We look at the division of 75336247 by 780 
The aim is to understand the frequency of 780 in 75336247.

Moving on to step 1:
The number 780 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 780

Advancing to step 2:
75 divided by 780 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 780

On to step 3:
The number 780 fits into 753 0 times, leaving a remainder of 753.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 753, we get 753.
Include the next digit (3) from the dividend after 753, then repeat: 7533 / 780

Step 4:
The number 780 fits into 7533 9 times, leaving a remainder of 513.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7020 from 7533 leaves us with 513.
Take the next digit (6) from the dividend and append it to 513, then repeat: 5136 / 780

Step 5:
When dividing 5136 by 780, we get 6 with a remainder of 456.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Deduct 4680 from 5136 and we're left with 456.
Fetch the next digit (2) from the dividend, attach it to 456 and continue: 4562 / 780

Step 6:
780 can be fit into 4562 5 times, resulting in a remainder of 662.
Write down 5 as next digit of the result. 
Result so far: 965.0
If we take 3900 away from 4562, we end up with 662.
Append the next digit (4) from the dividend to 662 and continue with: 6624 / 780

On to step 7:
When dividing 6624 by 780, we get 8 with a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 9658.0
If we take 6240 away from 6624, we end up with 384.
Append the next digit (7) from the dividend to 384 and continue with: 3847 / 780

Let's proceed to step 8:
When dividing 3847 by 780, we get 4 with a remainder of 727.
The number 4 becomes the next digit in our result. 
Result so far: 96584.0
If we take 3120 away from 3847, we end up with 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Advancing to step 9:
780 goes into 7270 9 times with a remainder of 250.
Write down 9 as next digit of the result. 
Result so far: 96584.9
If we take 7020 away from 7270, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
2500 divided by 780 is 3 with a remainder of 160.
The next digit of our result is 3. 
Result so far: 96584.93
If we subtract 2340 from 2500, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
When dividing 1600 by 780, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 96584.932
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
780 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 96584.932
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
When dividing 4000 by 780, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 96584.93205
If we take 3900 away from 4000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 14:
780 can be fit into 1000 1 times, resulting in a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 96584.932051
If we subtract 780 from 1000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 15:
If we divide 2200 by 780, we get 2 and a remainder of 640.
Record the quotient 2 as the next digit in the result. 
Result so far: 96584.9320512
If we take 1560 away from 2200, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
780 can be fit into 6400 8 times, resulting in a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 96584.93205128
Deduct 6240 from 6400 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 96584.93205128 with a remaining 1.6e-07.
