We're dividing 80780885 by 638 
Let's see how many times 638 fits into 80780885.

On to step 1:
8 divided by 638 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 638

Moving on to step 2:
638 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 638

Moving on to step 3:
If we divide 807 by 638, we get 1 and a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 638 from 807 leaves us with 169.
Bring next digit (8) of the dividend behind the 169 and repeat the process: 1698 / 638

Advancing to step 4:
638 goes into 1698 2 times with a remainder of 422.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1276 from 1698 and we're left with 422.
Grab the next digit (0) from the dividend, add it to 422, then carry on: 4220 / 638

Advancing to step 5:
638 goes into 4220 6 times with a remainder of 392.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 3828 from 4220 and we're left with 392.
Append the next digit (8) from the dividend to 392 and continue with: 3928 / 638

Advancing to step 6:
638 can be fit into 3928 6 times, resulting in a remainder of 100.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
Subtract 3828 from 3928 to get 100.
Bring next digit (8) of the dividend behind the 100 and repeat the process: 1008 / 638

Moving on to step 7:
When dividing 1008 by 638, we get 1 with a remainder of 370.
Record the quotient 1 as the next digit in the result. 
Result so far: 12661.0
The remainder is 370 after subtracting 638 from 1008.
Include the next digit (5) from the dividend after 370, then repeat: 3705 / 638

Advancing to step 8:
638 can be fit into 3705 5 times, resulting in a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 126615.0
If we subtract 3190 from 3705, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 9:
638 can be fit into 5150 8 times, resulting in a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 126615.8
Subtracting 5104 from 5150 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
638 can be fit into 460 0 times, resulting in a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 126615.8
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
638 can be fit into 4600 7 times, resulting in a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 126615.807
If we take 4466 away from 4600, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 12:
1340 divided by 638 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 126615.8072
Deduct 1276 from 1340 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
The number 638 fits into 640 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 126615.80721
The remainder is 2 after subtracting 638 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
638 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 126615.80721
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
638 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 126615.80721
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 126615.80721 and a remainder of 2e-06.
