64044793 ÷ 780 
The aim is to understand the frequency of 780 in 64044793.

Advancing to step 1:
When dividing 6 by 780, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 780

Advancing to step 2:
When dividing 64 by 780, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 780

Going ahead to step 3:
780 goes into 640 0 times with a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 640 leaves us with 640.
Append the next digit (4) from the dividend to 640 and continue with: 6404 / 780

Step 4:
If we divide 6404 by 780, we get 8 and a remainder of 164.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6240 from 6404, we get 164.
Bring next digit (4) of the dividend behind the 164 and repeat the process: 1644 / 780

Let's proceed to step 5:
780 can be fit into 1644 2 times, resulting in a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 1560 from 1644 to get 84.
Grab the next digit (7) from the dividend, add it to 84, then carry on: 847 / 780

Going ahead to step 6:
When dividing 847 by 780, we get 1 with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 821.0
If we subtract 780 from 847, we get 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 780

Moving on to step 7:
If we divide 679 by 780, we get 0 and a remainder of 679.
The next digit of our result is 0. 
Result so far: 8210.0
If we take 0 away from 679, we end up with 679.
Append the next digit (3) from the dividend to 679 and continue with: 6793 / 780

Step 8:
When dividing 6793 by 780, we get 8 with a remainder of 553.
Put 8 as the next digit of the answer. 
Result so far: 82108.0
Subtracting 6240 from 6793 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 9:
780 can be fit into 5530 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 82108.7
If we subtract 5460 from 5530, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
The number 780 fits into 700 0 times, leaving a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 82108.7
Subtract 0 from 700 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.

On to step 11:
The number 780 fits into 7000 8 times, leaving a remainder of 760.
Use 8 as the next digit of our solution. 
Result so far: 82108.708
The remainder is 760 after subtracting 6240 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 12:
If we divide 7600 by 780, we get 9 and a remainder of 580.
Record the quotient 9 as the next digit in the result. 
Result so far: 82108.7089
Deduct 7020 from 7600 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 13:
780 goes into 5800 7 times with a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 82108.70897
Deduct 5460 from 5800 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 14:
780 can be fit into 3400 4 times, resulting in a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 82108.708974
Subtracting 3120 from 3400 leaves us 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.

Let's proceed to step 15:
If we divide 2800 by 780, we get 3 and a remainder of 460.
The number 3 becomes the next digit in our result. 
Result so far: 82108.7089743
The remainder is 460 after subtracting 2340 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 16:
When dividing 4600 by 780, we get 5 with a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 82108.70897435
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.

The final outcome is 82108.70897435, with a leftover of 7e-07.
