150686 ÷ 631 
Our goal is to divide 150686 by 631.

Let's proceed to step 1:
631 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 631

Going ahead to step 2:
When dividing 15 by 631, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 631

Advancing to step 3:
631 goes into 150 0 times with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 150, we get 150.
Include the next digit (6) from the dividend after 150, then repeat: 1506 / 631

Going ahead to step 4:
1506 divided by 631 is 2 with a remainder of 244.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1262 from 1506 and we're left with 244.
Fetch the next digit (8) from the dividend, attach it to 244 and continue: 2448 / 631

Going ahead to step 5:
When dividing 2448 by 631, we get 3 with a remainder of 555.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 1893 from 2448 and we're left with 555.
Take the next digit (6) from the dividend and append it to 555, then repeat: 5556 / 631

Going ahead to step 6:
The number 631 fits into 5556 8 times, leaving a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Subtracting 5048 from 5556 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 7:
631 goes into 5080 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 238.8
If we take 5048 away from 5080, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
If we divide 320 by 631, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 238.8
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 9:
3200 divided by 631 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 238.805
If we take 3155 away from 3200, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
If we divide 450 by 631, we get 0 and a remainder of 450.
The next digit of our result is 0. 
Result so far: 238.805
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 11:
When dividing 4500 by 631, we get 7 with a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 238.80507
Deduct 4417 from 4500 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 12:
631 can be fit into 830 1 times, resulting in a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 238.805071
Subtracting 631 from 830 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 13:
631 goes into 1990 3 times with a remainder of 97.
The next digit of our result is 3. 
Result so far: 238.8050713
The remainder is 97 after subtracting 1893 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 14:
If we divide 970 by 631, we get 1 and a remainder of 339.
Record the quotient 1 as the next digit in the result. 
Result so far: 238.80507131
Subtracting 631 from 970 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

In conclusion, the division gives 238.80507131 with a balance of 3.39e-07.
