91164065 ÷ 261 
We're looking to find how many times 261 goes into 91164065.

Moving on to step 1:
9 divided by 261 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 261

On to step 2:
261 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 261

On to step 3:
If we divide 911 by 261, we get 3 and a remainder of 128.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 783 from 911 to get 128.
Bring next digit (6) of the dividend behind the 128 and repeat the process: 1286 / 261

Let's proceed to step 4:
If we divide 1286 by 261, we get 4 and a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 1044 from 1286, we get 242.
Include the next digit (4) from the dividend after 242, then repeat: 2424 / 261

Step 5:
261 can be fit into 2424 9 times, resulting in a remainder of 75.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
Subtracting 2349 from 2424 leaves us with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 261

Advancing to step 6:
The number 261 fits into 750 2 times, leaving a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 3492.0
If we subtract 522 from 750, we get 228.
Append the next digit (6) from the dividend to 228 and continue with: 2286 / 261

Step 7:
The number 261 fits into 2286 8 times, leaving a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 34928.0
Subtract 2088 from 2286 to get 198.
Include the next digit (5) from the dividend after 198, then repeat: 1985 / 261

Step 8:
The number 261 fits into 1985 7 times, leaving a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 349287.0
If we subtract 1827 from 1985, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
If we divide 1580 by 261, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 349287.6
If we take 1566 away from 1580, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 261, we get 0 and a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 349287.6
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
When dividing 1400 by 261, we get 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 349287.605
Subtracting 1305 from 1400 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 12:
261 goes into 950 3 times with a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 349287.6053
If we take 783 away from 950, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 13:
261 goes into 1670 6 times with a remainder of 104.
The next digit of our result is 6. 
Result so far: 349287.60536
If we subtract 1566 from 1670, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 14:
261 can be fit into 1040 3 times, resulting in a remainder of 257.
The next digit of our result is 3. 
Result so far: 349287.605363
Subtracting 783 from 1040 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 15:
If we divide 2570 by 261, we get 9 and a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 349287.6053639
Subtracting 2349 from 2570 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 16:
If we divide 2210 by 261, we get 8 and a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 349287.60536398
If we take 2088 away from 2210, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

In conclusion, the division gives 349287.60536398 with a balance of 1.22e-07.
