208570 ÷ 90 
We're looking to find how many times 90 goes into 208570.

Advancing to step 1:
If we divide 2 by 90, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 90

On to step 2:
90 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 90

Step 3:
90 can be fit into 208 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 180 from 208 and we're left with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 90

Let's proceed to step 4:
90 can be fit into 285 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 270 from 285, we get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 90

Going ahead to step 5:
90 can be fit into 157 1 times, resulting in a remainder of 67.
The next digit of our result is 1. 
Result so far: 231.0
Subtract 90 from 157 to get 67.
Append the next digit (0) from the dividend to 67 and continue with: 670 / 90

Going ahead to step 6:
The number 90 fits into 670 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 2317.0
Deduct 630 from 670 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
If we divide 400 by 90, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 2317.4
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 2317.44
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 2317.44 with a remaining 0.04.
