We look at the division of 76448305 by 780 
The aim is to understand the frequency of 780 in 76448305.

Step 1:
When dividing 7 by 780, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 780

On to step 2:
The number 780 fits into 76 0 times, leaving a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 780

Moving on to step 3:
When dividing 764 by 780, we get 0 with a remainder of 764.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 764 and we're left with 764.
Grab the next digit (4) from the dividend, add it to 764, then carry on: 7644 / 780

Let's proceed to step 4:
7644 divided by 780 is 9 with a remainder of 624.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7020 from 7644 leaves us with 624.
Append the next digit (8) from the dividend to 624 and continue with: 6248 / 780

Let's proceed to step 5:
If we divide 6248 by 780, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtract 6240 from 6248 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 780

On to step 6:
The number 780 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 980.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 780

Let's proceed to step 7:
The number 780 fits into 830 1 times, leaving a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 9801.0
Subtract 780 from 830 to get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 780

Let's proceed to step 8:
780 can be fit into 505 0 times, resulting in a remainder of 505.
Record the quotient 0 as the next digit in the result. 
Result so far: 98010.0
If we subtract 0 from 505, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 9:
If we divide 5050 by 780, we get 6 and a remainder of 370.
Write down 6 as next digit of the result. 
Result so far: 98010.6
The remainder is 370 after subtracting 4680 from 5050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
3700 divided by 780 is 4 with a remainder of 580.
The next digit of our result is 4. 
Result so far: 98010.64
The remainder is 580 after subtracting 3120 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 11:
780 can be fit into 5800 7 times, resulting in a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 98010.647
The remainder is 340 after subtracting 5460 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
The number 780 fits into 3400 4 times, leaving a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 98010.6474
If we take 3120 away from 3400, we end up 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.

Step 13:
When dividing 2800 by 780, we get 3 with a remainder of 460.
Record the quotient 3 as the next digit in the result. 
Result so far: 98010.64743
If we take 2340 away from 2800, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 14:
If we divide 4600 by 780, we get 5 and a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 98010.647435
Subtract 3900 from 4600 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 15:
780 can be fit into 7000 8 times, resulting in a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 98010.6474358
If we take 6240 away from 7000, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 16:
780 goes into 7600 9 times with a remainder of 580.
Record the quotient 9 as the next digit in the result. 
Result so far: 98010.64743589
If we subtract 7020 from 7600, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

In conclusion, the division gives 98010.64743589 with a balance of 5.8e-07.
