84890 ÷ 49 
Our goal is to divide 84890 by 49.

On to step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 49

Advancing to step 2:
49 can be fit into 84 1 times, resulting in a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 49 from 84 leaves us with 35.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 49

Step 3:
49 goes into 358 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 343 from 358 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 49

Step 4:
49 goes into 159 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 173.0
Subtracting 147 from 159 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 49

Going ahead to step 5:
120 divided by 49 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 1732.0
If we subtract 98 from 120, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 6:
220 divided by 49 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1732.4
If we take 196 away from 220, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 49 fits into 240 4 times, leaving a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 1732.44
Deduct 196 from 240 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 1732.44 and a remainder of 0.044.
