We look at the division of 853589 by 17 
We want to figure out the number of times 853589 can be divided by 17.

Advancing to step 1:
The number 17 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 17

Step 2:
17 goes into 85 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 85 from 85 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 17

Step 3:
3 divided by 17 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 17

Going ahead to step 4:
17 goes into 35 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 502.0
If we subtract 34 from 35, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 17

On to step 5:
If we divide 18 by 17, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 5021.0
Subtracting 17 from 18 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 17

Moving on to step 6:
When dividing 19 by 17, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 50211.0
If we take 17 away from 19, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
17 goes into 20 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 50211.1
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
When dividing 30 by 17, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 50211.11
Subtracting 17 from 30 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 50211.11 and a remainder of 0.013.
