Let's divide 146640 by 4
We want to divide 146640 by 4.

Step 1:
4 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Advancing to step 2:
14 divided by 4 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 2 after subtracting 12 from 14.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Step 3:
4 goes into 26 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 24 from 26 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Going ahead to step 4:
4 goes into 26 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 366.0
If we subtract 24 from 26, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 4

On to step 5:
If we divide 24 by 4, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 3666.0
Deduct 24 from 24 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Let's proceed to step 6:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36660.0
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.

Advancing to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 36660.0
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.

Step 8:
4 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36660.0
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.

Our division results in 36660.0 with a remaining 0.0.
