We're dividing 233519 by 20 
We want to figure out the number of times 233519 can be divided by 20.

Moving on to step 1:
20 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 20

On to step 2:
20 goes into 23 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 20 from 23.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 20

Moving on to step 3:
20 can be fit into 33 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 20 from 33 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 20

Advancing to step 4:
20 can be fit into 135 6 times, resulting in a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 120 away from 135, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 20

Step 5:
20 can be fit into 151 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 1167.0
The remainder is 11 after subtracting 140 from 151.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 20

Advancing to step 6:
20 goes into 119 5 times with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 11675.0
If we subtract 100 from 119, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 11675.9
If we subtract 180 from 190, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11675.95
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11675.95
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11675.95
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 11675.95, and the remainder is 0.0.
