21173415 divided by 605 
We want to figure out the number of times 21173415 can be divided by 605.

Going ahead to step 1:
The number 605 fits into 2 0 times, leaving 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 605

Step 2:
When dividing 21 by 605, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 605

Moving on to step 3:
The number 605 fits into 211 0 times, leaving a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 211, we get 211.
Include the next digit (7) from the dividend after 211, then repeat: 2117 / 605

Going ahead to step 4:
The number 605 fits into 2117 3 times, leaving a remainder of 302.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1815 from 2117 to get 302.
Append the next digit (3) from the dividend to 302 and continue with: 3023 / 605

Going ahead to step 5:
605 goes into 3023 4 times with a remainder of 603.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Deduct 2420 from 3023 and we're left with 603.
Append the next digit (4) from the dividend to 603 and continue with: 6034 / 605

Advancing to step 6:
When dividing 6034 by 605, we get 9 with a remainder of 589.
Use 9 as the next digit of our solution. 
Result so far: 349.0
If we take 5445 away from 6034, we end up with 589.
Bring next digit (1) of the dividend behind the 589 and repeat the process: 5891 / 605

Going ahead to step 7:
605 goes into 5891 9 times with a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 3499.0
If we subtract 5445 from 5891, we get 446.
Fetch the next digit (5) from the dividend, attach it to 446 and continue: 4465 / 605

On to step 8:
605 can be fit into 4465 7 times, resulting in a remainder of 230.
Write down 7 as next digit of the result. 
Result so far: 34997.0
If we take 4235 away from 4465, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 9:
When dividing 2300 by 605, we get 3 with a remainder of 485.
The number 3 becomes the next digit in our result. 
Result so far: 34997.3
If we take 1815 away from 2300, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

On to step 10:
605 goes into 4850 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 34997.38
If we take 4840 away from 4850, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 605, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 34997.38
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
If we divide 1000 by 605, we get 1 and a remainder of 395.
The number 1 becomes the next digit in our result. 
Result so far: 34997.3801
Subtracting 605 from 1000 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 13:
3950 divided by 605 is 6 with a remainder of 320.
Put 6 as the next digit of the answer. 
Result so far: 34997.38016
Subtracting 3630 from 3950 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
605 can be fit into 3200 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 34997.380165
The remainder is 175 after subtracting 3025 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 15:
The number 605 fits into 1750 2 times, leaving a remainder of 540.
Put 2 as the next digit of the answer. 
Result so far: 34997.3801652
If we take 1210 away from 1750, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 16:
If we divide 5400 by 605, we get 8 and a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 34997.38016528
If we subtract 4840 from 5400, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 34997.38016528 and a remainder of 5.6e-07.
