Let's divide 97539891 by 809
Let's see how many times 809 fits into 97539891.

Going ahead to step 1:
809 goes into 9 0 times with 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.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 809

Step 2:
When dividing 97 by 809, we get 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Include the next digit (5) from the dividend after 97, then repeat: 975 / 809

Going ahead to step 3:
The number 809 fits into 975 1 times, leaving a remainder of 166.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 166 after subtracting 809 from 975.
Grab the next digit (3) from the dividend, add it to 166, then carry on: 1663 / 809

On to step 4:
809 can be fit into 1663 2 times, resulting in a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1618 away from 1663, we end up with 45.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 809

Moving on to step 5:
If we divide 459 by 809, we get 0 and a remainder of 459.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 459, we get 459.
Grab the next digit (8) from the dividend, add it to 459, then carry on: 4598 / 809

Going ahead to step 6:
When dividing 4598 by 809, we get 5 with a remainder of 553.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
The remainder is 553 after subtracting 4045 from 4598.
Grab the next digit (9) from the dividend, add it to 553, then carry on: 5539 / 809

Let's proceed to step 7:
5539 divided by 809 is 6 with a remainder of 685.
Write down 6 as next digit of the result. 
Result so far: 12056.0
Deduct 4854 from 5539 and we're left with 685.
Append the next digit (1) from the dividend to 685 and continue with: 6851 / 809

Moving on to step 8:
When dividing 6851 by 809, we get 8 with a remainder of 379.
Write down 8 as next digit of the result. 
Result so far: 120568.0
If we take 6472 away from 6851, we end up 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.

Moving on to step 9:
3790 divided by 809 is 4 with a remainder of 554.
Record the quotient 4 as the next digit in the result. 
Result so far: 120568.4
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.

Going ahead to step 10:
5540 divided by 809 is 6 with a remainder of 686.
Put 6 as the next digit of the answer. 
Result so far: 120568.46
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.

Advancing to step 11:
If we divide 6860 by 809, we get 8 and a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 120568.468
Deduct 6472 from 6860 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 12:
The number 809 fits into 3880 4 times, leaving a remainder of 644.
Write down 4 as next digit of the result. 
Result so far: 120568.4684
Subtracting 3236 from 3880 leaves us 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.

Moving on to step 13:
6440 divided by 809 is 7 with a remainder of 777.
Record the quotient 7 as the next digit in the result. 
Result so far: 120568.46847
Subtract 5663 from 6440 to get 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 14:
809 can be fit into 7770 9 times, resulting in a remainder of 489.
The number 9 becomes the next digit in our result. 
Result so far: 120568.468479
If we take 7281 away from 7770, we end up with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 15:
When dividing 4890 by 809, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 120568.4684796
Deduct 4854 from 4890 and we're left 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.

Let's proceed to step 16:
When dividing 360 by 809, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 120568.4684796
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 120568.4684796, and the remainder is 3.6e-07.
