85845130 ÷ 505 
We want to figure out the number of times 85845130 can be divided by 505.

On to step 1:
When dividing 8 by 505, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 505

On to step 2:
505 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 505

Step 3:
When dividing 858 by 505, we get 1 with a remainder of 353.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 353 after subtracting 505 from 858.
Bring next digit (4) of the dividend behind the 353 and repeat the process: 3534 / 505

Step 4:
When dividing 3534 by 505, we get 6 with a remainder of 504.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 3030 from 3534 leaves us with 504.
Append the next digit (5) from the dividend to 504 and continue with: 5045 / 505

Going ahead to step 5:
The number 505 fits into 5045 9 times, leaving a remainder of 500.
The next digit of our result is 9. 
Result so far: 169.0
Deduct 4545 from 5045 and we're left with 500.
Include the next digit (1) from the dividend after 500, then repeat: 5001 / 505

On to step 6:
505 goes into 5001 9 times with a remainder of 456.
Use 9 as the next digit of our solution. 
Result so far: 1699.0
If we subtract 4545 from 5001, we get 456.
Include the next digit (3) from the dividend after 456, then repeat: 4563 / 505

Let's proceed to step 7:
505 can be fit into 4563 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 16999.0
The remainder is 18 after subtracting 4545 from 4563.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 505

Moving on to step 8:
The number 505 fits into 180 0 times, leaving a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 169990.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 9:
The number 505 fits into 1800 3 times, leaving a remainder of 285.
Write down 3 as next digit of the result. 
Result so far: 169990.3
Deduct 1515 from 1800 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 10:
2850 divided by 505 is 5 with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 169990.35
The remainder is 325 after subtracting 2525 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 11:
The number 505 fits into 3250 6 times, leaving a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 169990.356
The remainder is 220 after subtracting 3030 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
When dividing 2200 by 505, we get 4 with a remainder of 180.
Record the quotient 4 as the next digit in the result. 
Result so far: 169990.3564
Subtracting 2020 from 2200 leaves us 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.

Going ahead to step 13:
If we divide 1800 by 505, we get 3 and a remainder of 285.
Use 3 as the next digit of our solution. 
Result so far: 169990.35643
Deduct 1515 from 1800 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 14:
505 can be fit into 2850 5 times, resulting in a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 169990.356435
Subtract 2525 from 2850 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 15:
If we divide 3250 by 505, we get 6 and a remainder of 220.
The number 6 becomes the next digit in our result. 
Result so far: 169990.3564356
If we take 3030 away from 3250, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 16:
If we divide 2200 by 505, we get 4 and a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 169990.35643564
If we take 2020 away from 2200, 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.

After the division, we end up with 169990.35643564 and a remainder of 1.8e-07.
