We're dividing 21078300 by 365 
Let's see how many times 365 fits into 21078300.

On to step 1:
365 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 365

Advancing to step 2:
When dividing 21 by 365, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 365

Advancing to step 3:
The number 365 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Include the next digit (7) from the dividend after 210, then repeat: 2107 / 365

On to step 4:
2107 divided by 365 is 5 with a remainder of 282.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 1825 from 2107 leaves us with 282.
Append the next digit (8) from the dividend to 282 and continue with: 2828 / 365

Moving on to step 5:
2828 divided by 365 is 7 with a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 273 after subtracting 2555 from 2828.
Fetch the next digit (3) from the dividend, attach it to 273 and continue: 2733 / 365

Advancing to step 6:
If we divide 2733 by 365, we get 7 and a remainder of 178.
Put 7 as the next digit of the answer. 
Result so far: 577.0
If we take 2555 away from 2733, we end up with 178.
Fetch the next digit (0) from the dividend, attach it to 178 and continue: 1780 / 365

Moving on to step 7:
365 goes into 1780 4 times with a remainder of 320.
The next digit of our result is 4. 
Result so far: 5774.0
If we take 1460 away from 1780, we end up with 320.
Append the next digit (0) from the dividend to 320 and continue with: 3200 / 365

Moving on to step 8:
3200 divided by 365 is 8 with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 57748.0
If we subtract 2920 from 3200, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 9:
2800 divided by 365 is 7 with a remainder of 245.
Record the quotient 7 as the next digit in the result. 
Result so far: 57748.7
The remainder is 245 after subtracting 2555 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 10:
When dividing 2450 by 365, we get 6 with a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 57748.76
If we subtract 2190 from 2450, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
The number 365 fits into 2600 7 times, leaving a remainder of 45.
The next digit of our result is 7. 
Result so far: 57748.767
Deduct 2555 from 2600 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
When dividing 450 by 365, we get 1 with a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 57748.7671
Deduct 365 from 450 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 13:
When dividing 850 by 365, we get 2 with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 57748.76712
Subtract 730 from 850 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
If we divide 1200 by 365, we get 3 and a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 57748.767123
The remainder is 105 after subtracting 1095 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 15:
365 can be fit into 1050 2 times, resulting in a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 57748.7671232
The remainder is 320 after subtracting 730 from 1050.
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:
The number 365 fits into 3200 8 times, leaving a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 57748.76712328
Subtract 2920 from 3200 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 57748.76712328 with a balance of 2.8e-07.
