87691947 divided by 809 
We're looking to find how many times 809 goes into 87691947.

On to step 1:
809 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 809

Going ahead to step 2:
87 divided by 809 is 0 with a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 809

Going ahead to step 3:
809 goes into 876 1 times with a remainder of 67.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 809 from 876 leaves us with 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 809

Let's proceed to step 4:
809 goes into 679 0 times with a remainder of 679.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 679 after subtracting 0 from 679.
Append the next digit (1) from the dividend to 679 and continue with: 6791 / 809

Let's proceed to step 5:
When dividing 6791 by 809, we get 8 with a remainder of 319.
Write down 8 as next digit of the result. 
Result so far: 108.0
Deduct 6472 from 6791 and we're left with 319.
Take the next digit (9) from the dividend and append it to 319, then repeat: 3199 / 809

Step 6:
If we divide 3199 by 809, we get 3 and a remainder of 772.
Use 3 as the next digit of our solution. 
Result so far: 1083.0
Subtracting 2427 from 3199 leaves us with 772.
Grab the next digit (4) from the dividend, add it to 772, then carry on: 7724 / 809

Going ahead to step 7:
If we divide 7724 by 809, we get 9 and a remainder of 443.
Use 9 as the next digit of our solution. 
Result so far: 10839.0
If we take 7281 away from 7724, we end up with 443.
Append the next digit (7) from the dividend to 443 and continue with: 4437 / 809

Step 8:
4437 divided by 809 is 5 with a remainder of 392.
Record the quotient 5 as the next digit in the result. 
Result so far: 108395.0
If we take 4045 away from 4437, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 9:
3920 divided by 809 is 4 with a remainder of 684.
Use 4 as the next digit of our solution. 
Result so far: 108395.4
Subtract 3236 from 3920 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Going ahead to step 10:
The number 809 fits into 6840 8 times, leaving a remainder of 368.
Write down 8 as next digit of the result. 
Result so far: 108395.48
If we subtract 6472 from 6840, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 11:
809 goes into 3680 4 times with a remainder of 444.
Put 4 as the next digit of the answer. 
Result so far: 108395.484
If we take 3236 away from 3680, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 12:
When dividing 4440 by 809, we get 5 with a remainder of 395.
Record the quotient 5 as the next digit in the result. 
Result so far: 108395.4845
If we subtract 4045 from 4440, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 13:
809 can be fit into 3950 4 times, resulting in a remainder of 714.
Write down 4 as next digit of the result. 
Result so far: 108395.48454
If we take 3236 away from 3950, we end up with 714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

Going ahead to step 14:
809 goes into 7140 8 times with a remainder of 668.
Use 8 as the next digit of our solution. 
Result so far: 108395.484548
Subtracting 6472 from 7140 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Advancing to step 15:
6680 divided by 809 is 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 108395.4845488
If we take 6472 away from 6680, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 108395.4845488 and a remainder of 2.08e-06.
