91309652 ÷ 221 
We want to figure out the number of times 91309652 can be divided by 221.

Advancing to step 1:
When dividing 9 by 221, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 221

Advancing to step 2:
221 can be fit into 91 0 times, resulting in a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 221

Step 3:
913 divided by 221 is 4 with a remainder of 29.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 884 from 913 to get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 221

Let's proceed to step 4:
When dividing 290 by 221, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 221 away from 290, we end up with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 221

Let's proceed to step 5:
The number 221 fits into 699 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 413.0
Subtracting 663 from 699 leaves us with 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 221

On to step 6:
221 goes into 366 1 times with a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 4131.0
If we subtract 221 from 366, we get 145.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 221

Going ahead to step 7:
If we divide 1455 by 221, we get 6 and a remainder of 129.
Record the quotient 6 as the next digit in the result. 
Result so far: 41316.0
The remainder is 129 after subtracting 1326 from 1455.
Bring next digit (2) of the dividend behind the 129 and repeat the process: 1292 / 221

On to step 8:
When dividing 1292 by 221, we get 5 with a remainder of 187.
The next digit of our result is 5. 
Result so far: 413165.0
Subtracting 1105 from 1292 leaves us 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.

Going ahead to step 9:
1870 divided by 221 is 8 with a remainder of 102.
The next digit of our result is 8. 
Result so far: 413165.8
If we subtract 1768 from 1870, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
1020 divided by 221 is 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 413165.84
If we subtract 884 from 1020, we get 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 11:
When dividing 1360 by 221, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 413165.846
Subtracting 1326 from 1360 leaves us 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.

Step 12:
340 divided by 221 is 1 with a remainder of 119.
Use 1 as the next digit of our solution. 
Result so far: 413165.8461
If we take 221 away from 340, we end up 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 13:
When dividing 1190 by 221, we get 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 413165.84615
Subtract 1105 from 1190 to get 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 14:
221 goes into 850 3 times with a remainder of 187.
The next digit of our result is 3. 
Result so far: 413165.846153
Subtract 663 from 850 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 15:
When dividing 1870 by 221, we get 8 with a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 413165.8461538
Subtract 1768 from 1870 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 16:
221 can be fit into 1020 4 times, resulting in a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 413165.84615384
Subtracting 884 from 1020 leaves us 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.

The final result is 413165.84615384 with a remainder of 1.36e-07.
