On to step 3:
If we divide 534 by 585, we get 0 and a remainder of 534.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 534 to get 534.
Bring next digit (0) of the dividend behind the 534 and repeat the process: 5340 / 585

Moving on to step 4:
585 goes into 5340 9 times with a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 5265 from 5340 leaves us with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 585

Advancing to step 5:
754 divided by 585 is 1 with a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 91.0
The remainder is 169 after subtracting 585 from 754.
Bring next digit (2) of the dividend behind the 169 and repeat the process: 1692 / 585

Step 6:
The number 585 fits into 1692 2 times, leaving a remainder of 522.
Use 2 as the next digit of our solution. 
Result so far: 912.0
The remainder is 522 after subtracting 1170 from 1692.
Include the next digit (3) from the dividend after 522, then repeat: 5223 / 585

Advancing to step 7:
5223 divided by 585 is 8 with a remainder of 543.
Put 8 as the next digit of the answer. 
Result so far: 9128.0
Subtract 4680 from 5223 to get 543.
Include the next digit (7) from the dividend after 543, then repeat: 5437 / 585

On to step 8:
The number 585 fits into 5437 9 times, leaving a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 91289.0
Deduct 5265 from 5437 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 9:
When dividing 1720 by 585, we get 2 with a remainder of 550.
The number 2 becomes the next digit in our result. 
Result so far: 91289.2
Deduct 1170 from 1720 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 10:
585 can be fit into 5500 9 times, resulting in a remainder of 235.
The next digit of our result is 9. 
Result so far: 91289.29
The remainder is 235 after subtracting 5265 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 11:
When dividing 2350 by 585, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 91289.294
Subtract 2340 from 2350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 585, we get 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 91289.294
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
585 goes into 1000 1 times with a remainder of 415.
The number 1 becomes the next digit in our result. 
Result so far: 91289.29401
Subtract 585 from 1000 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 14:
The number 585 fits into 4150 7 times, leaving a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 91289.294017
The remainder is 55 after subtracting 4095 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 15:
The number 585 fits into 550 0 times, leaving a remainder of 550.
Use 0 as the next digit of our solution. 
Result so far: 91289.294017
If we subtract 0 from 550, 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.

Step 16:
The number 585 fits into 5500 9 times, leaving a remainder of 235.
Put 9 as the next digit of the answer. 
Result so far: 91289.29401709
If we subtract 5265 from 5500, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

In conclusion, the division gives 91289.29401709 with a balance of 2.35e-07.
