666312 ÷ 91 
We want to divide 666312 by 91.

Moving on to step 1:
If we divide 6 by 91, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 91

Going ahead to step 2:
The number 91 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 91

Step 3:
666 divided by 91 is 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 637 from 666 and we're left with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 91

On to step 4:
91 can be fit into 293 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Deduct 273 from 293 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 91

Going ahead to step 5:
91 goes into 201 2 times with a remainder of 19.
The next digit of our result is 2. 
Result so far: 732.0
The remainder is 19 after subtracting 182 from 201.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 91

Advancing to step 6:
192 divided by 91 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 7322.0
Subtract 182 from 192 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
91 can be fit into 100 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 7322.1
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
If we divide 90 by 91, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 7322.1
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
900 divided by 91 is 9 with a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 7322.109
Subtract 819 from 900 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
91 can be fit into 810 8 times, resulting in a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 7322.1098
If we take 728 away from 810, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
91 can be fit into 820 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7322.10989
Subtracting 819 from 820 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
If we divide 10 by 91, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7322.10989
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
100 divided by 91 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 7322.1098901
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
90 divided by 91 is 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 7322.1098901
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

The quotient of the division is 7322.1098901, and the remainder is 9e-08.
