21239673 divided by 365 
Our goal is to divide 21239673 by 365.

On to step 1:
365 goes into 2 0 times with 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.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 365

Step 2:
When dividing 21 by 365, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 365

On to step 3:
365 can be fit into 212 0 times, resulting in a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Include the next digit (3) from the dividend after 212, then repeat: 2123 / 365

Let's proceed to step 4:
The number 365 fits into 2123 5 times, leaving a remainder of 298.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 1825 from 2123 to get 298.
Include the next digit (9) from the dividend after 298, then repeat: 2989 / 365

Moving on to step 5:
2989 divided by 365 is 8 with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 2920 from 2989 leaves us with 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 365

Going ahead to step 6:
696 divided by 365 is 1 with a remainder of 331.
The next digit of our result is 1. 
Result so far: 581.0
Subtract 365 from 696 to get 331.
Grab the next digit (7) from the dividend, add it to 331, then carry on: 3317 / 365

Step 7:
3317 divided by 365 is 9 with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 5819.0
Deduct 3285 from 3317 and we're left with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 365

Moving on to step 8:
365 goes into 323 0 times with a remainder of 323.
Put 0 as the next digit of the answer. 
Result so far: 58190.0
The remainder is 323 after subtracting 0 from 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 9:
When dividing 3230 by 365, we get 8 with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 58190.8
Subtracting 2920 from 3230 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
365 goes into 3100 8 times with a remainder of 180.
Record the quotient 8 as the next digit in the result. 
Result so far: 58190.88
Subtract 2920 from 3100 to 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.

The quotient of the division is 58190.88, and the remainder is 0.18.
