80808331 ÷ 221 
We want to divide 80808331 by 221.

Going ahead to step 1:
If we divide 8 by 221, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 221

Step 2:
221 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (8) of the dividend behind the 80 and repeat the process: 808 / 221

On to step 3:
221 goes into 808 3 times with a remainder of 145.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 663 from 808 and we're left with 145.
Take the next digit (0) from the dividend and append it to 145, then repeat: 1450 / 221

Let's proceed to step 4:
If we divide 1450 by 221, we get 6 and a remainder of 124.
The next digit of our result is 6. 
Result so far: 36.0
Subtracting 1326 from 1450 leaves us with 124.
Fetch the next digit (8) from the dividend, attach it to 124 and continue: 1248 / 221

Moving on to step 5:
If we divide 1248 by 221, we get 5 and a remainder of 143.
The next digit of our result is 5. 
Result so far: 365.0
The remainder is 143 after subtracting 1105 from 1248.
Bring next digit (3) of the dividend behind the 143 and repeat the process: 1433 / 221

Let's proceed to step 6:
1433 divided by 221 is 6 with a remainder of 107.
The number 6 becomes the next digit in our result. 
Result so far: 3656.0
Subtracting 1326 from 1433 leaves us with 107.
Fetch the next digit (3) from the dividend, attach it to 107 and continue: 1073 / 221

On to step 7:
1073 divided by 221 is 4 with a remainder of 189.
Put 4 as the next digit of the answer. 
Result so far: 36564.0
Deduct 884 from 1073 and we're left with 189.
Fetch the next digit (1) from the dividend, attach it to 189 and continue: 1891 / 221

Let's proceed to step 8:
The number 221 fits into 1891 8 times, leaving a remainder of 123.
The number 8 becomes the next digit in our result. 
Result so far: 365648.0
If we subtract 1768 from 1891, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 9:
221 can be fit into 1230 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 365648.5
If we subtract 1105 from 1230, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
221 goes into 1250 5 times with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 365648.55
The remainder is 145 after subtracting 1105 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The quotient of the division is 365648.55, and the remainder is 0.145.
