25744817 ÷ 172 
We want to figure out the number of times 25744817 can be divided by 172.

Advancing to step 1:
When dividing 2 by 172, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 172

On to step 2:
172 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 172

On to step 3:
If we divide 257 by 172, we get 1 and a remainder of 85.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 172 from 257 and we're left with 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 172

Step 4:
When dividing 854 by 172, we get 4 with a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 688 away from 854, we end up with 166.
Include the next digit (4) from the dividend after 166, then repeat: 1664 / 172

Going ahead to step 5:
172 can be fit into 1664 9 times, resulting in a remainder of 116.
The next digit of our result is 9. 
Result so far: 149.0
If we subtract 1548 from 1664, we get 116.
Include the next digit (8) from the dividend after 116, then repeat: 1168 / 172

Going ahead to step 6:
When dividing 1168 by 172, we get 6 with a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 1496.0
The remainder is 136 after subtracting 1032 from 1168.
Bring next digit (1) of the dividend behind the 136 and repeat the process: 1361 / 172

Moving on to step 7:
172 can be fit into 1361 7 times, resulting in a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 14967.0
If we subtract 1204 from 1361, we get 157.
Append the next digit (7) from the dividend to 157 and continue with: 1577 / 172

On to step 8:
172 can be fit into 1577 9 times, resulting in a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 149679.0
Deduct 1548 from 1577 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
The number 172 fits into 290 1 times, leaving a remainder of 118.
The number 1 becomes the next digit in our result. 
Result so far: 149679.1
Deduct 172 from 290 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
The number 172 fits into 1180 6 times, leaving a remainder of 148.
Record the quotient 6 as the next digit in the result. 
Result so far: 149679.16
Deduct 1032 from 1180 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 11:
1480 divided by 172 is 8 with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 149679.168
Subtracting 1376 from 1480 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 12:
If we divide 1040 by 172, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 149679.1686
The remainder is 8 after subtracting 1032 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
When dividing 80 by 172, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 149679.1686
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
172 can be fit into 800 4 times, resulting in a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 149679.168604
If we take 688 away from 800, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
When dividing 1120 by 172, we get 6 with a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 149679.1686046
The remainder is 88 after subtracting 1032 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
If we divide 880 by 172, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 149679.16860465
Deduct 860 from 880 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 149679.16860465 with a balance of 2e-08.
