15150864 ÷ 575 
We want to figure out the number of times 15150864 can be divided by 575.

Going ahead to step 1:
The number 575 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 575

Step 2:
When dividing 15 by 575, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 575

On to step 3:
If we divide 151 by 575, we get 0 and a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Take the next digit (5) from the dividend and append it to 151, then repeat: 1515 / 575

Moving on to step 4:
If we divide 1515 by 575, we get 2 and a remainder of 365.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1150 away from 1515, we end up with 365.
Bring next digit (0) of the dividend behind the 365 and repeat the process: 3650 / 575

On to step 5:
When dividing 3650 by 575, we get 6 with a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 3450 from 3650 leaves us with 200.
Bring next digit (8) of the dividend behind the 200 and repeat the process: 2008 / 575

Going ahead to step 6:
575 goes into 2008 3 times with a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
If we subtract 1725 from 2008, we get 283.
Include the next digit (6) from the dividend after 283, then repeat: 2836 / 575

Let's proceed to step 7:
575 can be fit into 2836 4 times, resulting in a remainder of 536.
The number 4 becomes the next digit in our result. 
Result so far: 2634.0
If we subtract 2300 from 2836, we get 536.
Take the next digit (4) from the dividend and append it to 536, then repeat: 5364 / 575

Let's proceed to step 8:
If we divide 5364 by 575, we get 9 and a remainder of 189.
The number 9 becomes the next digit in our result. 
Result so far: 26349.0
If we subtract 5175 from 5364, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
When dividing 1890 by 575, we get 3 with a remainder of 165.
Put 3 as the next digit of the answer. 
Result so far: 26349.3
Subtract 1725 from 1890 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
1650 divided by 575 is 2 with a remainder of 500.
The next digit of our result is 2. 
Result so far: 26349.32
If we take 1150 away from 1650, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
575 goes into 5000 8 times with a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 26349.328
Deduct 4600 from 5000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
The number 575 fits into 4000 6 times, leaving a remainder of 550.
The number 6 becomes the next digit in our result. 
Result so far: 26349.3286
If we subtract 3450 from 4000, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 13:
575 goes into 5500 9 times with a remainder of 325.
The next digit of our result is 9. 
Result so far: 26349.32869
Subtracting 5175 from 5500 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 14:
When dividing 3250 by 575, we get 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 26349.328695
If we subtract 2875 from 3250, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Going ahead to step 15:
575 goes into 3750 6 times with a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 26349.3286956
Subtract 3450 from 3750 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
575 goes into 3000 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 26349.32869565
If we take 2875 away from 3000, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 26349.32869565 and a remainder of 1.25e-07.
