35043790 ÷ 809 
We want to figure out the number of times 35043790 can be divided by 809.

Moving on to step 1:
809 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 809

On to step 2:
809 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 809

On to step 3:
809 goes into 350 0 times with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 350, we get 350.
Take the next digit (4) from the dividend and append it to 350, then repeat: 3504 / 809

Step 4:
3504 divided by 809 is 4 with a remainder of 268.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3236 from 3504 to get 268.
Fetch the next digit (3) from the dividend, attach it to 268 and continue: 2683 / 809

Let's proceed to step 5:
The number 809 fits into 2683 3 times, leaving a remainder of 256.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 256 after subtracting 2427 from 2683.
Take the next digit (7) from the dividend and append it to 256, then repeat: 2567 / 809

Step 6:
When dividing 2567 by 809, we get 3 with a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 433.0
Subtract 2427 from 2567 to get 140.
Append the next digit (9) from the dividend to 140 and continue with: 1409 / 809

Moving on to step 7:
809 can be fit into 1409 1 times, resulting in a remainder of 600.
Put 1 as the next digit of the answer. 
Result so far: 4331.0
Subtract 809 from 1409 to get 600.
Bring next digit (0) of the dividend behind the 600 and repeat the process: 6000 / 809

Going ahead to step 8:
809 can be fit into 6000 7 times, resulting in a remainder of 337.
The number 7 becomes the next digit in our result. 
Result so far: 43317.0
The remainder is 337 after subtracting 5663 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 9:
3370 divided by 809 is 4 with a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 43317.4
The remainder is 134 after subtracting 3236 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
The number 809 fits into 1340 1 times, leaving a remainder of 531.
The next digit of our result is 1. 
Result so far: 43317.41
Deduct 809 from 1340 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 11:
5310 divided by 809 is 6 with a remainder of 456.
The next digit of our result is 6. 
Result so far: 43317.416
If we subtract 4854 from 5310, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 12:
The number 809 fits into 4560 5 times, leaving a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 43317.4165
The remainder is 515 after subtracting 4045 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Going ahead to step 13:
5150 divided by 809 is 6 with a remainder of 296.
The next digit of our result is 6. 
Result so far: 43317.41656
If we take 4854 away from 5150, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 14:
If we divide 2960 by 809, we get 3 and a remainder of 533.
Write down 3 as next digit of the result. 
Result so far: 43317.416563
Deduct 2427 from 2960 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 15:
5330 divided by 809 is 6 with a remainder of 476.
The number 6 becomes the next digit in our result. 
Result so far: 43317.4165636
Deduct 4854 from 5330 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 16:
If we divide 4760 by 809, we get 5 and a remainder of 715.
The next digit of our result is 5. 
Result so far: 43317.41656365
If we subtract 4045 from 4760, we get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

After the division, we end up with 43317.41656365 and a remainder of 7.15e-07.
