We look at the division of 78030319 by 739 
The aim is to understand the frequency of 739 in 78030319.

Step 1:
739 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 739

On to step 2:
739 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 739

Going ahead to step 3:
780 divided by 739 is 1 with a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 41 after subtracting 739 from 780.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 739

On to step 4:
When dividing 413 by 739, we get 0 with a remainder of 413.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 413, we get 413.
Take the next digit (0) from the dividend and append it to 413, then repeat: 4130 / 739

Step 5:
The number 739 fits into 4130 5 times, leaving a remainder of 435.
The next digit of our result is 5. 
Result so far: 105.0
Subtracting 3695 from 4130 leaves us with 435.
Grab the next digit (3) from the dividend, add it to 435, then carry on: 4353 / 739

Step 6:
The number 739 fits into 4353 5 times, leaving a remainder of 658.
Write down 5 as next digit of the result. 
Result so far: 1055.0
Subtract 3695 from 4353 to get 658.
Include the next digit (1) from the dividend after 658, then repeat: 6581 / 739

Let's proceed to step 7:
If we divide 6581 by 739, we get 8 and a remainder of 669.
Use 8 as the next digit of our solution. 
Result so far: 10558.0
If we take 5912 away from 6581, we end up with 669.
Include the next digit (9) from the dividend after 669, then repeat: 6699 / 739

Going ahead to step 8:
739 can be fit into 6699 9 times, resulting in a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 105589.0
The remainder is 48 after subtracting 6651 from 6699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
If we divide 480 by 739, we get 0 and a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 105589.0
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
If we divide 4800 by 739, we get 6 and a remainder of 366.
The next digit of our result is 6. 
Result so far: 105589.06
If we subtract 4434 from 4800, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 11:
739 goes into 3660 4 times with a remainder of 704.
Write down 4 as next digit of the result. 
Result so far: 105589.064
Subtracting 2956 from 3660 leaves us with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

On to step 12:
7040 divided by 739 is 9 with a remainder of 389.
The next digit of our result is 9. 
Result so far: 105589.0649
Subtract 6651 from 7040 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 13:
739 can be fit into 3890 5 times, resulting in a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 105589.06495
Subtract 3695 from 3890 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 14:
1950 divided by 739 is 2 with a remainder of 472.
Put 2 as the next digit of the answer. 
Result so far: 105589.064952
The remainder is 472 after subtracting 1478 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 15:
The number 739 fits into 4720 6 times, leaving a remainder of 286.
Put 6 as the next digit of the answer. 
Result so far: 105589.0649526
If we take 4434 away from 4720, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 16:
If we divide 2860 by 739, we get 3 and a remainder of 643.
Record the quotient 3 as the next digit in the result. 
Result so far: 105589.06495263
Subtracting 2217 from 2860 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

The final result is 105589.06495263 with a remainder of 6.43e-07.
