We're dividing 20355590 by 935 
We want to figure out the number of times 20355590 can be divided by 935.

Advancing to step 1:
The number 935 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 935

Let's proceed to step 2:
The number 935 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 935

Let's proceed to step 3:
If we divide 203 by 935, we get 0 and a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 203, we get 203.
Append the next digit (5) from the dividend to 203 and continue with: 2035 / 935

Going ahead to step 4:
The number 935 fits into 2035 2 times, leaving a remainder of 165.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1870 from 2035 leaves us with 165.
Fetch the next digit (5) from the dividend, attach it to 165 and continue: 1655 / 935

Moving on to step 5:
When dividing 1655 by 935, we get 1 with a remainder of 720.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 935 from 1655 and we're left with 720.
Grab the next digit (5) from the dividend, add it to 720, then carry on: 7205 / 935

On to step 6:
If we divide 7205 by 935, we get 7 and a remainder of 660.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
The remainder is 660 after subtracting 6545 from 7205.
Include the next digit (9) from the dividend after 660, then repeat: 6609 / 935

Advancing to step 7:
6609 divided by 935 is 7 with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 2177.0
If we take 6545 away from 6609, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 935

On to step 8:
The number 935 fits into 640 0 times, leaving a remainder of 640.
Use 0 as the next digit of our solution. 
Result so far: 21770.0
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 9:
935 goes into 6400 6 times with a remainder of 790.
The number 6 becomes the next digit in our result. 
Result so far: 21770.6
The remainder is 790 after subtracting 5610 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 10:
935 goes into 7900 8 times with a remainder of 420.
The number 8 becomes the next digit in our result. 
Result so far: 21770.68
Deduct 7480 from 7900 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 11:
The number 935 fits into 4200 4 times, leaving a remainder of 460.
Record the quotient 4 as the next digit in the result. 
Result so far: 21770.684
If we subtract 3740 from 4200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
The number 935 fits into 4600 4 times, leaving a remainder of 860.
The next digit of our result is 4. 
Result so far: 21770.6844
Subtracting 3740 from 4600 leaves us with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final outcome is 21770.6844, with a leftover of 0.0086.
