We look at the division of 21459459 by 650 
Let's see how many times 650 fits into 21459459.

Advancing to step 1:
650 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
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 650

Advancing to step 2:
If we divide 21 by 650, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 650

On to step 3:
If we divide 214 by 650, we get 0 and a remainder of 214.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 214, we end up with 214.
Append the next digit (5) from the dividend to 214 and continue with: 2145 / 650

On to step 4:
650 goes into 2145 3 times with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1950 from 2145 and we're left with 195.
Take the next digit (9) from the dividend and append it to 195, then repeat: 1959 / 650

Step 5:
When dividing 1959 by 650, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 1950 from 1959 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 650

Moving on to step 6:
The number 650 fits into 94 0 times, leaving a remainder of 94.
Put 0 as the next digit of the answer. 
Result so far: 330.0
The remainder is 94 after subtracting 0 from 94.
Take the next digit (5) from the dividend and append it to 94, then repeat: 945 / 650

Moving on to step 7:
When dividing 945 by 650, we get 1 with a remainder of 295.
Write down 1 as next digit of the result. 
Result so far: 3301.0
Subtract 650 from 945 to get 295.
Grab the next digit (9) from the dividend, add it to 295, then carry on: 2959 / 650

Step 8:
650 can be fit into 2959 4 times, resulting in a remainder of 359.
Write down 4 as next digit of the result. 
Result so far: 33014.0
Deduct 2600 from 2959 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 9:
650 goes into 3590 5 times with a remainder of 340.
Write down 5 as next digit of the result. 
Result so far: 33014.5
If we take 3250 away from 3590, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 10:
650 can be fit into 3400 5 times, resulting in a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 33014.55
Deduct 3250 from 3400 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Our division results in 33014.55 with a remaining 0.15.
