Let's divide 86487297 by 575
We want to figure out the number of times 86487297 can be divided by 575.

Step 1:
8 divided by 575 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 575

On to step 2:
86 divided by 575 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 575

Let's proceed to step 3:
If we divide 864 by 575, we get 1 and a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 575 away from 864, we end up with 289.
Bring next digit (8) of the dividend behind the 289 and repeat the process: 2898 / 575

Let's proceed to step 4:
The number 575 fits into 2898 5 times, leaving a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 2875 from 2898 and we're left with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 575

Moving on to step 5:
The number 575 fits into 237 0 times, leaving a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Subtract 0 from 237 to get 237.
Append the next digit (2) from the dividend to 237 and continue with: 2372 / 575

Step 6:
575 goes into 2372 4 times with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 1504.0
If we take 2300 away from 2372, we end up with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 575

On to step 7:
If we divide 729 by 575, we get 1 and a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 15041.0
If we subtract 575 from 729, we get 154.
Fetch the next digit (7) from the dividend, attach it to 154 and continue: 1547 / 575

On to step 8:
The number 575 fits into 1547 2 times, leaving a remainder of 397.
Use 2 as the next digit of our solution. 
Result so far: 150412.0
The remainder is 397 after subtracting 1150 from 1547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 9:
575 goes into 3970 6 times with a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 150412.6
Subtract 3450 from 3970 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
When dividing 5200 by 575, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 150412.69
If we take 5175 away from 5200, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
575 can be fit into 250 0 times, resulting in a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 150412.69
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
The number 575 fits into 2500 4 times, leaving a remainder of 200.
The next digit of our result is 4. 
Result so far: 150412.6904
Subtract 2300 from 2500 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
When dividing 2000 by 575, we get 3 with a remainder of 275.
Record the quotient 3 as the next digit in the result. 
Result so far: 150412.69043
Deduct 1725 from 2000 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 14:
If we divide 2750 by 575, we get 4 and a remainder of 450.
The number 4 becomes the next digit in our result. 
Result so far: 150412.690434
Subtracting 2300 from 2750 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
When dividing 4500 by 575, we get 7 with a remainder of 475.
Use 7 as the next digit of our solution. 
Result so far: 150412.6904347
Subtract 4025 from 4500 to get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 16:
575 goes into 4750 8 times with a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 150412.69043478
If we subtract 4600 from 4750, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 150412.69043478 with a remainder of 1.5e-07.
