We're dividing 91073340 by 393 
Our goal is to divide 91073340 by 393.

Advancing to step 1:
393 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 393

Moving on to step 2:
91 divided by 393 is 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 393

Advancing to step 3:
The number 393 fits into 910 2 times, leaving a remainder of 124.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 786 away from 910, we end up with 124.
Append the next digit (7) from the dividend to 124 and continue with: 1247 / 393

Step 4:
When dividing 1247 by 393, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 1179 from 1247 and we're left with 68.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 393

Let's proceed to step 5:
393 can be fit into 683 1 times, resulting in a remainder of 290.
Write down 1 as next digit of the result. 
Result so far: 231.0
If we subtract 393 from 683, we get 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 393

Step 6:
If we divide 2903 by 393, we get 7 and a remainder of 152.
Record the quotient 7 as the next digit in the result. 
Result so far: 2317.0
The remainder is 152 after subtracting 2751 from 2903.
Fetch the next digit (4) from the dividend, attach it to 152 and continue: 1524 / 393

On to step 7:
393 goes into 1524 3 times with a remainder of 345.
Use 3 as the next digit of our solution. 
Result so far: 23173.0
Subtracting 1179 from 1524 leaves us with 345.
Bring next digit (0) of the dividend behind the 345 and repeat the process: 3450 / 393

Advancing to step 8:
393 goes into 3450 8 times with a remainder of 306.
The number 8 becomes the next digit in our result. 
Result so far: 231738.0
If we subtract 3144 from 3450, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 9:
The number 393 fits into 3060 7 times, leaving a remainder of 309.
Write down 7 as next digit of the result. 
Result so far: 231738.7
If we subtract 2751 from 3060, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 10:
3090 divided by 393 is 7 with a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 231738.77
The remainder is 339 after subtracting 2751 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

The final result is 231738.77 with a remainder of 0.339.
