We're dividing 10389061 by 802 
Let's see how many times 802 fits into 10389061.

Let's proceed to step 1:
802 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 802

Moving on to step 2:
10 divided by 802 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 802

Advancing to step 3:
802 can be fit into 103 0 times, resulting in a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 103 after subtracting 0 from 103.
Take the next digit (8) from the dividend and append it to 103, then repeat: 1038 / 802

Step 4:
802 can be fit into 1038 1 times, resulting in a remainder of 236.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 802 from 1038, we get 236.
Bring next digit (9) of the dividend behind the 236 and repeat the process: 2369 / 802

Advancing to step 5:
When dividing 2369 by 802, we get 2 with a remainder of 765.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1604 from 2369, we get 765.
Grab the next digit (0) from the dividend, add it to 765, then carry on: 7650 / 802

Going ahead to step 6:
When dividing 7650 by 802, we get 9 with a remainder of 432.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 7218 from 7650 to get 432.
Take the next digit (6) from the dividend and append it to 432, then repeat: 4326 / 802

Going ahead to step 7:
802 can be fit into 4326 5 times, resulting in a remainder of 316.
Record the quotient 5 as the next digit in the result. 
Result so far: 1295.0
The remainder is 316 after subtracting 4010 from 4326.
Take the next digit (1) from the dividend and append it to 316, then repeat: 3161 / 802

On to step 8:
3161 divided by 802 is 3 with a remainder of 755.
Use 3 as the next digit of our solution. 
Result so far: 12953.0
If we take 2406 away from 3161, we end up with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Moving on to step 9:
802 goes into 7550 9 times with a remainder of 332.
Write down 9 as next digit of the result. 
Result so far: 12953.9
Subtracting 7218 from 7550 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 10:
When dividing 3320 by 802, we get 4 with a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 12953.94
Subtract 3208 from 3320 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
802 goes into 1120 1 times with a remainder of 318.
Write down 1 as next digit of the result. 
Result so far: 12953.941
Subtracting 802 from 1120 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 12:
802 goes into 3180 3 times with a remainder of 774.
Write down 3 as next digit of the result. 
Result so far: 12953.9413
The remainder is 774 after subtracting 2406 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 13:
802 goes into 7740 9 times with a remainder of 522.
The next digit of our result is 9. 
Result so far: 12953.94139
If we subtract 7218 from 7740, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 14:
If we divide 5220 by 802, we get 6 and a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 12953.941396
If we take 4812 away from 5220, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 15:
802 goes into 4080 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 12953.9413965
If we take 4010 away from 4080, we end up with 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 16:
700 divided by 802 is 0 with a remainder of 700.
The next digit of our result is 0. 
Result so far: 12953.9413965
If we take 0 away from 700, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 12953.9413965, with a leftover of 7e-07.
