25420645 divided by 173 
We want to figure out the number of times 25420645 can be divided by 173.

Step 1:
173 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
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 173

Going ahead to step 2:
The number 173 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 173

On to step 3:
173 can be fit into 254 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 1.0
If we take 173 away from 254, we end up with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 173

Going ahead to step 4:
812 divided by 173 is 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 692 from 812 leaves us with 120.
Grab the next digit (0) from the dividend, add it to 120, then carry on: 1200 / 173

Advancing to step 5:
The number 173 fits into 1200 6 times, leaving a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 146.0
The remainder is 162 after subtracting 1038 from 1200.
Append the next digit (6) from the dividend to 162 and continue with: 1626 / 173

Moving on to step 6:
The number 173 fits into 1626 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 1469.0
If we subtract 1557 from 1626, we get 69.
Take the next digit (4) from the dividend and append it to 69, then repeat: 694 / 173

Step 7:
173 goes into 694 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14694.0
The remainder is 2 after subtracting 692 from 694.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 173

Going ahead to step 8:
If we divide 25 by 173, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 146940.0
If we take 0 away from 25, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
If we divide 250 by 173, we get 1 and a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 146940.1
Subtracting 173 from 250 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
770 divided by 173 is 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 146940.14
Deduct 692 from 770 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
When dividing 780 by 173, we get 4 with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 146940.144
If we subtract 692 from 780, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 146940.144 and a remainder of 0.0088.
