Let's divide 8564100 by 573
We're looking to find how many times 573 goes into 8564100.

Step 1:
The number 573 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 573

On to step 2:
When dividing 85 by 573, we get 0 with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Include the next digit (6) from the dividend after 85, then repeat: 856 / 573

Step 3:
573 can be fit into 856 1 times, resulting in a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 573 from 856 leaves us with 283.
Include the next digit (4) from the dividend after 283, then repeat: 2834 / 573

On to step 4:
2834 divided by 573 is 4 with a remainder of 542.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2292 from 2834 to get 542.
Grab the next digit (1) from the dividend, add it to 542, then carry on: 5421 / 573

Moving on to step 5:
573 goes into 5421 9 times with a remainder of 264.
Put 9 as the next digit of the answer. 
Result so far: 149.0
Subtract 5157 from 5421 to get 264.
Append the next digit (0) from the dividend to 264 and continue with: 2640 / 573

On to step 6:
573 goes into 2640 4 times with a remainder of 348.
The next digit of our result is 4. 
Result so far: 1494.0
If we subtract 2292 from 2640, we get 348.
Bring next digit (0) of the dividend behind the 348 and repeat the process: 3480 / 573

On to step 7:
573 can be fit into 3480 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 14946.0
If we subtract 3438 from 3480, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
When dividing 420 by 573, we get 0 with a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 14946.0
If we take 0 away from 420, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 9:
When dividing 4200 by 573, we get 7 with a remainder of 189.
Put 7 as the next digit of the answer. 
Result so far: 14946.07
If we subtract 4011 from 4200, 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.

Going ahead to step 10:
When dividing 1890 by 573, we get 3 with a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 14946.073
If we subtract 1719 from 1890, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 11:
The number 573 fits into 1710 2 times, leaving a remainder of 564.
The number 2 becomes the next digit in our result. 
Result so far: 14946.0732
If we subtract 1146 from 1710, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 12:
If we divide 5640 by 573, we get 9 and a remainder of 483.
Use 9 as the next digit of our solution. 
Result so far: 14946.07329
Subtract 5157 from 5640 to get 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Moving on to step 13:
573 goes into 4830 8 times with a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 14946.073298
Deduct 4584 from 4830 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 14:
The number 573 fits into 2460 4 times, leaving a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 14946.0732984
The remainder is 168 after subtracting 2292 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 15:
The number 573 fits into 1680 2 times, leaving a remainder of 534.
The next digit of our result is 2. 
Result so far: 14946.07329842
Subtract 1146 from 1680 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

After the division, we end up with 14946.07329842 and a remainder of 5.34e-07.
