We divide 21957930 by 270
We want to figure out the number of times 21957930 can be divided by 270.

Advancing to step 1:
2 divided by 270 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 270

Advancing to step 2:
21 divided by 270 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 270

Going ahead to step 3:
The number 270 fits into 219 0 times, leaving a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Grab the next digit (5) from the dividend, add it to 219, then carry on: 2195 / 270

Advancing to step 4:
2195 divided by 270 is 8 with a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 2160 from 2195 leaves us with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 270

Moving on to step 5:
The number 270 fits into 357 1 times, leaving a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 270 from 357 leaves us with 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 270

Let's proceed to step 6:
879 divided by 270 is 3 with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 813.0
The remainder is 69 after subtracting 810 from 879.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 270

On to step 7:
The number 270 fits into 693 2 times, leaving a remainder of 153.
The number 2 becomes the next digit in our result. 
Result so far: 8132.0
Deduct 540 from 693 and we're left with 153.
Take the next digit (0) from the dividend and append it to 153, then repeat: 1530 / 270

Going ahead to step 8:
270 goes into 1530 5 times with a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 81325.0
If we subtract 1350 from 1530, we 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.

On to step 9:
If we divide 1800 by 270, we get 6 and a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 81325.6
If we take 1620 away from 1800, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
The number 270 fits into 1800 6 times, leaving a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 81325.66
Subtracting 1620 from 1800 leaves us with 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 81325.66, and the remainder is 0.18.
