We're dividing 155631 by 72 
Our goal is to divide 155631 by 72.

Let's proceed to step 1:
72 goes into 1 0 times 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 (5) from the dividend, add it to 1, then carry on: 15 / 72

Moving on to step 2:
72 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 72

Step 3:
If we divide 155 by 72, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we take 144 away from 155, we end up with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 72

Going ahead to step 4:
72 goes into 116 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 72 from 116, we get 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 72

Step 5:
If we divide 443 by 72, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
The remainder is 11 after subtracting 432 from 443.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 72

Going ahead to step 6:
The number 72 fits into 111 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 2161.0
Subtracting 72 from 111 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
72 goes into 390 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 2161.5
Deduct 360 from 390 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 72 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2161.54
If we take 288 away from 300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 72 fits into 120 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 2161.541
The remainder is 48 after subtracting 72 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
72 goes into 480 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 2161.5416
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 72, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 2161.54166
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 2161.54166 with a remaining 4.8e-05.
