Moving on to step 5:
When dividing 5539 by 858, we get 6 with a remainder of 391.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Deduct 5148 from 5539 and we're left with 391.
Include the next digit (1) from the dividend after 391, then repeat: 3911 / 858

Moving on to step 6:
858 goes into 3911 4 times with a remainder of 479.
Use 4 as the next digit of our solution. 
Result so far: 1164.0
If we subtract 3432 from 3911, we get 479.
Fetch the next digit (1) from the dividend, attach it to 479 and continue: 4791 / 858

Moving on to step 7:
If we divide 4791 by 858, we get 5 and a remainder of 501.
Record the quotient 5 as the next digit in the result. 
Result so far: 11645.0
Subtract 4290 from 4791 to get 501.
Grab the next digit (1) from the dividend, add it to 501, then carry on: 5011 / 858

Going ahead to step 8:
The number 858 fits into 5011 5 times, leaving a remainder of 721.
Write down 5 as next digit of the result. 
Result so far: 116455.0
Deduct 4290 from 5011 and we're left with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

On to step 9:
When dividing 7210 by 858, we get 8 with a remainder of 346.
The number 8 becomes the next digit in our result. 
Result so far: 116455.8
Deduct 6864 from 7210 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 10:
When dividing 3460 by 858, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 116455.84
Subtract 3432 from 3460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 858 fits into 280 0 times, leaving a remainder of 280.
The next digit of our result is 0. 
Result so far: 116455.84
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
2800 divided by 858 is 3 with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 116455.8403
If we subtract 2574 from 2800, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 13:
858 can be fit into 2260 2 times, resulting in a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 116455.84032
Subtract 1716 from 2260 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 14:
858 can be fit into 5440 6 times, resulting in a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 116455.840326
The remainder is 292 after subtracting 5148 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 15:
858 can be fit into 2920 3 times, resulting in a remainder of 346.
Put 3 as the next digit of the answer. 
Result so far: 116455.8403263
If we take 2574 away from 2920, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 16:
The number 858 fits into 3460 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 116455.84032634
Subtract 3432 from 3460 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 116455.84032634 with a remaining 2.8e-08.
