When dividing 2559 by 858, we get 2 with a remainder of 843.
Write down 2 as next digit of the result. 
Result so far: 532.0
Subtracting 1716 from 2559 leaves us with 843.
Grab the next digit (5) from the dividend, add it to 843, then carry on: 8435 / 858

On to step 7:
8435 divided by 858 is 9 with a remainder of 713.
Write down 9 as next digit of the result. 
Result so far: 5329.0
The remainder is 713 after subtracting 7722 from 8435.
Append the next digit (3) from the dividend to 713 and continue with: 7133 / 858

Let's proceed to step 8:
If we divide 7133 by 858, we get 8 and a remainder of 269.
Write down 8 as next digit of the result. 
Result so far: 53298.0
Deduct 6864 from 7133 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
858 goes into 2690 3 times with a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 53298.3
If we take 2574 away from 2690, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
858 can be fit into 1160 1 times, resulting in a remainder of 302.
Use 1 as the next digit of our solution. 
Result so far: 53298.31
Subtract 858 from 1160 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 11:
858 can be fit into 3020 3 times, resulting in a remainder of 446.
The number 3 becomes the next digit in our result. 
Result so far: 53298.313
If we take 2574 away from 3020, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 12:
The number 858 fits into 4460 5 times, leaving a remainder of 170.
The next digit of our result is 5. 
Result so far: 53298.3135
If we take 4290 away from 4460, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
858 goes into 1700 1 times with a remainder of 842.
Write down 1 as next digit of the result. 
Result so far: 53298.31351
If we subtract 858 from 1700, we get 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Let's proceed to step 14:
When dividing 8420 by 858, we get 9 with a remainder of 698.
Use 9 as the next digit of our solution. 
Result so far: 53298.313519
Subtracting 7722 from 8420 leaves us with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Moving on to step 15:
The number 858 fits into 6980 8 times, leaving a remainder of 116.
The next digit of our result is 8. 
Result so far: 53298.3135198
If we take 6864 away from 6980, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 16:
If we divide 1160 by 858, we get 1 and a remainder of 302.
The next digit of our result is 1. 
Result so far: 53298.31351981
Subtracting 858 from 1160 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

After the division, we end up with 53298.31351981 and a remainder of 3.02e-07.
