Let's divide 21774515 by 865
Let's see how many times 865 fits into 21774515.

Advancing to step 1:
If we divide 2 by 865, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 865

On to step 2:
If we divide 21 by 865, we get 0 and 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.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 865

Let's proceed to step 3:
217 divided by 865 is 0 with a remainder of 217.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 217 after subtracting 0 from 217.
Fetch the next digit (7) from the dividend, attach it to 217 and continue: 2177 / 865

Advancing to step 4:
865 goes into 2177 2 times with a remainder of 447.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1730 from 2177, we get 447.
Fetch the next digit (4) from the dividend, attach it to 447 and continue: 4474 / 865

On to step 5:
When dividing 4474 by 865, we get 5 with a remainder of 149.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 4325 from 4474 and we're left with 149.
Bring next digit (5) of the dividend behind the 149 and repeat the process: 1495 / 865

Let's proceed to step 6:
865 goes into 1495 1 times with a remainder of 630.
Use 1 as the next digit of our solution. 
Result so far: 251.0
If we subtract 865 from 1495, we get 630.
Append the next digit (1) from the dividend to 630 and continue with: 6301 / 865

On to step 7:
6301 divided by 865 is 7 with a remainder of 246.
The number 7 becomes the next digit in our result. 
Result so far: 2517.0
If we subtract 6055 from 6301, we get 246.
Grab the next digit (5) from the dividend, add it to 246, then carry on: 2465 / 865

Going ahead to step 8:
When dividing 2465 by 865, we get 2 with a remainder of 735.
The number 2 becomes the next digit in our result. 
Result so far: 25172.0
Deduct 1730 from 2465 and we're left with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

On to step 9:
7350 divided by 865 is 8 with a remainder of 430.
Write down 8 as next digit of the result. 
Result so far: 25172.8
Subtracting 6920 from 7350 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 10:
The number 865 fits into 4300 4 times, leaving a remainder of 840.
The next digit of our result is 4. 
Result so far: 25172.84
Subtracting 3460 from 4300 leaves us with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 11:
When dividing 8400 by 865, we get 9 with a remainder of 615.
The next digit of our result is 9. 
Result so far: 25172.849
Deduct 7785 from 8400 and we're left with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Advancing to step 12:
865 can be fit into 6150 7 times, resulting in a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 25172.8497
Subtracting 6055 from 6150 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
950 divided by 865 is 1 with a remainder of 85.
The next digit of our result is 1. 
Result so far: 25172.84971
Deduct 865 from 950 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.

Going ahead to step 14:
865 goes into 850 0 times with a remainder of 850.
The next digit of our result is 0. 
Result so far: 25172.84971
The remainder is 850 after subtracting 0 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 15:
865 can be fit into 8500 9 times, resulting in a remainder of 715.
The next digit of our result is 9. 
Result so far: 25172.8497109
The remainder is 715 after subtracting 7785 from 8500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 16:
The number 865 fits into 7150 8 times, leaving a remainder of 230.
Record the quotient 8 as the next digit in the result. 
Result so far: 25172.84971098
If we subtract 6920 from 7150, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 25172.84971098 and a remainder of 2.3e-07.
