Let's divide 666259 by 89
Let's see how many times 89 fits into 666259.

Advancing to step 1:
6 divided by 89 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 89

Step 2:
89 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 89

Moving on to step 3:
The number 89 fits into 666 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 623 away from 666, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 89

Let's proceed to step 4:
89 goes into 432 4 times with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 356 from 432 to get 76.
Append the next digit (5) from the dividend to 76 and continue with: 765 / 89

Going ahead to step 5:
89 goes into 765 8 times with a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 748.0
Deduct 712 from 765 and we're left with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 89

Moving on to step 6:
When dividing 539 by 89, we get 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 7486.0
If we take 534 away from 539, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 89 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 7486.0
If we take 0 away from 50, we end up 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.

Let's proceed to step 8:
The number 89 fits into 500 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 7486.05
If we take 445 away from 500, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
550 divided by 89 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 7486.056
If we subtract 534 from 550, we 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.

Advancing to step 10:
The number 89 fits into 160 1 times, leaving a remainder of 71.
The next digit of our result is 1. 
Result so far: 7486.0561
If we take 89 away from 160, we end up with 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 11:
If we divide 710 by 89, we get 7 and a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 7486.05617
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.

Step 12:
The number 89 fits into 870 9 times, leaving a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 7486.056179
Subtract 801 from 870 to get 69.
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 13:
89 goes into 690 7 times with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 7486.0561797
If we subtract 623 from 690, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 14:
670 divided by 89 is 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 7486.05617977
If we take 623 away from 670, we end up with 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 7486.05617977, with a leftover of 4.7e-08.
