We divide 78569773 by 505
The aim is to understand the frequency of 505 in 78569773.

On to step 1:
If we divide 7 by 505, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 505

Step 2:
The number 505 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 505

Step 3:
505 can be fit into 785 1 times, resulting in a remainder of 280.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 505 from 785 and we're left with 280.
Grab the next digit (6) from the dividend, add it to 280, then carry on: 2806 / 505

On to step 4:
2806 divided by 505 is 5 with a remainder of 281.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2525 from 2806 leaves us with 281.
Include the next digit (9) from the dividend after 281, then repeat: 2819 / 505

Going ahead to step 5:
505 can be fit into 2819 5 times, resulting in a remainder of 294.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we take 2525 away from 2819, we end up with 294.
Grab the next digit (7) from the dividend, add it to 294, then carry on: 2947 / 505

Moving on to step 6:
When dividing 2947 by 505, we get 5 with a remainder of 422.
The next digit of our result is 5. 
Result so far: 1555.0
Deduct 2525 from 2947 and we're left with 422.
Grab the next digit (7) from the dividend, add it to 422, then carry on: 4227 / 505

Step 7:
4227 divided by 505 is 8 with a remainder of 187.
The next digit of our result is 8. 
Result so far: 15558.0
Subtract 4040 from 4227 to get 187.
Grab the next digit (3) from the dividend, add it to 187, then carry on: 1873 / 505

Let's proceed to step 8:
505 goes into 1873 3 times with a remainder of 358.
The next digit of our result is 3. 
Result so far: 155583.0
Subtract 1515 from 1873 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 9:
The number 505 fits into 3580 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 155583.7
Subtract 3535 from 3580 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
When dividing 450 by 505, we get 0 with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 155583.7
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 11:
4500 divided by 505 is 8 with a remainder of 460.
Record the quotient 8 as the next digit in the result. 
Result so far: 155583.708
If we take 4040 away from 4500, we end up with 460.
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 12:
The number 505 fits into 4600 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 155583.7089
Subtracting 4545 from 4600 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
550 divided by 505 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 155583.70891
Deduct 505 from 550 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
505 can be fit into 450 0 times, resulting in a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 155583.70891
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
When dividing 4500 by 505, we get 8 with a remainder of 460.
Write down 8 as next digit of the result. 
Result so far: 155583.7089108
Subtract 4040 from 4500 to 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.

Moving on to step 16:
If we divide 4600 by 505, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 155583.70891089
If we take 4545 away from 4600, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The quotient of the division is 155583.70891089, and the remainder is 5.5e-08.
