Let's divide 150161 by 4
Let's see how many times 4 fits into 150161.

Step 1:
If we divide 1 by 4, we get 0 and 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 (5) from the dividend to 1 and continue with: 15 / 4

Moving on to step 2:
The number 4 fits into 15 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 12 from 15 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 4

Advancing to step 3:
30 divided by 4 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 28 from 30, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 4

On to step 4:
21 divided by 4 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 375.0
The remainder is 1 after subtracting 20 from 21.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

On to step 5:
When dividing 16 by 4, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 3754.0
If we take 16 away from 16, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 4

Going ahead to step 6:
When dividing 1 by 4, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 37540.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 4 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 37540.2
Subtract 8 from 10 to 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.

Let's proceed to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 37540.25
The remainder is 0 after subtracting 20 from 20.
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 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37540.25
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.

Let's proceed to step 10:
4 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 37540.25
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.

In conclusion, the division gives 37540.25 with a balance of 0.0.
