Let's divide 10231111 by 780
The aim is to understand the frequency of 780 in 10231111.

Let's proceed to step 1:
1 divided by 780 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 780

On to step 2:
When dividing 10 by 780, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
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

Advancing to step 3:
If we divide 102 by 780, we get 0 and a remainder of 102.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 102, we end up with 102.
Take the next digit (3) from the dividend and append it to 102, then repeat: 1023 / 780

On to step 4:
If we divide 1023 by 780, we get 1 and a remainder of 243.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 780 from 1023 to get 243.
Grab the next digit (1) from the dividend, add it to 243, then carry on: 2431 / 780

Let's proceed to step 5:
The number 780 fits into 2431 3 times, leaving a remainder of 91.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 2340 from 2431, we get 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 780

Going ahead to step 6:
If we divide 911 by 780, we get 1 and a remainder of 131.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Deduct 780 from 911 and we're left with 131.
Grab the next digit (1) from the dividend, add it to 131, then carry on: 1311 / 780

Going ahead to step 7:
780 goes into 1311 1 times with a remainder of 531.
The next digit of our result is 1. 
Result so far: 1311.0
If we subtract 780 from 1311, we get 531.
Include the next digit (1) from the dividend after 531, then repeat: 5311 / 780

On to step 8:
The number 780 fits into 5311 6 times, leaving a remainder of 631.
Use 6 as the next digit of our solution. 
Result so far: 13116.0
Subtracting 4680 from 5311 leaves us with 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Step 9:
780 can be fit into 6310 8 times, resulting in a remainder of 70.
The next digit of our result is 8. 
Result so far: 13116.8
Deduct 6240 from 6310 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
If we divide 700 by 780, we get 0 and a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 13116.8
Subtract 0 from 700 to 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.

Advancing to step 11:
The number 780 fits into 7000 8 times, leaving a remainder of 760.
Record the quotient 8 as the next digit in the result. 
Result so far: 13116.808
The remainder is 760 after subtracting 6240 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 12:
7600 divided by 780 is 9 with a remainder of 580.
Put 9 as the next digit of the answer. 
Result so far: 13116.8089
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.

Step 13:
5800 divided by 780 is 7 with a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 13116.80897
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.

Moving on to step 14:
3400 divided by 780 is 4 with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 13116.808974
Subtracting 3120 from 3400 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
The number 780 fits into 2800 3 times, leaving a remainder of 460.
Use 3 as the next digit of our solution. 
Result so far: 13116.8089743
The remainder is 460 after subtracting 2340 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 16:
780 goes into 4600 5 times with a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 13116.80897435
Deduct 3900 from 4600 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 13116.80897435 with a remainder of 7e-07.
