We're dividing 1605625 by 800 
Our goal is to divide 1605625 by 800.

Advancing to step 1:
The number 800 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 800

Advancing to step 2:
The number 800 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 800

Going ahead to step 3:
160 divided by 800 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 160 leaves us with 160.
Fetch the next digit (5) from the dividend, attach it to 160 and continue: 1605 / 800

Going ahead to step 4:
The number 800 fits into 1605 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 5 after subtracting 1600 from 1605.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 800

Going ahead to step 5:
800 can be fit into 56 0 times, resulting in a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 56 leaves us with 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 800

Advancing to step 6:
When dividing 562 by 800, we get 0 with a remainder of 562.
Put 0 as the next digit of the answer. 
Result so far: 200.0
If we subtract 0 from 562, we get 562.
Fetch the next digit (5) from the dividend, attach it to 562 and continue: 5625 / 800

On to step 7:
If we divide 5625 by 800, we get 7 and a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 2007.0
Deduct 5600 from 5625 and we're left 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.

Step 8:
250 divided by 800 is 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 2007.0
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 9:
800 can be fit into 2500 3 times, resulting in a remainder of 100.
The next digit of our result is 3. 
Result so far: 2007.03
Deduct 2400 from 2500 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
800 goes into 1000 1 times with a remainder of 200.
The number 1 becomes the next digit in our result. 
Result so far: 2007.031
The remainder is 200 after subtracting 800 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
The number 800 fits into 2000 2 times, leaving a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 2007.0312
The remainder is 400 after subtracting 1600 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 12:
4000 divided by 800 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2007.03125
If we take 4000 away from 4000, 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 13:
0 divided by 800 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2007.03125
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.

Moving on to step 14:
800 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2007.03125
Subtract 0 from 0 to get 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 result is 2007.03125 with a remainder of 0.0.
