Let's divide 8639099 by 230
Let's see how many times 230 fits into 8639099.

Going ahead to step 1:
When dividing 8 by 230, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 230

Step 2:
86 divided by 230 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 230

Advancing to step 3:
If we divide 863 by 230, we get 3 and a remainder of 173.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 690 from 863 and we're left with 173.
Grab the next digit (9) from the dividend, add it to 173, then carry on: 1739 / 230

Going ahead to step 4:
The number 230 fits into 1739 7 times, leaving a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 1610 from 1739, we get 129.
Grab the next digit (0) from the dividend, add it to 129, then carry on: 1290 / 230

On to step 5:
When dividing 1290 by 230, we get 5 with a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 375.0
If we take 1150 away from 1290, we end up with 140.
Include the next digit (9) from the dividend after 140, then repeat: 1409 / 230

On to step 6:
1409 divided by 230 is 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 3756.0
Subtracting 1380 from 1409 leaves us with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 230

Advancing to step 7:
230 can be fit into 299 1 times, resulting in a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 37561.0
If we subtract 230 from 299, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 8:
230 can be fit into 690 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 37561.3
Deduct 690 from 690 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 230, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 37561.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
230 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37561.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 37561.3, and the remainder is 0.0.
