668627 divided by 91 
Let's see how many times 91 fits into 668627.

Moving on to step 1:
If we divide 6 by 91, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 91

Advancing 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
If we take 0 away from 66, we end up with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 91

On to step 3:
The number 91 fits into 668 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 637 from 668, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 91

Moving on to step 4:
When dividing 316 by 91, we get 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 273 from 316 leaves us with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 91

Advancing to step 5:
If we divide 432 by 91, we get 4 and a remainder of 68.
The next digit of our result is 4. 
Result so far: 734.0
Subtract 364 from 432 to get 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 91

Let's proceed to step 6:
The number 91 fits into 687 7 times, leaving a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 7347.0
Subtracting 637 from 687 leaves us 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.

Advancing to step 7:
91 can be fit into 500 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 7347.5
The remainder is 45 after subtracting 455 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
When dividing 450 by 91, we get 4 with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 7347.54
Deduct 364 from 450 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
If we divide 860 by 91, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 7347.549
If we subtract 819 from 860, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
91 can be fit into 410 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 7347.5494
Deduct 364 from 410 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
91 goes into 460 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7347.54945
If we subtract 455 from 460, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
If we divide 50 by 91, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 7347.54945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
500 divided by 91 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 7347.5494505
If we subtract 455 from 500, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
If we divide 450 by 91, we get 4 and a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 7347.54945054
If we subtract 364 from 450, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 7347.54945054, with a leftover of 8.6e-08.
