Let's divide 78105921 by 264
We want to figure out the number of times 78105921 can be divided by 264.

Step 1:
264 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 264

Moving on to step 2:
The number 264 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 264

Step 3:
264 can be fit into 781 2 times, resulting in a remainder of 253.
The next digit of our result is 2. 
Result so far: 2.0
If we take 528 away from 781, we end up with 253.
Take the next digit (0) from the dividend and append it to 253, then repeat: 2530 / 264

On to step 4:
264 can be fit into 2530 9 times, resulting in a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 2376 away from 2530, we end up with 154.
Grab the next digit (5) from the dividend, add it to 154, then carry on: 1545 / 264

Going ahead to step 5:
If we divide 1545 by 264, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 295.0
If we subtract 1320 from 1545, we get 225.
Append the next digit (9) from the dividend to 225 and continue with: 2259 / 264

On to step 6:
The number 264 fits into 2259 8 times, leaving a remainder of 147.
Record the quotient 8 as the next digit in the result. 
Result so far: 2958.0
Subtracting 2112 from 2259 leaves us with 147.
Append the next digit (2) from the dividend to 147 and continue with: 1472 / 264

Let's proceed to step 7:
The number 264 fits into 1472 5 times, leaving a remainder of 152.
The next digit of our result is 5. 
Result so far: 29585.0
Deduct 1320 from 1472 and we're left with 152.
Fetch the next digit (1) from the dividend, attach it to 152 and continue: 1521 / 264

Going ahead to step 8:
264 goes into 1521 5 times with a remainder of 201.
Write down 5 as next digit of the result. 
Result so far: 295855.0
If we subtract 1320 from 1521, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 9:
When dividing 2010 by 264, we get 7 with a remainder of 162.
The next digit of our result is 7. 
Result so far: 295855.7
Subtract 1848 from 2010 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 10:
264 goes into 1620 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 295855.76
If we subtract 1584 from 1620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
264 can be fit into 360 1 times, resulting in a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 295855.761
If we take 264 away from 360, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
264 can be fit into 960 3 times, resulting in a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 295855.7613
Subtract 792 from 960 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
The number 264 fits into 1680 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 295855.76136
Subtracting 1584 from 1680 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
264 goes into 960 3 times with a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 295855.761363
The remainder is 168 after subtracting 792 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 15:
264 goes into 1680 6 times with a remainder of 96.
The next digit of our result is 6. 
Result so far: 295855.7613636
Subtracting 1584 from 1680 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 16:
960 divided by 264 is 3 with a remainder of 168.
Record the quotient 3 as the next digit in the result. 
Result so far: 295855.76136363
Deduct 792 from 960 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 295855.76136363 and a remainder of 1.68e-07.
