Let's divide 21615367 by 505
We're looking to find how many times 505 goes into 21615367.

Moving on to step 1:
If we divide 2 by 505, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 505

Moving on to step 2:
When dividing 21 by 505, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 505

Step 3:
505 can be fit into 216 0 times, resulting in a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Grab the next digit (1) from the dividend, add it to 216, then carry on: 2161 / 505

Let's proceed to step 4:
When dividing 2161 by 505, we get 4 with a remainder of 141.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2020 away from 2161, we end up with 141.
Include the next digit (5) from the dividend after 141, then repeat: 1415 / 505

Step 5:
The number 505 fits into 1415 2 times, leaving a remainder of 405.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 1010 from 1415 leaves us with 405.
Include the next digit (3) from the dividend after 405, then repeat: 4053 / 505

Advancing to step 6:
505 can be fit into 4053 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 428.0
Subtract 4040 from 4053 to get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 505

Moving on to step 7:
505 goes into 136 0 times with a remainder of 136.
Put 0 as the next digit of the answer. 
Result so far: 4280.0
If we subtract 0 from 136, we get 136.
Include the next digit (7) from the dividend after 136, then repeat: 1367 / 505

Moving on to step 8:
The number 505 fits into 1367 2 times, leaving a remainder of 357.
Use 2 as the next digit of our solution. 
Result so far: 42802.0
Subtract 1010 from 1367 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 9:
If we divide 3570 by 505, we get 7 and a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 42802.7
The remainder is 35 after subtracting 3535 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
When dividing 350 by 505, we get 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 42802.7
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 11:
3500 divided by 505 is 6 with a remainder of 470.
Record the quotient 6 as the next digit in the result. 
Result so far: 42802.706
Subtract 3030 from 3500 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 12:
The number 505 fits into 4700 9 times, leaving a remainder of 155.
Put 9 as the next digit of the answer. 
Result so far: 42802.7069
If we take 4545 away from 4700, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 13:
505 goes into 1550 3 times with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 42802.70693
Subtracting 1515 from 1550 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
505 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 42802.70693
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 15:
3500 divided by 505 is 6 with a remainder of 470.
Record the quotient 6 as the next digit in the result. 
Result so far: 42802.7069306
Subtracting 3030 from 3500 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 16:
The number 505 fits into 4700 9 times, leaving a remainder of 155.
The next digit of our result is 9. 
Result so far: 42802.70693069
If we subtract 4545 from 4700, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 42802.70693069 with a remaining 1.55e-07.
