Let's divide 79390430 by 663
We want to divide 79390430 by 663.

Going ahead to step 1:
When dividing 7 by 663, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 663

Advancing to step 2:
663 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 663

On to step 3:
The number 663 fits into 793 1 times, leaving a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 663 from 793 and we're left with 130.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 663

Step 4:
The number 663 fits into 1309 1 times, leaving a remainder of 646.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 663 from 1309 to get 646.
Grab the next digit (0) from the dividend, add it to 646, then carry on: 6460 / 663

Step 5:
663 can be fit into 6460 9 times, resulting in a remainder of 493.
Use 9 as the next digit of our solution. 
Result so far: 119.0
The remainder is 493 after subtracting 5967 from 6460.
Bring next digit (4) of the dividend behind the 493 and repeat the process: 4934 / 663

Let's proceed to step 6:
If we divide 4934 by 663, we get 7 and a remainder of 293.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
If we subtract 4641 from 4934, we get 293.
Fetch the next digit (3) from the dividend, attach it to 293 and continue: 2933 / 663

Moving on to step 7:
2933 divided by 663 is 4 with a remainder of 281.
Record the quotient 4 as the next digit in the result. 
Result so far: 11974.0
If we take 2652 away from 2933, we end up with 281.
Take the next digit (0) from the dividend and append it to 281, then repeat: 2810 / 663

Step 8:
663 can be fit into 2810 4 times, resulting in a remainder of 158.
The next digit of our result is 4. 
Result so far: 119744.0
Subtract 2652 from 2810 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 9:
1580 divided by 663 is 2 with a remainder of 254.
Use 2 as the next digit of our solution. 
Result so far: 119744.2
Subtract 1326 from 1580 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 10:
If we divide 2540 by 663, we get 3 and a remainder of 551.
The next digit of our result is 3. 
Result so far: 119744.23
The remainder is 551 after subtracting 1989 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Moving on to step 11:
If we divide 5510 by 663, we get 8 and a remainder of 206.
The next digit of our result is 8. 
Result so far: 119744.238
Deduct 5304 from 5510 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 12:
When dividing 2060 by 663, we get 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 119744.2383
Subtract 1989 from 2060 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 13:
When dividing 710 by 663, we get 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 119744.23831
The remainder is 47 after subtracting 663 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 14:
663 goes into 470 0 times with a remainder of 470.
The next digit of our result is 0. 
Result so far: 119744.23831
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 15:
The number 663 fits into 4700 7 times, leaving a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 119744.2383107
The remainder is 59 after subtracting 4641 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 16:
663 can be fit into 590 0 times, resulting in a remainder of 590.
The number 0 becomes the next digit in our result. 
Result so far: 119744.2383107
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final outcome is 119744.2383107, with a leftover of 5.9e-07.
