We divide 98689131 by 810
We're looking to find how many times 810 goes into 98689131.

Moving on to step 1:
When dividing 9 by 810, we get 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 (8) from the dividend, add it to 9, then carry on: 98 / 810

Step 2:
If we divide 98 by 810, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 98, we get 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 810

Advancing to step 3:
810 goes into 986 1 times with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 810 from 986 leaves us with 176.
Fetch the next digit (8) from the dividend, attach it to 176 and continue: 1768 / 810

Advancing to step 4:
810 can be fit into 1768 2 times, resulting in a remainder of 148.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1620 from 1768 to get 148.
Include the next digit (9) from the dividend after 148, then repeat: 1489 / 810

On to step 5:
810 goes into 1489 1 times with a remainder of 679.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 810 from 1489 to get 679.
Bring next digit (1) of the dividend behind the 679 and repeat the process: 6791 / 810

Going ahead to step 6:
The number 810 fits into 6791 8 times, leaving a remainder of 311.
Write down 8 as next digit of the result. 
Result so far: 1218.0
If we take 6480 away from 6791, we end up with 311.
Grab the next digit (3) from the dividend, add it to 311, then carry on: 3113 / 810

On to step 7:
3113 divided by 810 is 3 with a remainder of 683.
Put 3 as the next digit of the answer. 
Result so far: 12183.0
Subtracting 2430 from 3113 leaves us with 683.
Fetch the next digit (1) from the dividend, attach it to 683 and continue: 6831 / 810

Advancing to step 8:
810 can be fit into 6831 8 times, resulting in a remainder of 351.
The number 8 becomes the next digit in our result. 
Result so far: 121838.0
Subtracting 6480 from 6831 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 9:
The number 810 fits into 3510 4 times, leaving a remainder of 270.
Write down 4 as next digit of the result. 
Result so far: 121838.4
Deduct 3240 from 3510 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
The number 810 fits into 2700 3 times, leaving a remainder of 270.
Use 3 as the next digit of our solution. 
Result so far: 121838.43
Deduct 2430 from 2700 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 11:
2700 divided by 810 is 3 with a remainder of 270.
Put 3 as the next digit of the answer. 
Result so far: 121838.433
Subtracting 2430 from 2700 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

After the division, we end up with 121838.433 and a remainder of 0.027.
