3162116 ÷ 800 
Let's see how many times 800 fits into 3162116.

Going ahead to step 1:
When dividing 3 by 800, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 800

Going ahead to step 2:
800 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 800

On to step 3:
316 divided by 800 is 0 with a remainder of 316.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 316, we get 316.
Bring next digit (2) of the dividend behind the 316 and repeat the process: 3162 / 800

Going ahead to step 4:
If we divide 3162 by 800, we get 3 and a remainder of 762.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2400 from 3162 and we're left with 762.
Bring next digit (1) of the dividend behind the 762 and repeat the process: 7621 / 800

Let's proceed to step 5:
When dividing 7621 by 800, we get 9 with a remainder of 421.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 7200 from 7621 leaves us with 421.
Take the next digit (1) from the dividend and append it to 421, then repeat: 4211 / 800

On to step 6:
When dividing 4211 by 800, we get 5 with a remainder of 211.
The next digit of our result is 5. 
Result so far: 395.0
If we take 4000 away from 4211, we end up with 211.
Take the next digit (6) from the dividend and append it to 211, then repeat: 2116 / 800

Moving on to step 7:
2116 divided by 800 is 2 with a remainder of 516.
Put 2 as the next digit of the answer. 
Result so far: 3952.0
The remainder is 516 after subtracting 1600 from 2116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 8:
The number 800 fits into 5160 6 times, leaving a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 3952.6
If we take 4800 away from 5160, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 9:
800 can be fit into 3600 4 times, resulting in a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 3952.64
Subtract 3200 from 3600 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
If we divide 4000 by 800, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3952.645
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.

Step 11:
If we divide 0 by 800, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3952.645
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.

Going ahead to step 12:
800 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3952.645
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.

After the division, we end up with 3952.645 and a remainder of 0.0.
