We look at the division of 578605 by 89 
We want to divide 578605 by 89.

Step 1:
The number 89 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 89

Moving on to step 2:
If we divide 57 by 89, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 89

Moving on to step 3:
The number 89 fits into 578 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 44 after subtracting 534 from 578.
Grab the next digit (6) from the dividend, add it to 44, then carry on: 446 / 89

On to step 4:
89 can be fit into 446 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 445 away from 446, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 89

Going ahead to step 5:
89 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 89

Step 6:
105 divided by 89 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 6501.0
Subtract 89 from 105 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
89 goes into 160 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 6501.1
Subtract 89 from 160 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 8:
When dividing 710 by 89, we get 7 with a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 6501.17
Deduct 623 from 710 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 9:
If we divide 870 by 89, we get 9 and a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 6501.179
The remainder is 69 after subtracting 801 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
89 can be fit into 690 7 times, resulting in a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 6501.1797
If we take 623 away from 690, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
When dividing 670 by 89, we get 7 with a remainder of 47.
The next digit of our result is 7. 
Result so far: 6501.17977
If we subtract 623 from 670, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final outcome is 6501.17977, with a leftover of 4.7e-05.
