We divide 17683984 by 780
The aim is to understand the frequency of 780 in 17683984.

On to step 1:
The number 780 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 780

Advancing to step 2:
17 divided by 780 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 780

Advancing to step 3:
780 can be fit into 176 0 times, resulting in a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 176 after subtracting 0 from 176.
Take the next digit (8) from the dividend and append it to 176, then repeat: 1768 / 780

Let's proceed to step 4:
When dividing 1768 by 780, we get 2 with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1560 from 1768 to get 208.
Append the next digit (3) from the dividend to 208 and continue with: 2083 / 780

Moving on to step 5:
When dividing 2083 by 780, we get 2 with a remainder of 523.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 1560 away from 2083, we end up with 523.
Fetch the next digit (9) from the dividend, attach it to 523 and continue: 5239 / 780

Let's proceed to step 6:
5239 divided by 780 is 6 with a remainder of 559.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Deduct 4680 from 5239 and we're left with 559.
Append the next digit (8) from the dividend to 559 and continue with: 5598 / 780

Advancing to step 7:
If we divide 5598 by 780, we get 7 and a remainder of 138.
The next digit of our result is 7. 
Result so far: 2267.0
Deduct 5460 from 5598 and we're left with 138.
Append the next digit (4) from the dividend to 138 and continue with: 1384 / 780

On to step 8:
780 can be fit into 1384 1 times, resulting in a remainder of 604.
Use 1 as the next digit of our solution. 
Result so far: 22671.0
The remainder is 604 after subtracting 780 from 1384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 9:
The number 780 fits into 6040 7 times, leaving a remainder of 580.
Write down 7 as next digit of the result. 
Result so far: 22671.7
Deduct 5460 from 6040 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.

Moving on to step 10:
If we divide 5800 by 780, we get 7 and a remainder of 340.
The number 7 becomes the next digit in our result. 
Result so far: 22671.77
If we take 5460 away from 5800, we end up 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.

The final outcome is 22671.77, with a leftover of 0.34.
