Let's divide 33546820 by 780
The aim is to understand the frequency of 780 in 33546820.

Advancing to step 1:
If we divide 3 by 780, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 780

Going ahead to step 2:
If we divide 33 by 780, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 780

Moving on to step 3:
When dividing 335 by 780, we get 0 with a remainder of 335.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 335 and we're left with 335.
Bring next digit (4) of the dividend behind the 335 and repeat the process: 3354 / 780

Step 4:
780 can be fit into 3354 4 times, resulting in a remainder of 234.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3120 from 3354 leaves us with 234.
Fetch the next digit (6) from the dividend, attach it to 234 and continue: 2346 / 780

Going ahead to step 5:
780 can be fit into 2346 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 6 after subtracting 2340 from 2346.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 780

On to step 6:
If we divide 68 by 780, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 430.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 780

Moving on to step 7:
682 divided by 780 is 0 with a remainder of 682.
Put 0 as the next digit of the answer. 
Result so far: 4300.0
The remainder is 682 after subtracting 0 from 682.
Grab the next digit (0) from the dividend, add it to 682, then carry on: 6820 / 780

Going ahead to step 8:
When dividing 6820 by 780, we get 8 with a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 43008.0
Subtract 6240 from 6820 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.

Let's proceed to step 9:
If we divide 5800 by 780, we get 7 and a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 43008.7
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.

Let's proceed to step 10:
780 goes into 3400 4 times with a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 43008.74
Deduct 3120 from 3400 and we're left 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.

Advancing to step 11:
If we divide 2800 by 780, we get 3 and a remainder of 460.
The next digit of our result is 3. 
Result so far: 43008.743
If we subtract 2340 from 2800, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 12:
4600 divided by 780 is 5 with a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 43008.7435
Subtracting 3900 from 4600 leaves us 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.

Step 13:
780 goes into 7000 8 times with a remainder of 760.
The next digit of our result is 8. 
Result so far: 43008.74358
Deduct 6240 from 7000 and we're left 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.

On to step 14:
7600 divided by 780 is 9 with a remainder of 580.
Use 9 as the next digit of our solution. 
Result so far: 43008.743589
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.

Going ahead to step 15:
5800 divided by 780 is 7 with a remainder of 340.
Write down 7 as next digit of the result. 
Result so far: 43008.7435897
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.

Step 16:
If we divide 3400 by 780, we get 4 and a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 43008.74358974
If we subtract 3120 from 3400, we get 280.
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 43008.74358974 with a remainder of 2.8e-07.
