99639223 ÷ 221 
We're looking to find how many times 221 goes into 99639223.

Advancing to step 1:
If we divide 9 by 221, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 221

Moving on to step 2:
If we divide 99 by 221, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 221

Let's proceed to step 3:
The number 221 fits into 996 4 times, leaving a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 884 from 996 leaves us with 112.
Include the next digit (3) from the dividend after 112, then repeat: 1123 / 221

Step 4:
1123 divided by 221 is 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 1105 from 1123 and we're left with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 221

Advancing to step 5:
The number 221 fits into 189 0 times, leaving a remainder of 189.
Record the quotient 0 as the next digit in the result. 
Result so far: 450.0
If we take 0 away from 189, we end up with 189.
Fetch the next digit (2) from the dividend, attach it to 189 and continue: 1892 / 221

Advancing to step 6:
1892 divided by 221 is 8 with a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 4508.0
Subtract 1768 from 1892 to get 124.
Fetch the next digit (2) from the dividend, attach it to 124 and continue: 1242 / 221

Let's proceed to step 7:
The number 221 fits into 1242 5 times, leaving a remainder of 137.
Use 5 as the next digit of our solution. 
Result so far: 45085.0
Subtracting 1105 from 1242 leaves us with 137.
Grab the next digit (3) from the dividend, add it to 137, then carry on: 1373 / 221

Going ahead to step 8:
221 can be fit into 1373 6 times, resulting in a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 450856.0
Subtract 1326 from 1373 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
When dividing 470 by 221, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 450856.2
If we subtract 442 from 470, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
221 goes into 280 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 450856.21
Subtract 221 from 280 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 11:
221 can be fit into 590 2 times, resulting in a remainder of 148.
The next digit of our result is 2. 
Result so far: 450856.212
If we subtract 442 from 590, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 12:
If we divide 1480 by 221, we get 6 and a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 450856.2126
Deduct 1326 from 1480 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 13:
The number 221 fits into 1540 6 times, leaving a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 450856.21266
Deduct 1326 from 1540 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

In conclusion, the division gives 450856.21266 with a balance of 0.000214.
