Let's divide 42048261 by 780
The aim is to understand the frequency of 780 in 42048261.

On to step 1:
780 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 780

Advancing to step 2:
When dividing 42 by 780, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 780

On to step 3:
When dividing 420 by 780, we get 0 with a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Grab the next digit (4) from the dividend, add it to 420, then carry on: 4204 / 780

Moving on to step 4:
780 goes into 4204 5 times with a remainder of 304.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 304 after subtracting 3900 from 4204.
Bring next digit (8) of the dividend behind the 304 and repeat the process: 3048 / 780

Advancing to step 5:
3048 divided by 780 is 3 with a remainder of 708.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 2340 from 3048 to get 708.
Fetch the next digit (2) from the dividend, attach it to 708 and continue: 7082 / 780

Moving on to step 6:
7082 divided by 780 is 9 with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 539.0
Subtract 7020 from 7082 to get 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 780

Going ahead to step 7:
780 can be fit into 626 0 times, resulting in a remainder of 626.
The next digit of our result is 0. 
Result so far: 5390.0
Subtract 0 from 626 to get 626.
Fetch the next digit (1) from the dividend, attach it to 626 and continue: 6261 / 780

On to step 8:
6261 divided by 780 is 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 53908.0
Subtract 6240 from 6261 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 780, we get 0 with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 53908.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
When dividing 2100 by 780, we get 2 with a remainder of 540.
The number 2 becomes the next digit in our result. 
Result so far: 53908.02
Subtracting 1560 from 2100 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
When dividing 5400 by 780, we get 6 with a remainder of 720.
The next digit of our result is 6. 
Result so far: 53908.026
If we subtract 4680 from 5400, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 12:
The number 780 fits into 7200 9 times, leaving a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 53908.0269
If we take 7020 away from 7200, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
If we divide 1800 by 780, we get 2 and a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 53908.02692
If we subtract 1560 from 1800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
2400 divided by 780 is 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 53908.026923
If we subtract 2340 from 2400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 15:
When dividing 600 by 780, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 53908.026923
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 16:
780 goes into 6000 7 times with a remainder of 540.
Use 7 as the next digit of our solution. 
Result so far: 53908.02692307
Deduct 5460 from 6000 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Our division results in 53908.02692307 with a remaining 5.4e-07.
