We look at the division of 35438679 by 809 
We're looking to find how many times 809 goes into 35438679.

Advancing to step 1:
809 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 809

On to step 2:
809 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 809

Step 3:
If we divide 354 by 809, we get 0 and a remainder of 354.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 354 after subtracting 0 from 354.
Take the next digit (3) from the dividend and append it to 354, then repeat: 3543 / 809

On to step 4:
3543 divided by 809 is 4 with a remainder of 307.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 3236 from 3543 to get 307.
Grab the next digit (8) from the dividend, add it to 307, then carry on: 3078 / 809

On to step 5:
If we divide 3078 by 809, we get 3 and a remainder of 651.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 2427 from 3078 to get 651.
Take the next digit (6) from the dividend and append it to 651, then repeat: 6516 / 809

Moving on to step 6:
The number 809 fits into 6516 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 438.0
Subtract 6472 from 6516 to get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 809

Moving on to step 7:
When dividing 447 by 809, we get 0 with a remainder of 447.
Write down 0 as next digit of the result. 
Result so far: 4380.0
If we subtract 0 from 447, we get 447.
Bring next digit (9) of the dividend behind the 447 and repeat the process: 4479 / 809

Going ahead to step 8:
809 goes into 4479 5 times with a remainder of 434.
The next digit of our result is 5. 
Result so far: 43805.0
Subtracting 4045 from 4479 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 9:
If we divide 4340 by 809, we get 5 and a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 43805.5
Deduct 4045 from 4340 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 10:
The number 809 fits into 2950 3 times, leaving a remainder of 523.
Use 3 as the next digit of our solution. 
Result so far: 43805.53
If we subtract 2427 from 2950, we get 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 11:
809 can be fit into 5230 6 times, resulting in a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 43805.536
The remainder is 376 after subtracting 4854 from 5230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 12:
If we divide 3760 by 809, we get 4 and a remainder of 524.
The number 4 becomes the next digit in our result. 
Result so far: 43805.5364
If we take 3236 away from 3760, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 13:
If we divide 5240 by 809, we get 6 and a remainder of 386.
The next digit of our result is 6. 
Result so far: 43805.53646
The remainder is 386 after subtracting 4854 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 14:
When dividing 3860 by 809, we get 4 with a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 43805.536464
Subtract 3236 from 3860 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 15:
When dividing 6240 by 809, we get 7 with a remainder of 577.
Use 7 as the next digit of our solution. 
Result so far: 43805.5364647
If we take 5663 away from 6240, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Moving on to step 16:
809 goes into 5770 7 times with a remainder of 107.
The next digit of our result is 7. 
Result so far: 43805.53646477
If we subtract 5663 from 5770, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 43805.53646477 and a remainder of 1.07e-07.
