28629762 ÷ 780 
The aim is to understand the frequency of 780 in 28629762.

On to step 1:
When dividing 2 by 780, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 780

Let's proceed to step 2:
780 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 780

Let's proceed to step 3:
780 can be fit into 286 0 times, resulting in a remainder of 286.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 286, we end up with 286.
Include the next digit (2) from the dividend after 286, then repeat: 2862 / 780

Advancing to step 4:
If we divide 2862 by 780, we get 3 and a remainder of 522.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2340 from 2862 and we're left with 522.
Grab the next digit (9) from the dividend, add it to 522, then carry on: 5229 / 780

Step 5:
If we divide 5229 by 780, we get 6 and a remainder of 549.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 549 after subtracting 4680 from 5229.
Grab the next digit (7) from the dividend, add it to 549, then carry on: 5497 / 780

Let's proceed to step 6:
5497 divided by 780 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 367.0
If we take 5460 away from 5497, we end up with 37.
Fetch the next digit (6) from the dividend, attach it to 37 and continue: 376 / 780

Advancing to step 7:
780 goes into 376 0 times with a remainder of 376.
The next digit of our result is 0. 
Result so far: 3670.0
Deduct 0 from 376 and we're left with 376.
Bring next digit (2) of the dividend behind the 376 and repeat the process: 3762 / 780

Step 8:
If we divide 3762 by 780, we get 4 and a remainder of 642.
Write down 4 as next digit of the result. 
Result so far: 36704.0
The remainder is 642 after subtracting 3120 from 3762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 9:
780 can be fit into 6420 8 times, resulting in a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 36704.8
If we take 6240 away from 6420, 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 10:
The number 780 fits into 1800 2 times, leaving a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 36704.82
Subtract 1560 from 1800 to 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.

Going ahead to step 11:
2400 divided by 780 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 36704.823
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.

Let's proceed to step 12:
780 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 36704.823
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.

Moving on to step 13:
780 goes into 6000 7 times with a remainder of 540.
Record the quotient 7 as the next digit in the result. 
Result so far: 36704.82307
Subtracting 5460 from 6000 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.

Let's proceed to step 14:
The number 780 fits into 5400 6 times, leaving a remainder of 720.
Use 6 as the next digit of our solution. 
Result so far: 36704.823076
If we take 4680 away from 5400, we end up with 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 15:
780 goes into 7200 9 times with a remainder of 180.
Use 9 as the next digit of our solution. 
Result so far: 36704.8230769
The remainder is 180 after subtracting 7020 from 7200.
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 16:
When dividing 1800 by 780, we get 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 36704.82307692
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.

The final result is 36704.82307692 with a remainder of 2.4e-07.
