We divide 97668888 by 638
We want to divide 97668888 by 638.

Moving on to step 1:
9 divided by 638 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 638

Advancing to step 2:
The number 638 fits into 97 0 times, leaving a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 638

Advancing to step 3:
638 can be fit into 976 1 times, resulting in a remainder of 338.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 638 from 976, we get 338.
Include the next digit (6) from the dividend after 338, then repeat: 3386 / 638

Step 4:
3386 divided by 638 is 5 with a remainder of 196.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 3190 from 3386 leaves us with 196.
Include the next digit (8) from the dividend after 196, then repeat: 1968 / 638

On to step 5:
638 can be fit into 1968 3 times, resulting in a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
If we subtract 1914 from 1968, we get 54.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 638

On to step 6:
548 divided by 638 is 0 with a remainder of 548.
Put 0 as the next digit of the answer. 
Result so far: 1530.0
Deduct 0 from 548 and we're left with 548.
Bring next digit (8) of the dividend behind the 548 and repeat the process: 5488 / 638

Going ahead to step 7:
638 goes into 5488 8 times with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 15308.0
Subtract 5104 from 5488 to get 384.
Bring next digit (8) of the dividend behind the 384 and repeat the process: 3848 / 638

Step 8:
If we divide 3848 by 638, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 153086.0
If we subtract 3828 from 3848, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
638 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 153086.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
When dividing 2000 by 638, we get 3 with a remainder of 86.
The next digit of our result is 3. 
Result so far: 153086.03
The remainder is 86 after subtracting 1914 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
If we divide 860 by 638, we get 1 and a remainder of 222.
Put 1 as the next digit of the answer. 
Result so far: 153086.031
If we take 638 away from 860, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 12:
638 goes into 2220 3 times with a remainder of 306.
Write down 3 as next digit of the result. 
Result so far: 153086.0313
Deduct 1914 from 2220 and we're left 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.

Let's proceed to step 13:
3060 divided by 638 is 4 with a remainder of 508.
The next digit of our result is 4. 
Result so far: 153086.03134
Subtract 2552 from 3060 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 14:
The number 638 fits into 5080 7 times, leaving a remainder of 614.
The number 7 becomes the next digit in our result. 
Result so far: 153086.031347
If we subtract 4466 from 5080, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Going ahead to step 15:
638 can be fit into 6140 9 times, resulting in a remainder of 398.
Put 9 as the next digit of the answer. 
Result so far: 153086.0313479
The remainder is 398 after subtracting 5742 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 16:
When dividing 3980 by 638, we get 6 with a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 153086.03134796
Subtract 3828 from 3980 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 153086.03134796 with a remainder of 1.52e-07.
