150850 ÷ 4 
We want to figure out the number of times 150850 can be divided by 4.

Step 1:
When dividing 1 by 4, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

On to step 2:
If we divide 15 by 4, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 12 away from 15, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 4

Moving on to step 3:
4 goes into 30 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 28 from 30 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Step 4:
4 goes into 28 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 377.0
Subtract 28 from 28 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 4

Moving on to step 5:
When dividing 5 by 4, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 3771.0
If we subtract 4 from 5, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 4

Going ahead to step 6:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 37712.0
Deduct 8 from 10 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 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 37712.5
If we subtract 20 from 20, 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.

Moving on to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37712.5
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.

On to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 37712.5
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.

After the division, we end up with 37712.5 and a remainder of 0.0.
