We're dividing 20913485 by 235 
We want to figure out the number of times 20913485 can be divided by 235.

Step 1:
235 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
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 / 235

Let's proceed to step 2:
235 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 235

Advancing to step 3:
When dividing 209 by 235, we get 0 with a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Bring next digit (1) of the dividend behind the 209 and repeat the process: 2091 / 235

Advancing to step 4:
2091 divided by 235 is 8 with a remainder of 211.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 1880 from 2091 to get 211.
Fetch the next digit (3) from the dividend, attach it to 211 and continue: 2113 / 235

On to step 5:
2113 divided by 235 is 8 with a remainder of 233.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 1880 from 2113 leaves us with 233.
Include the next digit (4) from the dividend after 233, then repeat: 2334 / 235

Going ahead to step 6:
2334 divided by 235 is 9 with a remainder of 219.
Put 9 as the next digit of the answer. 
Result so far: 889.0
If we subtract 2115 from 2334, we get 219.
Take the next digit (8) from the dividend and append it to 219, then repeat: 2198 / 235

Moving on to step 7:
When dividing 2198 by 235, we get 9 with a remainder of 83.
Use 9 as the next digit of our solution. 
Result so far: 8899.0
Subtracting 2115 from 2198 leaves us with 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 235

Going ahead to step 8:
If we divide 835 by 235, we get 3 and a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 88993.0
Subtract 705 from 835 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 9:
The number 235 fits into 1300 5 times, leaving a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 88993.5
If we subtract 1175 from 1300, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
235 can be fit into 1250 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 88993.55
Subtracting 1175 from 1250 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 88993.55 with a remaining 0.075.
