666027 divided by 91 
We want to divide 666027 by 91.

Step 1:
6 divided by 91 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 91

Step 2:
When dividing 66 by 91, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 91

On to step 3:
The number 91 fits into 666 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 637 from 666, we get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 91

Moving on to step 4:
The number 91 fits into 290 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Deduct 273 from 290 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 91

On to step 5:
When dividing 172 by 91, we get 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 731.0
The remainder is 81 after subtracting 91 from 172.
Include the next digit (7) from the dividend after 81, then repeat: 817 / 91

Going ahead to step 6:
91 can be fit into 817 8 times, resulting in a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 7318.0
If we subtract 728 from 817, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 7:
The number 91 fits into 890 9 times, leaving a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 7318.9
Subtracting 819 from 890 leaves us 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.

Advancing to step 8:
If we divide 710 by 91, we get 7 and a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 7318.97
If we take 637 away from 710, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
If we divide 730 by 91, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 7318.978
If we take 728 away from 730, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
91 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 7318.978
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
91 goes into 200 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 7318.97802
Subtracting 182 from 200 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
If we divide 180 by 91, we get 1 and a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 7318.978021
Subtract 91 from 180 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 13:
91 can be fit into 890 9 times, resulting in a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7318.9780219
Subtract 819 from 890 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.

Advancing to step 14:
91 goes into 710 7 times with a remainder of 73.
The next digit of our result is 7. 
Result so far: 7318.97802197
If we subtract 637 from 710, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

In conclusion, the division gives 7318.97802197 with a balance of 7.3e-08.
