Let's divide 73578 by 86
Our goal is to divide 73578 by 86.

On to step 1:
86 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 86

On to step 2:
If we divide 73 by 86, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 86

Let's proceed to step 3:
The number 86 fits into 735 8 times, leaving a remainder of 47.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 688 from 735 to get 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 86

Moving on to step 4:
477 divided by 86 is 5 with a remainder of 47.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we take 430 away from 477, we end up with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 86

Advancing to step 5:
86 goes into 478 5 times with a remainder of 48.
The next digit of our result is 5. 
Result so far: 855.0
Deduct 430 from 478 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 6:
When dividing 480 by 86, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 855.5
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 855.55
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 855.55 with a balance of 0.07.
