99419315 ÷ 221 
Our goal is to divide 99419315 by 221.

Going ahead to step 1:
The number 221 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 221

Moving on to step 2:
The number 221 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 221

On to step 3:
221 can be fit into 994 4 times, resulting in a remainder of 110.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 884 away from 994, we end up with 110.
Bring next digit (1) of the dividend behind the 110 and repeat the process: 1101 / 221

Going ahead to step 4:
1101 divided by 221 is 4 with a remainder of 217.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 884 from 1101 to get 217.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 221

Let's proceed to step 5:
2179 divided by 221 is 9 with a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 449.0
If we take 1989 away from 2179, we end up with 190.
Append the next digit (3) from the dividend to 190 and continue with: 1903 / 221

Moving on to step 6:
If we divide 1903 by 221, we get 8 and a remainder of 135.
The number 8 becomes the next digit in our result. 
Result so far: 4498.0
The remainder is 135 after subtracting 1768 from 1903.
Include the next digit (1) from the dividend after 135, then repeat: 1351 / 221

Moving on to step 7:
If we divide 1351 by 221, we get 6 and a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 44986.0
Deduct 1326 from 1351 and we're left with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 221

Going ahead to step 8:
The number 221 fits into 255 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 449861.0
Deduct 221 from 255 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
When dividing 340 by 221, we get 1 with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 449861.1
Deduct 221 from 340 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 10:
221 goes into 1190 5 times with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 449861.15
Subtracting 1105 from 1190 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
When dividing 850 by 221, we get 3 with a remainder of 187.
Write down 3 as next digit of the result. 
Result so far: 449861.153
Deduct 663 from 850 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 12:
221 goes into 1870 8 times with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 449861.1538
Deduct 1768 from 1870 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 13:
If we divide 1020 by 221, we get 4 and a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 449861.15384
If we take 884 away from 1020, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 14:
1360 divided by 221 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 449861.153846
Subtract 1326 from 1360 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
When dividing 340 by 221, we get 1 with a remainder of 119.
The next digit of our result is 1. 
Result so far: 449861.1538461
Deduct 221 from 340 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 16:
221 goes into 1190 5 times with a remainder of 85.
The next digit of our result is 5. 
Result so far: 449861.15384615
Subtracting 1105 from 1190 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final result is 449861.15384615 with a remainder of 8.5e-08.
