We're dividing 661500 by 4 
We want to divide 661500 by 4.

On to step 1:
6 divided by 4 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 4 from 6 to get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Let's proceed to step 2:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 24 from 26, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Moving on to step 3:
If we divide 21 by 4, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 165.0
The remainder is 1 after subtracting 20 from 21.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 4

Step 4:
15 divided by 4 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1653.0
Subtract 12 from 15 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 4

Going ahead to step 5:
30 divided by 4 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 16537.0
Subtract 28 from 30 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Let's proceed to step 6:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 165375.0
If we take 20 away from 20, 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.

Let's proceed to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 165375.0
The remainder is 0 after subtracting 0 from 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 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 165375.0
Subtracting 0 from 0 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.

The quotient of the division is 165375.0, and the remainder is 0.0.
