278135 ÷ 20 
We're looking to find how many times 20 goes into 278135.

On to step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 20

On to step 2:
If we divide 27 by 20, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 20 from 27 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Advancing to step 3:
When dividing 78 by 20, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 60 from 78 to get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 20

On to step 4:
181 divided by 20 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 139.0
Deduct 180 from 181 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 20

Advancing to step 5:
When dividing 13 by 20, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 1390.0
If we take 0 away from 13, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 20

Advancing to step 6:
135 divided by 20 is 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 13906.0
If we take 120 away from 135, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
150 divided by 20 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 13906.7
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13906.75
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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13906.75
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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 13906.75
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.

The quotient of the division is 13906.75, and the remainder is 0.0.
