Let's divide 29782938 by 780
The aim is to understand the frequency of 780 in 29782938.

On to step 1:
780 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 780

Moving on to step 2:
When dividing 29 by 780, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 780

On to step 3:
The number 780 fits into 297 0 times, leaving a remainder of 297.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 297, we get 297.
Include the next digit (8) from the dividend after 297, then repeat: 2978 / 780

Step 4:
780 can be fit into 2978 3 times, resulting in a remainder of 638.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2340 away from 2978, we end up with 638.
Fetch the next digit (2) from the dividend, attach it to 638 and continue: 6382 / 780

Step 5:
780 can be fit into 6382 8 times, resulting in a remainder of 142.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 6240 from 6382 to get 142.
Append the next digit (9) from the dividend to 142 and continue with: 1429 / 780

Advancing to step 6:
1429 divided by 780 is 1 with a remainder of 649.
The next digit of our result is 1. 
Result so far: 381.0
Subtract 780 from 1429 to get 649.
Take the next digit (3) from the dividend and append it to 649, then repeat: 6493 / 780

Moving on to step 7:
If we divide 6493 by 780, we get 8 and a remainder of 253.
Record the quotient 8 as the next digit in the result. 
Result so far: 3818.0
Deduct 6240 from 6493 and we're left with 253.
Bring next digit (8) of the dividend behind the 253 and repeat the process: 2538 / 780

On to step 8:
780 can be fit into 2538 3 times, resulting in a remainder of 198.
Write down 3 as next digit of the result. 
Result so far: 38183.0
If we take 2340 away from 2538, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 9:
When dividing 1980 by 780, we get 2 with a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 38183.2
The remainder is 420 after subtracting 1560 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
The number 780 fits into 4200 5 times, leaving a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 38183.25
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.

Step 11:
3000 divided by 780 is 3 with a remainder of 660.
The next digit of our result is 3. 
Result so far: 38183.253
If we subtract 2340 from 3000, we 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.

Let's proceed to step 12:
The number 780 fits into 6600 8 times, leaving a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 38183.2538
If we take 6240 away from 6600, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 13:
When dividing 3600 by 780, we get 4 with a remainder of 480.
Use 4 as the next digit of our solution. 
Result so far: 38183.25384
Subtract 3120 from 3600 to 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.

Let's proceed to step 14:
780 goes into 4800 6 times with a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 38183.253846
Deduct 4680 from 4800 and we're left 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.

Moving on to step 15:
The number 780 fits into 1200 1 times, leaving a remainder of 420.
The number 1 becomes the next digit in our result. 
Result so far: 38183.2538461
If we take 780 away from 1200, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 16:
780 can be fit into 4200 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 38183.25384615
If we take 3900 away from 4200, we end up 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.

The final outcome is 38183.25384615, with a leftover of 3e-07.
