We look at the division of 162155 by 72 
We want to figure out the number of times 162155 can be divided by 72.

Going ahead to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 72

Step 2:
72 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 72

Let's proceed to step 3:
When dividing 162 by 72, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 18 after subtracting 144 from 162.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 72

Let's proceed to step 4:
72 goes into 181 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 144 from 181 and we're left with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 72

Advancing to step 5:
72 goes into 375 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 225.0
If we subtract 360 from 375, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 72

Advancing to step 6:
When dividing 155 by 72, we get 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2252.0
Deduct 144 from 155 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
72 goes into 110 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 2252.1
If we take 72 away from 110, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
If we divide 380 by 72, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2252.15
If we subtract 360 from 380, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 72 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 2252.152
If we subtract 144 from 200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
If we divide 560 by 72, we get 7 and a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 2252.1527
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
The number 72 fits into 560 7 times, leaving a remainder of 56.
The next digit of our result is 7. 
Result so far: 2252.15277
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 2252.15277 with a remainder of 5.6e-05.
