75604293 divided by 815 
We want to divide 75604293 by 815.

On to step 1:
When dividing 7 by 815, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 815

Moving on to step 2:
75 divided by 815 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 815

Moving on to step 3:
815 can be fit into 756 0 times, resulting in a remainder of 756.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 756 to get 756.
Bring next digit (0) of the dividend behind the 756 and repeat the process: 7560 / 815

Going ahead to step 4:
7560 divided by 815 is 9 with a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7335 from 7560 and we're left with 225.
Fetch the next digit (4) from the dividend, attach it to 225 and continue: 2254 / 815

Going ahead to step 5:
The number 815 fits into 2254 2 times, leaving a remainder of 624.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 1630 from 2254 leaves us with 624.
Fetch the next digit (2) from the dividend, attach it to 624 and continue: 6242 / 815

Advancing to step 6:
When dividing 6242 by 815, we get 7 with a remainder of 537.
Write down 7 as next digit of the result. 
Result so far: 927.0
If we take 5705 away from 6242, we end up with 537.
Bring next digit (9) of the dividend behind the 537 and repeat the process: 5379 / 815

Step 7:
815 goes into 5379 6 times with a remainder of 489.
The number 6 becomes the next digit in our result. 
Result so far: 9276.0
Subtract 4890 from 5379 to get 489.
Include the next digit (3) from the dividend after 489, then repeat: 4893 / 815

Step 8:
If we divide 4893 by 815, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 92766.0
If we take 4890 away from 4893, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
815 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 92766.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 815 is 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 92766.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 92766.0, with a leftover of 0.3.
