We look at the division of 77557090 by 773 
Our goal is to divide 77557090 by 773.

Step 1:
When dividing 7 by 773, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 773

On to step 2:
773 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 773

On to step 3:
773 can be fit into 775 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 773 away from 775, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 773

Let's proceed to step 4:
If we divide 25 by 773, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 25, we end up with 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 773

Advancing to step 5:
773 goes into 257 0 times with a remainder of 257.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we take 0 away from 257, we end up with 257.
Append the next digit (0) from the dividend to 257 and continue with: 2570 / 773

On to step 6:
773 goes into 2570 3 times with a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 1003.0
If we take 2319 away from 2570, we end up with 251.
Bring next digit (9) of the dividend behind the 251 and repeat the process: 2519 / 773

Let's proceed to step 7:
773 can be fit into 2519 3 times, resulting in a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 10033.0
Deduct 2319 from 2519 and we're left with 200.
Fetch the next digit (0) from the dividend, attach it to 200 and continue: 2000 / 773

Going ahead to step 8:
The number 773 fits into 2000 2 times, leaving a remainder of 454.
The number 2 becomes the next digit in our result. 
Result so far: 100332.0
Subtract 1546 from 2000 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 9:
When dividing 4540 by 773, we get 5 with a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 100332.5
The remainder is 675 after subtracting 3865 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 10:
773 can be fit into 6750 8 times, resulting in a remainder of 566.
Record the quotient 8 as the next digit in the result. 
Result so far: 100332.58
If we take 6184 away from 6750, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 11:
When dividing 5660 by 773, we get 7 with a remainder of 249.
Write down 7 as next digit of the result. 
Result so far: 100332.587
The remainder is 249 after subtracting 5411 from 5660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 12:
773 can be fit into 2490 3 times, resulting in a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 100332.5873
If we subtract 2319 from 2490, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 13:
If we divide 1710 by 773, we get 2 and a remainder of 164.
The next digit of our result is 2. 
Result so far: 100332.58732
Subtracting 1546 from 1710 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 14:
The number 773 fits into 1640 2 times, leaving a remainder of 94.
Put 2 as the next digit of the answer. 
Result so far: 100332.587322
Subtract 1546 from 1640 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 100332.587322 with a remainder of 9.4e-06.
