We divide 160170 by 25
We're looking to find how many times 25 goes into 160170.

Going ahead to step 1:
1 divided by 25 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 25

On to step 2:
If we divide 16 by 25, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 25

Moving on to step 3:
If we divide 160 by 25, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 150 from 160 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 25

Going ahead to step 4:
When dividing 101 by 25, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 1 after subtracting 100 from 101.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 25

Moving on to step 5:
25 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 640.0
Subtract 0 from 17 to get 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 25

On to step 6:
When dividing 170 by 25, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 6406.0
Subtracting 150 from 170 leaves us 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.

Step 7:
If we divide 200 by 25, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 6406.8
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6406.8
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 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6406.8
If we take 0 away from 0, 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.

The final outcome is 6406.8, with a leftover of 0.0.
