667648 ÷ 91 
Let's see how many times 91 fits into 667648.

Moving on to step 1:
If we divide 6 by 91, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 91

Let's proceed to step 2:
The number 91 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 91

Let's proceed to step 3:
91 can be fit into 667 7 times, resulting in a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 637 from 667 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 91

Advancing to step 4:
The number 91 fits into 306 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 73.0
If we subtract 273 from 306, we get 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 91

Let's proceed to step 5:
The number 91 fits into 334 3 times, leaving a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 733.0
Subtracting 273 from 334 leaves us with 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 91

Step 6:
618 divided by 91 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 7336.0
If we take 546 away from 618, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
If we divide 720 by 91, we get 7 and a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 7336.7
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 8:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 7336.79
Subtracting 819 from 830 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
110 divided by 91 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 7336.791
If we subtract 91 from 110, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
190 divided by 91 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7336.7912
Deduct 182 from 190 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 91 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 7336.7912
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
91 goes into 800 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 7336.791208
If we subtract 728 from 800, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
91 goes into 720 7 times with a remainder of 83.
The next digit of our result is 7. 
Result so far: 7336.7912087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 14:
91 goes into 830 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 7336.79120879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 7336.79120879, with a leftover of 1.1e-08.
