10260927 ÷ 780 
The aim is to understand the frequency of 780 in 10260927.

Let's proceed to step 1:
780 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 780

Advancing to step 2:
10 divided by 780 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 780

Let's proceed to step 3:
If we divide 102 by 780, we get 0 and a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 102, we get 102.
Bring next digit (6) of the dividend behind the 102 and repeat the process: 1026 / 780

Going ahead to step 4:
If we divide 1026 by 780, we get 1 and a remainder of 246.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 780 away from 1026, we end up with 246.
Take the next digit (0) from the dividend and append it to 246, then repeat: 2460 / 780

Going ahead to step 5:
The number 780 fits into 2460 3 times, leaving a remainder of 120.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 2340 away from 2460, we end up with 120.
Take the next digit (9) from the dividend and append it to 120, then repeat: 1209 / 780

On to step 6:
1209 divided by 780 is 1 with a remainder of 429.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we take 780 away from 1209, we end up with 429.
Bring next digit (2) of the dividend behind the 429 and repeat the process: 4292 / 780

On to step 7:
The number 780 fits into 4292 5 times, leaving a remainder of 392.
Record the quotient 5 as the next digit in the result. 
Result so far: 1315.0
If we subtract 3900 from 4292, we get 392.
Grab the next digit (7) from the dividend, add it to 392, then carry on: 3927 / 780

On to step 8:
3927 divided by 780 is 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 13155.0
If we subtract 3900 from 3927, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 780 is 0 with a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 13155.0
If we take 0 away from 270, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
When dividing 2700 by 780, we get 3 with a remainder of 360.
Record the quotient 3 as the next digit in the result. 
Result so far: 13155.03
The remainder is 360 after subtracting 2340 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
The number 780 fits into 3600 4 times, leaving a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 13155.034
If we subtract 3120 from 3600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
The number 780 fits into 4800 6 times, leaving a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 13155.0346
If we take 4680 away from 4800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
If we divide 1200 by 780, we get 1 and a remainder of 420.
Use 1 as the next digit of our solution. 
Result so far: 13155.03461
If we subtract 780 from 1200, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 14:
If we divide 4200 by 780, we get 5 and a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 13155.034615
Subtracting 3900 from 4200 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
When dividing 3000 by 780, we get 3 with a remainder of 660.
Use 3 as the next digit of our solution. 
Result so far: 13155.0346153
Subtract 2340 from 3000 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 16:
The number 780 fits into 6600 8 times, leaving a remainder of 360.
The next digit of our result is 8. 
Result so far: 13155.03461538
Subtract 6240 from 6600 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 13155.03461538 with a remaining 3.6e-07.
