91663776 ÷ 245 
We want to figure out the number of times 91663776 can be divided by 245.

On to step 1:
When dividing 9 by 245, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 245

Moving on to step 2:
If we divide 91 by 245, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 245

Let's proceed to step 3:
When dividing 916 by 245, we get 3 with a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 181 after subtracting 735 from 916.
Fetch the next digit (6) from the dividend, attach it to 181 and continue: 1816 / 245

Moving on to step 4:
The number 245 fits into 1816 7 times, leaving a remainder of 101.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 1715 from 1816, we get 101.
Fetch the next digit (3) from the dividend, attach it to 101 and continue: 1013 / 245

Advancing to step 5:
245 can be fit into 1013 4 times, resulting in a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 374.0
If we subtract 980 from 1013, we get 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 245

Moving on to step 6:
When dividing 337 by 245, we get 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 3741.0
If we subtract 245 from 337, we get 92.
Bring next digit (7) of the dividend behind the 92 and repeat the process: 927 / 245

Step 7:
When dividing 927 by 245, we get 3 with a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 37413.0
The remainder is 192 after subtracting 735 from 927.
Bring next digit (6) of the dividend behind the 192 and repeat the process: 1926 / 245

Going ahead to step 8:
1926 divided by 245 is 7 with a remainder of 211.
Write down 7 as next digit of the result. 
Result so far: 374137.0
Subtracting 1715 from 1926 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 9:
2110 divided by 245 is 8 with a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 374137.8
If we take 1960 away from 2110, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
When dividing 1500 by 245, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 374137.86
Deduct 1470 from 1500 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 245, we get 1 and a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 374137.861
Subtract 245 from 300 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
550 divided by 245 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 374137.8612
Deduct 490 from 550 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
When dividing 600 by 245, we get 2 with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 374137.86122
If we take 490 away from 600, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 374137.86122 with a remainder of 0.00011.
