We look at the division of 15127226 by 221 
We want to figure out the number of times 15127226 can be divided by 221.

Step 1:
221 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 221

Going ahead to step 2:
15 divided by 221 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 221

Moving on to step 3:
151 divided by 221 is 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 151, we end up with 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 221

Let's proceed to step 4:
If we divide 1512 by 221, we get 6 and a remainder of 186.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 1326 from 1512 and we're left with 186.
Bring next digit (7) of the dividend behind the 186 and repeat the process: 1867 / 221

Going ahead to step 5:
When dividing 1867 by 221, we get 8 with a remainder of 99.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 1768 from 1867 leaves us with 99.
Append the next digit (2) from the dividend to 99 and continue with: 992 / 221

On to step 6:
If we divide 992 by 221, we get 4 and a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 684.0
Deduct 884 from 992 and we're left with 108.
Append the next digit (2) from the dividend to 108 and continue with: 1082 / 221

Let's proceed to step 7:
221 goes into 1082 4 times with a remainder of 198.
Record the quotient 4 as the next digit in the result. 
Result so far: 6844.0
Subtracting 884 from 1082 leaves us with 198.
Append the next digit (6) from the dividend to 198 and continue with: 1986 / 221

Moving on to step 8:
221 can be fit into 1986 8 times, resulting in a remainder of 218.
Write down 8 as next digit of the result. 
Result so far: 68448.0
Subtract 1768 from 1986 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
When dividing 2180 by 221, we get 9 with a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 68448.9
If we take 1989 away from 2180, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 10:
221 goes into 1910 8 times with a remainder of 142.
Use 8 as the next digit of our solution. 
Result so far: 68448.98
If we subtract 1768 from 1910, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 11:
When dividing 1420 by 221, we get 6 with a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 68448.986
Subtracting 1326 from 1420 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
When dividing 940 by 221, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 68448.9864
The remainder is 56 after subtracting 884 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
221 can be fit into 560 2 times, resulting in a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 68448.98642
If we subtract 442 from 560, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 14:
221 goes into 1180 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 68448.986425
The remainder is 75 after subtracting 1105 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 15:
When dividing 750 by 221, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 68448.9864253
If we take 663 away from 750, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 16:
If we divide 870 by 221, we get 3 and a remainder of 207.
The next digit of our result is 3. 
Result so far: 68448.98642533
Subtracting 663 from 870 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 68448.98642533 and a remainder of 2.07e-07.
