We're dividing 80918099 by 221 
We want to figure out the number of times 80918099 can be divided by 221.

Step 1:
221 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 221

On to step 2:
221 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 221

Going ahead to step 3:
809 divided by 221 is 3 with a remainder of 146.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 663 from 809, we get 146.
Grab the next digit (1) from the dividend, add it to 146, then carry on: 1461 / 221

Let's proceed to step 4:
1461 divided by 221 is 6 with a remainder of 135.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 1326 from 1461 to get 135.
Append the next digit (8) from the dividend to 135 and continue with: 1358 / 221

Step 5:
221 goes into 1358 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 366.0
Subtract 1326 from 1358 to get 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 221

Going ahead to step 6:
The number 221 fits into 320 1 times, leaving a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 3661.0
Subtracting 221 from 320 leaves us with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 221

Step 7:
221 goes into 999 4 times with a remainder of 115.
Put 4 as the next digit of the answer. 
Result so far: 36614.0
The remainder is 115 after subtracting 884 from 999.
Take the next digit (9) from the dividend and append it to 115, then repeat: 1159 / 221

Moving on to step 8:
221 goes into 1159 5 times with a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 366145.0
The remainder is 54 after subtracting 1105 from 1159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
221 can be fit into 540 2 times, resulting in a remainder of 98.
Record the quotient 2 as the next digit in the result. 
Result so far: 366145.2
Subtract 442 from 540 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 10:
980 divided by 221 is 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 366145.24
If we subtract 884 from 980, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
When dividing 960 by 221, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 366145.244
Subtracting 884 from 960 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 366145.244 with a balance of 0.0076.
