We're dividing 143963 by 35 
Our goal is to divide 143963 by 35.

Let's proceed to step 1:
The number 35 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 35

Let's proceed to step 2:
When dividing 14 by 35, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 35

Let's proceed to step 3:
When dividing 143 by 35, we get 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 3 after subtracting 140 from 143.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 35

Step 4:
35 goes into 39 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 35 from 39, we get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 35

Going ahead to step 5:
35 can be fit into 46 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 411.0
If we take 35 away from 46, we end up with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 35

On to step 6:
35 goes into 113 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 4113.0
If we subtract 105 from 113, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 35, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 4113.2
The remainder is 10 after subtracting 70 from 80.
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:
100 divided by 35 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 4113.22
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 4113.22 with a remaining 0.03.
