91403747 ÷ 809 
We're looking to find how many times 809 goes into 91403747.

Going ahead to step 1:
The number 809 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 809

Let's proceed to step 2:
809 can be fit into 91 0 times, resulting in a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 809

Step 3:
If we divide 914 by 809, we get 1 and a remainder of 105.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 809 from 914 and we're left with 105.
Include the next digit (0) from the dividend after 105, then repeat: 1050 / 809

Going ahead to step 4:
When dividing 1050 by 809, we get 1 with a remainder of 241.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 809 from 1050, we get 241.
Append the next digit (3) from the dividend to 241 and continue with: 2413 / 809

Let's proceed to step 5:
809 goes into 2413 2 times with a remainder of 795.
The number 2 becomes the next digit in our result. 
Result so far: 112.0
The remainder is 795 after subtracting 1618 from 2413.
Include the next digit (7) from the dividend after 795, then repeat: 7957 / 809

Moving on to step 6:
809 goes into 7957 9 times with a remainder of 676.
The next digit of our result is 9. 
Result so far: 1129.0
The remainder is 676 after subtracting 7281 from 7957.
Take the next digit (4) from the dividend and append it to 676, then repeat: 6764 / 809

On to step 7:
The number 809 fits into 6764 8 times, leaving a remainder of 292.
The next digit of our result is 8. 
Result so far: 11298.0
If we subtract 6472 from 6764, we get 292.
Append the next digit (7) from the dividend to 292 and continue with: 2927 / 809

Advancing to step 8:
2927 divided by 809 is 3 with a remainder of 500.
The next digit of our result is 3. 
Result so far: 112983.0
Deduct 2427 from 2927 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 9:
When dividing 5000 by 809, we get 6 with a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 112983.6
If we take 4854 away from 5000, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
809 goes into 1460 1 times with a remainder of 651.
Use 1 as the next digit of our solution. 
Result so far: 112983.61
Deduct 809 from 1460 and we're left with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Advancing to step 11:
6510 divided by 809 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 112983.618
If we subtract 6472 from 6510, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
The number 809 fits into 380 0 times, leaving a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 112983.618
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 13:
3800 divided by 809 is 4 with a remainder of 564.
Use 4 as the next digit of our solution. 
Result so far: 112983.61804
If we subtract 3236 from 3800, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 14:
The number 809 fits into 5640 6 times, leaving a remainder of 786.
The number 6 becomes the next digit in our result. 
Result so far: 112983.618046
Subtracting 4854 from 5640 leaves us with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Step 15:
7860 divided by 809 is 9 with a remainder of 579.
Put 9 as the next digit of the answer. 
Result so far: 112983.6180469
The remainder is 579 after subtracting 7281 from 7860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 16:
If we divide 5790 by 809, we get 7 and a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 112983.61804697
Subtracting 5663 from 5790 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

After the division, we end up with 112983.61804697 and a remainder of 1.27e-07.
