We look at the division of 84315401 by 505 
Let's see how many times 505 fits into 84315401.

Let's proceed 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
Subtracting 0 from 8 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 505

Moving on to step 2:
505 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 505

Advancing to step 3:
The number 505 fits into 843 1 times, leaving a remainder of 338.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 505 from 843 leaves us with 338.
Bring next digit (1) of the dividend behind the 338 and repeat the process: 3381 / 505

Advancing to step 4:
505 goes into 3381 6 times with a remainder of 351.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 3030 from 3381 and we're left with 351.
Fetch the next digit (5) from the dividend, attach it to 351 and continue: 3515 / 505

Going ahead to step 5:
3515 divided by 505 is 6 with a remainder of 485.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
If we take 3030 away from 3515, we end up with 485.
Bring next digit (4) of the dividend behind the 485 and repeat the process: 4854 / 505

On to step 6:
When dividing 4854 by 505, we get 9 with a remainder of 309.
Put 9 as the next digit of the answer. 
Result so far: 1669.0
If we take 4545 away from 4854, we end up with 309.
Include the next digit (0) from the dividend after 309, then repeat: 3090 / 505

On to step 7:
The number 505 fits into 3090 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 16696.0
The remainder is 60 after subtracting 3030 from 3090.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 505

On to step 8:
If we divide 601 by 505, we get 1 and a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 166961.0
Deduct 505 from 601 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 505 fits into 960 1 times, leaving a remainder of 455.
Put 1 as the next digit of the answer. 
Result so far: 166961.1
Subtract 505 from 960 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 10:
505 goes into 4550 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 166961.19
Deduct 4545 from 4550 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
The number 505 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 166961.19
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
500 divided by 505 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 166961.19
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 166961.19, and the remainder is 0.005.
