We're dividing 40868564 by 780 
The aim is to understand the frequency of 780 in 40868564.

Let's proceed to step 1:
780 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 780

Advancing to step 2:
780 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 780

Step 3:
780 can be fit into 408 0 times, resulting in a remainder of 408.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 408 and we're left with 408.
Fetch the next digit (6) from the dividend, attach it to 408 and continue: 4086 / 780

Going ahead to step 4:
The number 780 fits into 4086 5 times, leaving a remainder of 186.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 3900 from 4086 and we're left with 186.
Bring next digit (8) of the dividend behind the 186 and repeat the process: 1868 / 780

On to step 5:
The number 780 fits into 1868 2 times, leaving a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 1560 from 1868, we get 308.
Append the next digit (5) from the dividend to 308 and continue with: 3085 / 780

Going ahead to step 6:
The number 780 fits into 3085 3 times, leaving a remainder of 745.
Use 3 as the next digit of our solution. 
Result so far: 523.0
If we take 2340 away from 3085, we end up with 745.
Append the next digit (6) from the dividend to 745 and continue with: 7456 / 780

Moving on to step 7:
780 can be fit into 7456 9 times, resulting in a remainder of 436.
Put 9 as the next digit of the answer. 
Result so far: 5239.0
Subtract 7020 from 7456 to get 436.
Include the next digit (4) from the dividend after 436, then repeat: 4364 / 780

Advancing to step 8:
780 goes into 4364 5 times with a remainder of 464.
The number 5 becomes the next digit in our result. 
Result so far: 52395.0
The remainder is 464 after subtracting 3900 from 4364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 9:
If we divide 4640 by 780, we get 5 and a remainder of 740.
The next digit of our result is 5. 
Result so far: 52395.5
If we take 3900 away from 4640, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 10:
780 can be fit into 7400 9 times, resulting in a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 52395.59
If we subtract 7020 from 7400, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
If we divide 3800 by 780, we get 4 and a remainder of 680.
Record the quotient 4 as the next digit in the result. 
Result so far: 52395.594
The remainder is 680 after subtracting 3120 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 12:
When dividing 6800 by 780, we get 8 with a remainder of 560.
Record the quotient 8 as the next digit in the result. 
Result so far: 52395.5948
Subtract 6240 from 6800 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 13:
5600 divided by 780 is 7 with a remainder of 140.
The number 7 becomes the next digit in our result. 
Result so far: 52395.59487
Subtracting 5460 from 5600 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
If we divide 1400 by 780, we get 1 and a remainder of 620.
The next digit of our result is 1. 
Result so far: 52395.594871
Subtracting 780 from 1400 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 15:
If we divide 6200 by 780, we get 7 and a remainder of 740.
Use 7 as the next digit of our solution. 
Result so far: 52395.5948717
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 16:
When dividing 7400 by 780, we get 9 with a remainder of 380.
Record the quotient 9 as the next digit in the result. 
Result so far: 52395.59487179
If we take 7020 away from 7400, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 52395.59487179, with a leftover of 3.8e-07.
