We're dividing 45389063 by 773 
Let's see how many times 773 fits into 45389063.

On to step 1:
773 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 773

Step 2:
The number 773 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 773

Going ahead to step 3:
773 goes into 453 0 times with a remainder of 453.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 453 after subtracting 0 from 453.
Take the next digit (8) from the dividend and append it to 453, then repeat: 4538 / 773

Going ahead to step 4:
4538 divided by 773 is 5 with a remainder of 673.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3865 from 4538 to get 673.
Fetch the next digit (9) from the dividend, attach it to 673 and continue: 6739 / 773

Let's proceed to step 5:
6739 divided by 773 is 8 with a remainder of 555.
The next digit of our result is 8. 
Result so far: 58.0
If we take 6184 away from 6739, we end up with 555.
Bring next digit (0) of the dividend behind the 555 and repeat the process: 5550 / 773

Going ahead to step 6:
The number 773 fits into 5550 7 times, leaving a remainder of 139.
Write down 7 as next digit of the result. 
Result so far: 587.0
The remainder is 139 after subtracting 5411 from 5550.
Include the next digit (6) from the dividend after 139, then repeat: 1396 / 773

Step 7:
If we divide 1396 by 773, we get 1 and a remainder of 623.
Put 1 as the next digit of the answer. 
Result so far: 5871.0
The remainder is 623 after subtracting 773 from 1396.
Append the next digit (3) from the dividend to 623 and continue with: 6233 / 773

On to step 8:
The number 773 fits into 6233 8 times, leaving a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 58718.0
If we subtract 6184 from 6233, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
773 goes into 490 0 times with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 58718.0
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 10:
773 can be fit into 4900 6 times, resulting in a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 58718.06
Subtract 4638 from 4900 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 11:
773 goes into 2620 3 times with a remainder of 301.
Record the quotient 3 as the next digit in the result. 
Result so far: 58718.063
Subtract 2319 from 2620 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 12:
If we divide 3010 by 773, we get 3 and a remainder of 691.
The next digit of our result is 3. 
Result so far: 58718.0633
If we subtract 2319 from 3010, we get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

The final outcome is 58718.0633, with a leftover of 0.00691.
