636881 ÷ 98 
We're looking to find how many times 98 goes into 636881.

Step 1:
98 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 98

Let's proceed to step 2:
63 divided by 98 is 0 with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 98

Moving on to step 3:
When dividing 636 by 98, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 588 away from 636, we end up with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 98

Moving on to step 4:
The number 98 fits into 488 4 times, leaving a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 96 after subtracting 392 from 488.
Include the next digit (8) from the dividend after 96, then repeat: 968 / 98

On to step 5:
The number 98 fits into 968 9 times, leaving a remainder of 86.
The next digit of our result is 9. 
Result so far: 649.0
The remainder is 86 after subtracting 882 from 968.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 98

On to step 6:
98 goes into 861 8 times with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 6498.0
Subtracting 784 from 861 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 7:
98 can be fit into 770 7 times, resulting in a remainder of 84.
The next digit of our result is 7. 
Result so far: 6498.7
Subtract 686 from 770 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
98 can be fit into 840 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 6498.78
If we take 784 away from 840, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
The number 98 fits into 560 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 6498.785
If we subtract 490 from 560, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
When dividing 700 by 98, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 6498.7857
Deduct 686 from 700 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
If we divide 140 by 98, we get 1 and a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 6498.78571
Subtract 98 from 140 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
98 goes into 420 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 6498.785714
Subtract 392 from 420 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 98 is 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 6498.7857142
If we subtract 196 from 280, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 14:
The number 98 fits into 840 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 6498.78571428
Subtracting 784 from 840 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 6498.78571428, with a leftover of 5.6e-08.
