155139 divided by 72 
Let's see how many times 72 fits into 155139.

On to step 1:
72 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 72

Moving on to step 2:
72 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 72

Let's proceed to step 3:
72 goes into 155 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 144 from 155, we get 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 72

Going ahead to step 4:
When dividing 111 by 72, we get 1 with a remainder of 39.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 72 from 111 leaves us with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 72

Let's proceed to step 5:
72 goes into 393 5 times with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Subtract 360 from 393 to get 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 72

Let's proceed to step 6:
72 can be fit into 339 4 times, resulting in a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 2154.0
If we subtract 288 from 339, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
72 can be fit into 510 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 2154.7
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 72 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 2154.7
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2154.708
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 2154.7083
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 2154.70833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 2154.70833, and the remainder is 2.4e-05.
