We divide 810345 by 75
We want to divide 810345 by 75.

On to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 75

On to step 2:
75 can be fit into 81 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 81 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 75

Let's proceed to step 3:
If we divide 60 by 75, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 60 to get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 75

On to step 4:
If we divide 603 by 75, we get 8 and a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we subtract 600 from 603, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 75

Moving on to step 5:
75 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 1080.0
If we take 0 away from 34, we end up with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 75

Going ahead to step 6:
When dividing 345 by 75, we get 4 with a remainder of 45.
Record the quotient 4 as the next digit in the result. 
Result so far: 10804.0
If we subtract 300 from 345, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
If we divide 450 by 75, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 10804.6
Subtract 450 from 450 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.

On to step 8:
When dividing 0 by 75, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10804.6
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.

Moving on to step 9:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10804.6
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.

The final outcome is 10804.6, with a leftover of 0.0.
