We're dividing 393557 by 89 
We want to divide 393557 by 89.

On to step 1:
3 divided by 89 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 89

Going ahead to step 2:
If we divide 39 by 89, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 89

Moving on to step 3:
393 divided by 89 is 4 with a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 356 from 393 leaves us with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 89

Moving on to step 4:
When dividing 375 by 89, we get 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 44.0
If we take 356 away from 375, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 89

Going ahead to step 5:
89 goes into 195 2 times with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
Subtracting 178 from 195 leaves us with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 89

Going ahead to step 6:
The number 89 fits into 177 1 times, leaving a remainder of 88.
Use 1 as the next digit of our solution. 
Result so far: 4421.0
If we subtract 89 from 177, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 7:
When dividing 880 by 89, we get 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 4421.9
If we take 801 away from 880, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 8:
89 can be fit into 790 8 times, resulting in a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 4421.98
If we subtract 712 from 790, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
89 goes into 780 8 times with a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 4421.988
Subtracting 712 from 780 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final outcome is 4421.988, with a leftover of 0.0068.
