We're dividing 561020 by 18 
We're looking to find how many times 18 goes into 561020.

Step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 18

Going ahead to step 2:
18 goes into 56 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 54 from 56 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 18

Advancing to step 3:
18 can be fit into 21 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 18 away from 21, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 18

On to step 4:
If we divide 30 by 18, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 311.0
Subtracting 18 from 30 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 18

Step 5:
18 can be fit into 122 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 3116.0
If we take 108 away from 122, we end up with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 18

Moving on to step 6:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 31167.0
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
18 goes into 140 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 31167.7
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 18, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 31167.77
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 31167.77 with a remaining 0.014.
