81363887 divided by 98 
Our goal is to divide 81363887 by 98.

Moving on to step 1:
The number 98 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 98

Let's proceed to step 2:
When dividing 81 by 98, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 98

Step 3:
When dividing 813 by 98, we get 8 with a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 784 from 813 to get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 98

Let's proceed to step 4:
296 divided by 98 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtract 294 from 296 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 98

Going ahead to step 5:
When dividing 23 by 98, we get 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 830.0
Subtract 0 from 23 to get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 98

Going ahead to step 6:
98 goes into 238 2 times with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 8302.0
Subtracting 196 from 238 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 98

On to step 7:
428 divided by 98 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 83024.0
Deduct 392 from 428 and we're left with 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 98

Step 8:
98 goes into 367 3 times with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 830243.0
If we subtract 294 from 367, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
730 divided by 98 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 830243.7
Subtract 686 from 730 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
When dividing 440 by 98, we get 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 830243.74
If we subtract 392 from 440, we 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.

Let's proceed to step 11:
98 goes into 480 4 times with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 830243.744
Subtracting 392 from 480 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 830243.744 with a remainder of 0.0088.
