69863579 divided by 809 
We're looking to find how many times 809 goes into 69863579.

Let's proceed to step 1:
6 divided by 809 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 809

Step 2:
809 can be fit into 69 0 times, resulting in a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 809

Advancing to step 3:
When dividing 698 by 809, we get 0 with a remainder of 698.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 698 leaves us with 698.
Fetch the next digit (6) from the dividend, attach it to 698 and continue: 6986 / 809

Advancing to step 4:
809 can be fit into 6986 8 times, resulting in a remainder of 514.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6472 away from 6986, we end up with 514.
Include the next digit (3) from the dividend after 514, then repeat: 5143 / 809

Let's proceed to step 5:
When dividing 5143 by 809, we get 6 with a remainder of 289.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 4854 away from 5143, we end up with 289.
Take the next digit (5) from the dividend and append it to 289, then repeat: 2895 / 809

Let's proceed to step 6:
809 goes into 2895 3 times with a remainder of 468.
Use 3 as the next digit of our solution. 
Result so far: 863.0
If we take 2427 away from 2895, we end up with 468.
Fetch the next digit (7) from the dividend, attach it to 468 and continue: 4687 / 809

Step 7:
4687 divided by 809 is 5 with a remainder of 642.
Use 5 as the next digit of our solution. 
Result so far: 8635.0
Subtracting 4045 from 4687 leaves us with 642.
Take the next digit (9) from the dividend and append it to 642, then repeat: 6429 / 809

Moving on to step 8:
809 goes into 6429 7 times with a remainder of 766.
The number 7 becomes the next digit in our result. 
Result so far: 86357.0
If we subtract 5663 from 6429, we get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Advancing to step 9:
The number 809 fits into 7660 9 times, leaving a remainder of 379.
Write down 9 as next digit of the result. 
Result so far: 86357.9
Subtracting 7281 from 7660 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 10:
809 can be fit into 3790 4 times, resulting in a remainder of 554.
Use 4 as the next digit of our solution. 
Result so far: 86357.94
The remainder is 554 after subtracting 3236 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Advancing to step 11:
809 can be fit into 5540 6 times, resulting in a remainder of 686.
Put 6 as the next digit of the answer. 
Result so far: 86357.946
The remainder is 686 after subtracting 4854 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 12:
The number 809 fits into 6860 8 times, leaving a remainder of 388.
The number 8 becomes the next digit in our result. 
Result so far: 86357.9468
If we subtract 6472 from 6860, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 13:
809 can be fit into 3880 4 times, resulting in a remainder of 644.
The number 4 becomes the next digit in our result. 
Result so far: 86357.94684
Deduct 3236 from 3880 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Advancing to step 14:
The number 809 fits into 6440 7 times, leaving a remainder of 777.
The number 7 becomes the next digit in our result. 
Result so far: 86357.946847
Deduct 5663 from 6440 and we're left with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Moving on to step 15:
When dividing 7770 by 809, we get 9 with a remainder of 489.
Put 9 as the next digit of the answer. 
Result so far: 86357.9468479
If we subtract 7281 from 7770, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 16:
809 goes into 4890 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 86357.94684796
If we take 4854 away from 4890, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 86357.94684796 with a remainder of 3.6e-08.
