We're dividing 21559 by 67 
Let's see how many times 67 fits into 21559.

Going ahead to step 1:
67 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 67

Advancing to step 2:
67 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 67

Let's proceed to step 3:
The number 67 fits into 215 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 201 from 215 leaves us with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 67

On to step 4:
67 can be fit into 145 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 134 from 145 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 67

Going ahead to step 5:
119 divided by 67 is 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 321.0
Deduct 67 from 119 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 6:
520 divided by 67 is 7 with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 321.7
Deduct 469 from 520 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 67, we get 7 and a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 321.77
Subtract 469 from 510 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The quotient of the division is 321.77, and the remainder is 0.041.
