164139 divided by 25 
Let's see how many times 25 fits into 164139.

Moving on to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 25

Going ahead to step 2:
16 divided by 25 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 25

Going ahead to step 3:
25 can be fit into 164 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 150 from 164 and we're left with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 25

Going ahead to step 4:
25 goes into 141 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtract 125 from 141 to get 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 25

Let's proceed to step 5:
If we divide 163 by 25, we get 6 and a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 656.0
Subtract 150 from 163 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 25

On to step 6:
If we divide 139 by 25, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 6565.0
Subtracting 125 from 139 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 25, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6565.5
Subtract 125 from 140 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6565.56
If we take 150 away from 150, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6565.56
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6565.56
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 6565.56 and a remainder of 0.0.
