We divide 21872392 by 270
We want to divide 21872392 by 270.

Step 1:
The number 270 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 270

Moving on to step 2:
The number 270 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 270

Advancing to step 3:
If we divide 218 by 270, we get 0 and a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Grab the next digit (7) from the dividend, add it to 218, then carry on: 2187 / 270

Going ahead to step 4:
When dividing 2187 by 270, we get 8 with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 2160 from 2187 to get 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 270

Moving on to step 5:
270 goes into 272 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 270 from 272 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 270

On to step 6:
The number 270 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 810.0
If we take 0 away from 23, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 270

Step 7:
270 goes into 239 0 times with a remainder of 239.
The next digit of our result is 0. 
Result so far: 8100.0
If we subtract 0 from 239, we get 239.
Append the next digit (2) from the dividend to 239 and continue with: 2392 / 270

Let's proceed to step 8:
270 goes into 2392 8 times with a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 81008.0
If we take 2160 away from 2392, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 9:
270 goes into 2320 8 times with a remainder of 160.
The next digit of our result is 8. 
Result so far: 81008.8
Subtract 2160 from 2320 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
If we divide 1600 by 270, we get 5 and a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 81008.85
Subtract 1350 from 1600 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 11:
When dividing 2500 by 270, we get 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 81008.859
The remainder is 70 after subtracting 2430 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
700 divided by 270 is 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 81008.8592
Subtract 540 from 700 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 13:
When dividing 1600 by 270, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 81008.85925
Subtract 1350 from 1600 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
When dividing 2500 by 270, we get 9 with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 81008.859259
If we take 2430 away from 2500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 15:
270 goes into 700 2 times with a remainder of 160.
The next digit of our result is 2. 
Result so far: 81008.8592592
Subtract 540 from 700 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 16:
270 can be fit into 1600 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 81008.85925925
The remainder is 250 after subtracting 1350 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 81008.85925925 with a remainder of 2.5e-07.
