We're dividing 50393313 by 91 
We want to figure out the number of times 50393313 can be divided by 91.

Let's proceed to step 1:
If we divide 5 by 91, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 91

Step 2:
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: 0.0
If we subtract 0 from 50, we get 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 91

On to step 3:
The number 91 fits into 503 5 times, leaving a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 455 from 503 leaves us with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 91

On to step 4:
The number 91 fits into 489 5 times, leaving a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 34 after subtracting 455 from 489.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 91

Step 5:
The number 91 fits into 343 3 times, leaving a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 553.0
If we take 273 away from 343, we end up with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 91

Step 6:
91 can be fit into 703 7 times, resulting in a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 5537.0
Deduct 637 from 703 and we're left with 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 91

Going ahead to step 7:
If we divide 661 by 91, we get 7 and a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 55377.0
If we take 637 away from 661, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 91

On to step 8:
The number 91 fits into 243 2 times, leaving a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 553772.0
Subtracting 182 from 243 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
The number 91 fits into 610 6 times, leaving a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 553772.6
Deduct 546 from 610 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
640 divided by 91 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 553772.67
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
When dividing 30 by 91, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 553772.67
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 91, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 553772.6703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
91 goes into 270 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 553772.67032
Subtracting 182 from 270 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
When dividing 880 by 91, we get 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 553772.670329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 15:
When dividing 610 by 91, we get 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 553772.6703296
Subtracting 546 from 610 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
91 goes into 640 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 553772.67032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 553772.67032967 and a remainder of 3e-09.
