We look at the division of 21912924 by 808 
Let's see how many times 808 fits into 21912924.

On to step 1:
When dividing 2 by 808, we get 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 808

Going ahead to step 2:
808 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 808

On to step 3:
808 goes into 219 0 times with a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 219, we end up with 219.
Bring next digit (1) of the dividend behind the 219 and repeat the process: 2191 / 808

Going ahead to step 4:
808 goes into 2191 2 times with a remainder of 575.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1616 from 2191 and we're left with 575.
Fetch the next digit (2) from the dividend, attach it to 575 and continue: 5752 / 808

Advancing to step 5:
5752 divided by 808 is 7 with a remainder of 96.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we subtract 5656 from 5752, we get 96.
Grab the next digit (9) from the dividend, add it to 96, then carry on: 969 / 808

Moving on to step 6:
The number 808 fits into 969 1 times, leaving a remainder of 161.
The next digit of our result is 1. 
Result so far: 271.0
Deduct 808 from 969 and we're left with 161.
Grab the next digit (2) from the dividend, add it to 161, then carry on: 1612 / 808

Going ahead to step 7:
If we divide 1612 by 808, we get 1 and a remainder of 804.
Use 1 as the next digit of our solution. 
Result so far: 2711.0
If we subtract 808 from 1612, we get 804.
Grab the next digit (4) from the dividend, add it to 804, then carry on: 8044 / 808

Going ahead to step 8:
808 goes into 8044 9 times with a remainder of 772.
Record the quotient 9 as the next digit in the result. 
Result so far: 27119.0
If we subtract 7272 from 8044, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

On to step 9:
7720 divided by 808 is 9 with a remainder of 448.
Record the quotient 9 as the next digit in the result. 
Result so far: 27119.9
The remainder is 448 after subtracting 7272 from 7720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 10:
The number 808 fits into 4480 5 times, leaving a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 27119.95
If we take 4040 away from 4480, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
The number 808 fits into 4400 5 times, leaving a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 27119.955
The remainder is 360 after subtracting 4040 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 27119.955, and the remainder is 0.036.
