Fetch the next digit (5) from the dividend, attach it to 567 and continue: 5675 / 897

Moving on to step 5:
The number 897 fits into 5675 6 times, leaving a remainder of 293.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 5382 from 5675, we get 293.
Fetch the next digit (2) from the dividend, attach it to 293 and continue: 2932 / 897

Going ahead to step 6:
When dividing 2932 by 897, we get 3 with a remainder of 241.
Use 3 as the next digit of our solution. 
Result so far: 863.0
If we subtract 2691 from 2932, we get 241.
Take the next digit (2) from the dividend and append it to 241, then repeat: 2412 / 897

Advancing to step 7:
When dividing 2412 by 897, we get 2 with a remainder of 618.
The number 2 becomes the next digit in our result. 
Result so far: 8632.0
Deduct 1794 from 2412 and we're left with 618.
Bring next digit (2) of the dividend behind the 618 and repeat the process: 6182 / 897

Moving on to step 8:
897 can be fit into 6182 6 times, resulting in a remainder of 800.
Record the quotient 6 as the next digit in the result. 
Result so far: 86326.0
Deduct 5382 from 6182 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 9:
If we divide 8000 by 897, we get 8 and a remainder of 824.
Record the quotient 8 as the next digit in the result. 
Result so far: 86326.8
If we take 7176 away from 8000, we end up with 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

Moving on to step 10:
897 goes into 8240 9 times with a remainder of 167.
The next digit of our result is 9. 
Result so far: 86326.89
Deduct 8073 from 8240 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 11:
897 goes into 1670 1 times with a remainder of 773.
The number 1 becomes the next digit in our result. 
Result so far: 86326.891
If we take 897 away from 1670, we end up with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Let's proceed to step 12:
The number 897 fits into 7730 8 times, leaving a remainder of 554.
The number 8 becomes the next digit in our result. 
Result so far: 86326.8918
Deduct 7176 from 7730 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 13:
When dividing 5540 by 897, we get 6 with a remainder of 158.
The next digit of our result is 6. 
Result so far: 86326.89186
If we take 5382 away from 5540, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 14:
897 goes into 1580 1 times with a remainder of 683.
Use 1 as the next digit of our solution. 
Result so far: 86326.891861
Deduct 897 from 1580 and we're left with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Let's proceed to step 15:
6830 divided by 897 is 7 with a remainder of 551.
Put 7 as the next digit of the answer. 
Result so far: 86326.8918617
The remainder is 551 after subtracting 6279 from 6830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 16:
5510 divided by 897 is 6 with a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 86326.89186176
The remainder is 128 after subtracting 5382 from 5510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 86326.89186176 with a remainder of 1.28e-07.
