We're dividing 15646951 by 264 
We want to figure out the number of times 15646951 can be divided by 264.

Step 1:
When dividing 1 by 264, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 264

On to step 2:
The number 264 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 264

On to step 3:
When dividing 156 by 264, we get 0 with a remainder of 156.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 156, we get 156.
Fetch the next digit (4) from the dividend, attach it to 156 and continue: 1564 / 264

Going ahead to step 4:
264 goes into 1564 5 times with a remainder of 244.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 1320 from 1564 leaves us with 244.
Grab the next digit (6) from the dividend, add it to 244, then carry on: 2446 / 264

Going ahead to step 5:
264 goes into 2446 9 times with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Deduct 2376 from 2446 and we're left with 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 264

Going ahead to step 6:
The number 264 fits into 709 2 times, leaving a remainder of 181.
Use 2 as the next digit of our solution. 
Result so far: 592.0
Deduct 528 from 709 and we're left with 181.
Append the next digit (5) from the dividend to 181 and continue with: 1815 / 264

Moving on to step 7:
When dividing 1815 by 264, we get 6 with a remainder of 231.
The next digit of our result is 6. 
Result so far: 5926.0
Deduct 1584 from 1815 and we're left with 231.
Fetch the next digit (1) from the dividend, attach it to 231 and continue: 2311 / 264

Going ahead to step 8:
When dividing 2311 by 264, we get 8 with a remainder of 199.
The number 8 becomes the next digit in our result. 
Result so far: 59268.0
Subtracting 2112 from 2311 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 9:
When dividing 1990 by 264, we get 7 with a remainder of 142.
Record the quotient 7 as the next digit in the result. 
Result so far: 59268.7
If we subtract 1848 from 1990, 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.

Let's proceed to step 10:
264 goes into 1420 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 59268.75
The remainder is 100 after subtracting 1320 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
264 can be fit into 1000 3 times, resulting in a remainder of 208.
Put 3 as the next digit of the answer. 
Result so far: 59268.753
If we take 792 away from 1000, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
If we divide 2080 by 264, we get 7 and a remainder of 232.
The next digit of our result is 7. 
Result so far: 59268.7537
The remainder is 232 after subtracting 1848 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 13:
The number 264 fits into 2320 8 times, leaving a remainder of 208.
The next digit of our result is 8. 
Result so far: 59268.75378
If we subtract 2112 from 2320, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 14:
2080 divided by 264 is 7 with a remainder of 232.
Write down 7 as next digit of the result. 
Result so far: 59268.753787
If we subtract 1848 from 2080, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 15:
2320 divided by 264 is 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 59268.7537878
If we subtract 2112 from 2320, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 16:
When dividing 2080 by 264, we get 7 with a remainder of 232.
The next digit of our result is 7. 
Result so far: 59268.75378787
If we subtract 1848 from 2080, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The quotient of the division is 59268.75378787, and the remainder is 2.32e-07.
