We look at the division of 25115173 by 179 
We want to figure out the number of times 25115173 can be divided by 179.

Step 1:
179 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 179

On to step 2:
If we divide 25 by 179, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 179

Moving on to step 3:
251 divided by 179 is 1 with a remainder of 72.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 179 from 251 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 179

On to step 4:
721 divided by 179 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 5 after subtracting 716 from 721.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 179

Advancing to step 5:
If we divide 55 by 179, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Deduct 0 from 55 and we're left with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 179

Step 6:
When dividing 551 by 179, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 1403.0
The remainder is 14 after subtracting 537 from 551.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 179

Let's proceed to step 7:
The number 179 fits into 147 0 times, leaving a remainder of 147.
The number 0 becomes the next digit in our result. 
Result so far: 14030.0
Subtracting 0 from 147 leaves us with 147.
Include the next digit (3) from the dividend after 147, then repeat: 1473 / 179

Advancing to step 8:
The number 179 fits into 1473 8 times, leaving a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 140308.0
If we subtract 1432 from 1473, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
179 goes into 410 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 140308.2
Subtract 358 from 410 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 179 is 2 with a remainder of 162.
The next digit of our result is 2. 
Result so far: 140308.22
Subtract 358 from 520 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 140308.22, with a leftover of 0.162.
