Going ahead to step 5:
2698 divided by 587 is 4 with a remainder of 350.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 2348 from 2698 to get 350.
Include the next digit (9) from the dividend after 350, then repeat: 3509 / 587

On to step 6:
3509 divided by 587 is 5 with a remainder of 574.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
Deduct 2935 from 3509 and we're left with 574.
Fetch the next digit (9) from the dividend, attach it to 574 and continue: 5749 / 587

Going ahead to step 7:
587 can be fit into 5749 9 times, resulting in a remainder of 466.
Write down 9 as next digit of the result. 
Result so far: 3459.0
Subtract 5283 from 5749 to get 466.
Append the next digit (5) from the dividend to 466 and continue with: 4665 / 587

Advancing to step 8:
587 can be fit into 4665 7 times, resulting in a remainder of 556.
Write down 7 as next digit of the result. 
Result so far: 34597.0
The remainder is 556 after subtracting 4109 from 4665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 9:
The number 587 fits into 5560 9 times, leaving a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 34597.9
Subtract 5283 from 5560 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Moving on to step 10:
587 goes into 2770 4 times with a remainder of 422.
The number 4 becomes the next digit in our result. 
Result so far: 34597.94
The remainder is 422 after subtracting 2348 from 2770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 11:
587 goes into 4220 7 times with a remainder of 111.
Put 7 as the next digit of the answer. 
Result so far: 34597.947
Subtracting 4109 from 4220 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 12:
1110 divided by 587 is 1 with a remainder of 523.
Write down 1 as next digit of the result. 
Result so far: 34597.9471
Subtracting 587 from 1110 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 13:
587 goes into 5230 8 times with a remainder of 534.
Write down 8 as next digit of the result. 
Result so far: 34597.94718
The remainder is 534 after subtracting 4696 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 14:
587 can be fit into 5340 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 34597.947189
Subtract 5283 from 5340 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 15:
When dividing 570 by 587, we get 0 with a remainder of 570.
Use 0 as the next digit of our solution. 
Result so far: 34597.947189
Deduct 0 from 570 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 16:
587 goes into 5700 9 times with a remainder of 417.
The number 9 becomes the next digit in our result. 
Result so far: 34597.94718909
Subtracting 5283 from 5700 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

The quotient of the division is 34597.94718909, and the remainder is 4.17e-07.
