We look at the division of 77236553 by 775 
Our goal is to divide 77236553 by 775.

Advancing to step 1:
The number 775 fits into 7 0 times, leaving 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 / 775

On to step 2:
77 divided by 775 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 775

On to step 3:
When dividing 772 by 775, we get 0 with a remainder of 772.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 772 leaves us with 772.
Append the next digit (3) from the dividend to 772 and continue with: 7723 / 775

On to step 4:
If we divide 7723 by 775, we get 9 and a remainder of 748.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 6975 from 7723 leaves us with 748.
Append the next digit (6) from the dividend to 748 and continue with: 7486 / 775

Step 5:
When dividing 7486 by 775, we get 9 with a remainder of 511.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 6975 from 7486, we get 511.
Grab the next digit (5) from the dividend, add it to 511, then carry on: 5115 / 775

Step 6:
If we divide 5115 by 775, we get 6 and a remainder of 465.
Write down 6 as next digit of the result. 
Result so far: 996.0
If we take 4650 away from 5115, we end up with 465.
Grab the next digit (5) from the dividend, add it to 465, then carry on: 4655 / 775

Moving on to step 7:
775 can be fit into 4655 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 9966.0
Subtracting 4650 from 4655 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 775

Moving on to step 8:
When dividing 53 by 775, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 99660.0
Subtracting 0 from 53 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
530 divided by 775 is 0 with a remainder of 530.
Write down 0 as next digit of the result. 
Result so far: 99660.0
The remainder is 530 after subtracting 0 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 10:
775 can be fit into 5300 6 times, resulting in a remainder of 650.
The number 6 becomes the next digit in our result. 
Result so far: 99660.06
The remainder is 650 after subtracting 4650 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 11:
775 can be fit into 6500 8 times, resulting in a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 99660.068
Deduct 6200 from 6500 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
If we divide 3000 by 775, we get 3 and a remainder of 675.
Put 3 as the next digit of the answer. 
Result so far: 99660.0683
Deduct 2325 from 3000 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 13:
775 can be fit into 6750 8 times, resulting in a remainder of 550.
The number 8 becomes the next digit in our result. 
Result so far: 99660.06838
Subtract 6200 from 6750 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 14:
If we divide 5500 by 775, we get 7 and a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 99660.068387
Subtract 5425 from 5500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 15:
When dividing 750 by 775, we get 0 with a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 99660.068387
If we take 0 away from 750, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 16:
775 goes into 7500 9 times with a remainder of 525.
Record the quotient 9 as the next digit in the result. 
Result so far: 99660.06838709
Deduct 6975 from 7500 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

The quotient of the division is 99660.06838709, and the remainder is 5.25e-07.
