We divide 79227990 by 638
We want to divide 79227990 by 638.

Step 1:
If we divide 7 by 638, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 638

Advancing to step 2:
79 divided by 638 is 0 with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (2) from the dividend and append it to 79, then repeat: 792 / 638

Advancing to step 3:
When dividing 792 by 638, we get 1 with a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 638 from 792, we get 154.
Fetch the next digit (2) from the dividend, attach it to 154 and continue: 1542 / 638

Advancing to step 4:
638 goes into 1542 2 times with a remainder of 266.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1276 from 1542 leaves us with 266.
Fetch the next digit (7) from the dividend, attach it to 266 and continue: 2667 / 638

Advancing to step 5:
638 can be fit into 2667 4 times, resulting in a remainder of 115.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 2552 from 2667 leaves us with 115.
Fetch the next digit (9) from the dividend, attach it to 115 and continue: 1159 / 638

Step 6:
638 goes into 1159 1 times with a remainder of 521.
Put 1 as the next digit of the answer. 
Result so far: 1241.0
The remainder is 521 after subtracting 638 from 1159.
Bring next digit (9) of the dividend behind the 521 and repeat the process: 5219 / 638

Step 7:
If we divide 5219 by 638, we get 8 and a remainder of 115.
Write down 8 as next digit of the result. 
Result so far: 12418.0
Subtracting 5104 from 5219 leaves us with 115.
Bring next digit (0) of the dividend behind the 115 and repeat the process: 1150 / 638

Advancing to step 8:
638 can be fit into 1150 1 times, resulting in a remainder of 512.
Write down 1 as next digit of the result. 
Result so far: 124181.0
Subtract 638 from 1150 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 9:
5120 divided by 638 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 124181.8
Subtracting 5104 from 5120 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
638 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 124181.8
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
638 can be fit into 1600 2 times, resulting in a remainder of 324.
Put 2 as the next digit of the answer. 
Result so far: 124181.802
Subtracting 1276 from 1600 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 12:
When dividing 3240 by 638, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 124181.8025
If we take 3190 away from 3240, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
638 can be fit into 500 0 times, resulting in a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 124181.8025
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
638 can be fit into 5000 7 times, resulting in a remainder of 534.
The next digit of our result is 7. 
Result so far: 124181.802507
Subtracting 4466 from 5000 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 15:
When dividing 5340 by 638, we get 8 with a remainder of 236.
Put 8 as the next digit of the answer. 
Result so far: 124181.8025078
If we take 5104 away from 5340, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 16:
When dividing 2360 by 638, we get 3 with a remainder of 446.
Write down 3 as next digit of the result. 
Result so far: 124181.80250783
If we subtract 1914 from 2360, we get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

The final result is 124181.80250783 with a remainder of 4.46e-07.
