We divide 21596436 by 415
We want to figure out the number of times 21596436 can be divided by 415.

Step 1:
If we divide 2 by 415, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 415

Step 2:
21 divided by 415 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 415

Step 3:
The number 415 fits into 215 0 times, leaving a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Bring next digit (9) of the dividend behind the 215 and repeat the process: 2159 / 415

Step 4:
415 can be fit into 2159 5 times, resulting in a remainder of 84.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 2075 from 2159, we get 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 415

Advancing to step 5:
846 divided by 415 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 830 from 846, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 415

Going ahead to step 6:
164 divided by 415 is 0 with a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 520.0
If we subtract 0 from 164, we get 164.
Include the next digit (3) from the dividend after 164, then repeat: 1643 / 415

Let's proceed to step 7:
1643 divided by 415 is 3 with a remainder of 398.
Record the quotient 3 as the next digit in the result. 
Result so far: 5203.0
Subtracting 1245 from 1643 leaves us with 398.
Fetch the next digit (6) from the dividend, attach it to 398 and continue: 3986 / 415

Moving on to step 8:
415 goes into 3986 9 times with a remainder of 251.
Put 9 as the next digit of the answer. 
Result so far: 52039.0
If we take 3735 away from 3986, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 9:
When dividing 2510 by 415, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 52039.6
The remainder is 20 after subtracting 2490 from 2510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
415 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 52039.6
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
If we divide 2000 by 415, we get 4 and a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 52039.604
Deduct 1660 from 2000 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 12:
If we divide 3400 by 415, we get 8 and a remainder of 80.
The next digit of our result is 8. 
Result so far: 52039.6048
Deduct 3320 from 3400 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
When dividing 800 by 415, we get 1 with a remainder of 385.
The next digit of our result is 1. 
Result so far: 52039.60481
If we take 415 away from 800, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 14:
415 can be fit into 3850 9 times, resulting in a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 52039.604819
If we take 3735 away from 3850, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 15:
The number 415 fits into 1150 2 times, leaving a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 52039.6048192
The remainder is 320 after subtracting 830 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 16:
415 can be fit into 3200 7 times, resulting in a remainder of 295.
Put 7 as the next digit of the answer. 
Result so far: 52039.60481927
Subtracting 2905 from 3200 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 52039.60481927, and the remainder is 2.95e-07.
