get 7 with a remainder of 170.
Put 7 as the next digit of the answer. 
Result so far: 237765.3435897
Deduct 2730 from 2900 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 16:
If we divide 1700 by 390, we get 4 and a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 237765.34358974
Subtract 1560 from 1700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 237765.34358974 with a remainder of 1.4e-07.
