50646760 divided by 780 
The aim is to understand the frequency of 780 in 50646760.

On to step 1:
780 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 780

Let's proceed to step 2:
The number 780 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 780

Let's proceed to step 3:
780 goes into 506 0 times with a remainder of 506.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 506 to get 506.
Append the next digit (4) from the dividend to 506 and continue with: 5064 / 780

Going ahead to step 4:
If we divide 5064 by 780, we get 6 and a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 384 after subtracting 4680 from 5064.
Include the next digit (6) from the dividend after 384, then repeat: 3846 / 780

Advancing to step 5:
780 goes into 3846 4 times with a remainder of 726.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 3120 away from 3846, we end up with 726.
Fetch the next digit (7) from the dividend, attach it to 726 and continue: 7267 / 780

Moving on to step 6:
When dividing 7267 by 780, we get 9 with a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 649.0
If we subtract 7020 from 7267, we get 247.
Fetch the next digit (6) from the dividend, attach it to 247 and continue: 2476 / 780

Advancing to step 7:
When dividing 2476 by 780, we get 3 with a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 6493.0
Deduct 2340 from 2476 and we're left with 136.
Grab the next digit (0) from the dividend, add it to 136, then carry on: 1360 / 780

Going ahead to step 8:
The number 780 fits into 1360 1 times, leaving a remainder of 580.
Use 1 as the next digit of our solution. 
Result so far: 64931.0
Subtracting 780 from 1360 leaves us 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 9:
5800 divided by 780 is 7 with a remainder of 340.
The number 7 becomes the next digit in our result. 
Result so far: 64931.7
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.

On to step 10:
If we divide 3400 by 780, we get 4 and a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 64931.74
The remainder is 280 after subtracting 3120 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
If we divide 2800 by 780, we get 3 and a remainder of 460.
Write down 3 as next digit of the result. 
Result so far: 64931.743
If we take 2340 away from 2800, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
The number 780 fits into 4600 5 times, leaving a remainder of 700.
Use 5 as the next digit of our solution. 
Result so far: 64931.7435
If we subtract 3900 from 4600, we 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 13:
The number 780 fits into 7000 8 times, leaving a remainder of 760.
Put 8 as the next digit of the answer. 
Result so far: 64931.74358
If we take 6240 away from 7000, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 14:
The number 780 fits into 7600 9 times, leaving a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 64931.743589
Subtract 7020 from 7600 to get 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 15:
The number 780 fits into 5800 7 times, leaving a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 64931.7435897
Subtracting 5460 from 5800 leaves us 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.

On to step 16:
If we divide 3400 by 780, we get 4 and a remainder of 280.
The next digit of our result is 4. 
Result so far: 64931.74358974
The remainder is 280 after subtracting 3120 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 64931.74358974 with a remainder of 2.8e-07.
