We're dividing 133951 by 4 
We're looking to find how many times 4 goes into 133951.

On to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 4

Moving on to step 2:
The number 4 fits into 13 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 12 away from 13, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 4

Step 3:
13 divided by 4 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 12 from 13 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Let's proceed to step 4:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 334.0
Deduct 16 from 19 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 4

Step 5:
35 divided by 4 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 3348.0
Subtracting 32 from 35 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 4

Moving on to step 6:
4 can be fit into 31 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 33487.0
If we take 28 away from 31, 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:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 33487.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 33487.75
Subtract 20 from 20 to get 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 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 33487.75
Subtract 0 from 0 to get 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 10:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33487.75
If we subtract 0 from 0, we get 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 33487.75, and the remainder is 0.0.
