Let's divide 10539191 by 773
We want to figure out the number of times 10539191 can be divided by 773.

Let's proceed to step 1:
If we divide 1 by 773, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 773

On to step 2:
773 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 773

Advancing to step 3:
773 goes into 105 0 times with a remainder of 105.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 105 and we're left with 105.
Include the next digit (3) from the dividend after 105, then repeat: 1053 / 773

Going ahead to step 4:
773 goes into 1053 1 times with a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 773 from 1053, we get 280.
Include the next digit (9) from the dividend after 280, then repeat: 2809 / 773

Moving on to step 5:
The number 773 fits into 2809 3 times, leaving a remainder of 490.
The next digit of our result is 3. 
Result so far: 13.0
If we take 2319 away from 2809, we end up with 490.
Append the next digit (1) from the dividend to 490 and continue with: 4901 / 773

Moving on to step 6:
When dividing 4901 by 773, we get 6 with a remainder of 263.
The next digit of our result is 6. 
Result so far: 136.0
If we take 4638 away from 4901, we end up with 263.
Fetch the next digit (9) from the dividend, attach it to 263 and continue: 2639 / 773

Moving on to step 7:
773 goes into 2639 3 times with a remainder of 320.
Use 3 as the next digit of our solution. 
Result so far: 1363.0
If we subtract 2319 from 2639, we get 320.
Append the next digit (1) from the dividend to 320 and continue with: 3201 / 773

Moving on to step 8:
773 goes into 3201 4 times with a remainder of 109.
Use 4 as the next digit of our solution. 
Result so far: 13634.0
Subtract 3092 from 3201 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 9:
The number 773 fits into 1090 1 times, leaving a remainder of 317.
The next digit of our result is 1. 
Result so far: 13634.1
If we take 773 away from 1090, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

On to step 10:
When dividing 3170 by 773, we get 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 13634.14
Subtract 3092 from 3170 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
When dividing 780 by 773, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 13634.141
Subtract 773 from 780 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
When dividing 70 by 773, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 13634.141
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
700 divided by 773 is 0 with a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 13634.141
Deduct 0 from 700 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 13634.141, with a leftover of 0.0007.
