269790 ÷ 20 
We want to figure out the number of times 269790 can be divided by 20.

Step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 20

Advancing to step 2:
If we divide 26 by 20, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 6 after subtracting 20 from 26.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 20

Advancing to step 3:
The number 20 fits into 69 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 60 from 69 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 20

Let's proceed to step 4:
97 divided by 20 is 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 134.0
The remainder is 17 after subtracting 80 from 97.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 20

Advancing to step 5:
If we divide 179 by 20, we get 8 and a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 1348.0
If we take 160 away from 179, we end up with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 20

On to step 6:
When dividing 190 by 20, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 13489.0
Subtracting 180 from 190 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
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: 13489.5
Subtracting 100 from 100 leaves us 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 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13489.5
Deduct 0 from 0 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.
The next digit of our result is 0. 
Result so far: 13489.5
Subtract 0 from 0 to 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 13489.5, and the remainder is 0.0.
