35123962 divided by 809 
Let's see how many times 809 fits into 35123962.

On to step 1:
3 divided by 809 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 809

On to step 2:
35 divided by 809 is 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 809

On to step 3:
351 divided by 809 is 0 with a remainder of 351.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 351 to get 351.
Grab the next digit (2) from the dividend, add it to 351, then carry on: 3512 / 809

Going ahead to step 4:
809 goes into 3512 4 times with a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3236 from 3512 and we're left with 276.
Fetch the next digit (3) from the dividend, attach it to 276 and continue: 2763 / 809

Moving on to step 5:
When dividing 2763 by 809, we get 3 with a remainder of 336.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 2427 from 2763, we get 336.
Take the next digit (9) from the dividend and append it to 336, then repeat: 3369 / 809

Step 6:
809 can be fit into 3369 4 times, resulting in a remainder of 133.
The next digit of our result is 4. 
Result so far: 434.0
If we take 3236 away from 3369, we end up with 133.
Fetch the next digit (6) from the dividend, attach it to 133 and continue: 1336 / 809

Going ahead to step 7:
If we divide 1336 by 809, we get 1 and a remainder of 527.
Put 1 as the next digit of the answer. 
Result so far: 4341.0
Subtracting 809 from 1336 leaves us with 527.
Fetch the next digit (2) from the dividend, attach it to 527 and continue: 5272 / 809

Let's proceed to step 8:
809 goes into 5272 6 times with a remainder of 418.
The number 6 becomes the next digit in our result. 
Result so far: 43416.0
Deduct 4854 from 5272 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 9:
4180 divided by 809 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 43416.5
Subtract 4045 from 4180 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
When dividing 1350 by 809, we get 1 with a remainder of 541.
The number 1 becomes the next digit in our result. 
Result so far: 43416.51
The remainder is 541 after subtracting 809 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Advancing to step 11:
The number 809 fits into 5410 6 times, leaving a remainder of 556.
Use 6 as the next digit of our solution. 
Result so far: 43416.516
The remainder is 556 after subtracting 4854 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 12:
The number 809 fits into 5560 6 times, leaving a remainder of 706.
Put 6 as the next digit of the answer. 
Result so far: 43416.5166
Subtracting 4854 from 5560 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

After the division, we end up with 43416.5166 and a remainder of 0.00706.
