140959 ÷ 4 
Our goal is to divide 140959 by 4.

Step 1:
1 divided by 4 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 4

Going ahead to step 2:
If we divide 14 by 4, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 12 from 14 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 4

On to step 3:
If we divide 20 by 4, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 0 after subtracting 20 from 20.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

On to step 4:
If we divide 9 by 4, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 352.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 4

Going ahead to step 5:
When dividing 15 by 4, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3523.0
Deduct 12 from 15 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 4

Moving on to step 6:
39 divided by 4 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 35239.0
If we take 36 away from 39, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
4 goes into 30 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 35239.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 35239.75
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.

On to step 9:
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: 35239.75
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.

Advancing to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35239.75
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.

The final result is 35239.75 with a remainder of 0.0.
