We're dividing 78345960 by 505 
The aim is to understand the frequency of 505 in 78345960.

On to step 1:
If we divide 7 by 505, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 505

Advancing to step 2:
505 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 505

Step 3:
505 goes into 783 1 times with a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 278 after subtracting 505 from 783.
Take the next digit (4) from the dividend and append it to 278, then repeat: 2784 / 505

Moving on to step 4:
When dividing 2784 by 505, we get 5 with a remainder of 259.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2525 from 2784 leaves us with 259.
Fetch the next digit (5) from the dividend, attach it to 259 and continue: 2595 / 505

Moving on to step 5:
2595 divided by 505 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 155.0
The remainder is 70 after subtracting 2525 from 2595.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 505

Advancing to step 6:
505 goes into 709 1 times with a remainder of 204.
The number 1 becomes the next digit in our result. 
Result so far: 1551.0
If we take 505 away from 709, we end up with 204.
Bring next digit (6) of the dividend behind the 204 and repeat the process: 2046 / 505

Let's proceed to step 7:
2046 divided by 505 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 15514.0
Subtract 2020 from 2046 to get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 505

Moving on to step 8:
505 goes into 260 0 times with a remainder of 260.
The next digit of our result is 0. 
Result so far: 155140.0
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 9:
2600 divided by 505 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 155140.5
Subtract 2525 from 2600 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 10:
If we divide 750 by 505, we get 1 and a remainder of 245.
Put 1 as the next digit of the answer. 
Result so far: 155140.51
The remainder is 245 after subtracting 505 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 11:
If we divide 2450 by 505, we get 4 and a remainder of 430.
Put 4 as the next digit of the answer. 
Result so far: 155140.514
Subtract 2020 from 2450 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 12:
4300 divided by 505 is 8 with a remainder of 260.
The next digit of our result is 8. 
Result so far: 155140.5148
Subtract 4040 from 4300 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
2600 divided by 505 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 155140.51485
The remainder is 75 after subtracting 2525 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
When dividing 750 by 505, we get 1 with a remainder of 245.
The next digit of our result is 1. 
Result so far: 155140.514851
Deduct 505 from 750 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 15:
2450 divided by 505 is 4 with a remainder of 430.
The number 4 becomes the next digit in our result. 
Result so far: 155140.5148514
Subtract 2020 from 2450 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 16:
When dividing 4300 by 505, we get 8 with a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 155140.51485148
The remainder is 260 after subtracting 4040 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 155140.51485148 with a balance of 2.6e-07.
