We look at the division of 77569810 by 663 
Our goal is to divide 77569810 by 663.

Step 1:
If we divide 7 by 663, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 663

On to step 2:
When dividing 77 by 663, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 663

Step 3:
663 goes into 775 1 times with a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 663 from 775 and we're left with 112.
Bring next digit (6) of the dividend behind the 112 and repeat the process: 1126 / 663

Let's proceed to step 4:
The number 663 fits into 1126 1 times, leaving a remainder of 463.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 463 after subtracting 663 from 1126.
Bring next digit (9) of the dividend behind the 463 and repeat the process: 4639 / 663

On to step 5:
663 can be fit into 4639 6 times, resulting in a remainder of 661.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
If we subtract 3978 from 4639, we get 661.
Include the next digit (8) from the dividend after 661, then repeat: 6618 / 663

Step 6:
When dividing 6618 by 663, we get 9 with a remainder of 651.
Put 9 as the next digit of the answer. 
Result so far: 1169.0
The remainder is 651 after subtracting 5967 from 6618.
Grab the next digit (1) from the dividend, add it to 651, then carry on: 6511 / 663

Step 7:
6511 divided by 663 is 9 with a remainder of 544.
Record the quotient 9 as the next digit in the result. 
Result so far: 11699.0
If we take 5967 away from 6511, we end up with 544.
Bring next digit (0) of the dividend behind the 544 and repeat the process: 5440 / 663

Step 8:
The number 663 fits into 5440 8 times, leaving a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 116998.0
Subtract 5304 from 5440 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 9:
663 can be fit into 1360 2 times, resulting in a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 116998.2
If we subtract 1326 from 1360, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
340 divided by 663 is 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 116998.2
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
If we divide 3400 by 663, we get 5 and a remainder of 85.
The next digit of our result is 5. 
Result so far: 116998.205
Subtracting 3315 from 3400 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 12:
850 divided by 663 is 1 with a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 116998.2051
The remainder is 187 after subtracting 663 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 13:
If we divide 1870 by 663, we get 2 and a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 116998.20512
Subtracting 1326 from 1870 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 14:
663 can be fit into 5440 8 times, resulting in a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 116998.205128
If we subtract 5304 from 5440, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
1360 divided by 663 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 116998.2051282
Deduct 1326 from 1360 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 16:
The number 663 fits into 340 0 times, leaving a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 116998.2051282
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The quotient of the division is 116998.2051282, and the remainder is 3.4e-07.
