We divide 98139389 by 638
Let's see how many times 638 fits into 98139389.

Moving on to step 1:
If we divide 9 by 638, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 638

Step 2:
When dividing 98 by 638, we get 0 with a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 638

Moving on to step 3:
The number 638 fits into 981 1 times, leaving a remainder of 343.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 638 from 981 to get 343.
Include the next digit (3) from the dividend after 343, then repeat: 3433 / 638

Step 4:
The number 638 fits into 3433 5 times, leaving a remainder of 243.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 243 after subtracting 3190 from 3433.
Take the next digit (9) from the dividend and append it to 243, then repeat: 2439 / 638

Advancing to step 5:
When dividing 2439 by 638, we get 3 with a remainder of 525.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Deduct 1914 from 2439 and we're left with 525.
Bring next digit (3) of the dividend behind the 525 and repeat the process: 5253 / 638

On to step 6:
The number 638 fits into 5253 8 times, leaving a remainder of 149.
Put 8 as the next digit of the answer. 
Result so far: 1538.0
Subtracting 5104 from 5253 leaves us with 149.
Include the next digit (8) from the dividend after 149, then repeat: 1498 / 638

Going ahead to step 7:
When dividing 1498 by 638, we get 2 with a remainder of 222.
The number 2 becomes the next digit in our result. 
Result so far: 15382.0
If we subtract 1276 from 1498, we get 222.
Include the next digit (9) from the dividend after 222, then repeat: 2229 / 638

Moving on to step 8:
The number 638 fits into 2229 3 times, leaving a remainder of 315.
Use 3 as the next digit of our solution. 
Result so far: 153823.0
Deduct 1914 from 2229 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 9:
638 goes into 3150 4 times with a remainder of 598.
Put 4 as the next digit of the answer. 
Result so far: 153823.4
Deduct 2552 from 3150 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 10:
If we divide 5980 by 638, we get 9 and a remainder of 238.
Use 9 as the next digit of our solution. 
Result so far: 153823.49
Subtract 5742 from 5980 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 11:
638 can be fit into 2380 3 times, resulting in a remainder of 466.
The next digit of our result is 3. 
Result so far: 153823.493
Subtract 1914 from 2380 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 12:
4660 divided by 638 is 7 with a remainder of 194.
Put 7 as the next digit of the answer. 
Result so far: 153823.4937
If we take 4466 away from 4660, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 13:
1940 divided by 638 is 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 153823.49373
If we subtract 1914 from 1940, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
If we divide 260 by 638, we get 0 and a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 153823.49373
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 15:
638 can be fit into 2600 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 153823.4937304
Subtract 2552 from 2600 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
The number 638 fits into 480 0 times, leaving a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 153823.4937304
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 153823.4937304 with a remaining 4.8e-07.
