We look at the division of 623930 by 91 
Let's see how many times 91 fits into 623930.

Moving on to step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 91

Let's proceed to step 2:
When dividing 62 by 91, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 91

Step 3:
When dividing 623 by 91, we get 6 with a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 546 away from 623, we end up with 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 91

Step 4:
The number 91 fits into 779 8 times, leaving a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 728 from 779 leaves us with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 91

Step 5:
91 can be fit into 513 5 times, resulting in a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 685.0
If we take 455 away from 513, we end up with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 91

Step 6:
91 can be fit into 580 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 6856.0
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
The number 91 fits into 340 3 times, leaving a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 6856.3
If we subtract 273 from 340, 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 8:
When dividing 670 by 91, we get 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 6856.37
Subtracting 637 from 670 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
If we divide 330 by 91, we get 3 and a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 6856.373
If we take 273 away from 330, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 10:
When dividing 570 by 91, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 6856.3736
If we take 546 away from 570, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
The number 91 fits into 240 2 times, leaving a remainder of 58.
The next digit of our result is 2. 
Result so far: 6856.37362
Subtracting 182 from 240 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
The number 91 fits into 580 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 6856.373626
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
The number 91 fits into 340 3 times, leaving a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 6856.3736263
Subtracting 273 from 340 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 14:
When dividing 670 by 91, we get 7 with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 6856.37362637
If we take 637 away from 670, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final result is 6856.37362637 with a remainder of 3.3e-08.
