79424187 ÷ 663 
We want to figure out the number of times 79424187 can be divided by 663.

Moving on to step 1:
663 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 663

On to step 2:
79 divided by 663 is 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 663

Moving on to step 3:
663 goes into 794 1 times with a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 663 from 794, we get 131.
Bring next digit (2) of the dividend behind the 131 and repeat the process: 1312 / 663

Step 4:
1312 divided by 663 is 1 with a remainder of 649.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 649 after subtracting 663 from 1312.
Fetch the next digit (4) from the dividend, attach it to 649 and continue: 6494 / 663

Going ahead to step 5:
663 goes into 6494 9 times with a remainder of 527.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Deduct 5967 from 6494 and we're left with 527.
Bring next digit (1) of the dividend behind the 527 and repeat the process: 5271 / 663

Step 6:
If we divide 5271 by 663, we get 7 and a remainder of 630.
The next digit of our result is 7. 
Result so far: 1197.0
Deduct 4641 from 5271 and we're left with 630.
Include the next digit (8) from the dividend after 630, then repeat: 6308 / 663

Moving on to step 7:
6308 divided by 663 is 9 with a remainder of 341.
The next digit of our result is 9. 
Result so far: 11979.0
If we take 5967 away from 6308, we end up with 341.
Bring next digit (7) of the dividend behind the 341 and repeat the process: 3417 / 663

Step 8:
663 goes into 3417 5 times with a remainder of 102.
The next digit of our result is 5. 
Result so far: 119795.0
If we take 3315 away from 3417, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
When dividing 1020 by 663, we get 1 with a remainder of 357.
Use 1 as the next digit of our solution. 
Result so far: 119795.1
The remainder is 357 after subtracting 663 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Let's proceed to step 10:
If we divide 3570 by 663, we get 5 and a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 119795.15
Deduct 3315 from 3570 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 11:
663 can be fit into 2550 3 times, resulting in a remainder of 561.
Record the quotient 3 as the next digit in the result. 
Result so far: 119795.153
Subtract 1989 from 2550 to get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 12:
If we divide 5610 by 663, we get 8 and a remainder of 306.
Use 8 as the next digit of our solution. 
Result so far: 119795.1538
Subtracting 5304 from 5610 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 13:
The number 663 fits into 3060 4 times, leaving a remainder of 408.
The number 4 becomes the next digit in our result. 
Result so far: 119795.15384
The remainder is 408 after subtracting 2652 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 14:
4080 divided by 663 is 6 with a remainder of 102.
The next digit of our result is 6. 
Result so far: 119795.153846
Deduct 3978 from 4080 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 15:
When dividing 1020 by 663, we get 1 with a remainder of 357.
The next digit of our result is 1. 
Result so far: 119795.1538461
If we subtract 663 from 1020, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 16:
When dividing 3570 by 663, we get 5 with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 119795.15384615
The remainder is 255 after subtracting 3315 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

After the division, we end up with 119795.15384615 and a remainder of 2.55e-07.
