Let's see how many times 535 fits into 80904357.

Going ahead to step 1:
8 divided by 535 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 535

On to step 2:
80 divided by 535 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 535

Step 3:
535 can be fit into 809 1 times, resulting in a remainder of 274.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 535 from 809 and we're left with 274.
Grab the next digit (0) from the dividend, add it to 274, then carry on: 2740 / 535

Going ahead to step 4:
2740 divided by 535 is 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2675 from 2740 and we're left with 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 535

Going ahead to step 5:
654 divided by 535 is 1 with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 151.0
The remainder is 119 after subtracting 535 from 654.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 535

Advancing to step 6:
1193 divided by 535 is 2 with a remainder of 123.
The next digit of our result is 2. 
Result so far: 1512.0
Deduct 1070 from 1193 and we're left with 123.
Fetch the next digit (5) from the dividend, attach it to 123 and continue: 1235 / 535

Let's proceed to step 7:
When dividing 1235 by 535, we get 2 with a remainder of 165.
Write down 2 as next digit of the result. 
Result so far: 15122.0
If we take 1070 away from 1235, we end up with 165.
Append the next digit (7) from the dividend to 165 and continue with: 1657 / 535

On to step 8:
The number 535 fits into 1657 3 times, leaving a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 151223.0
Subtract 1605 from 1657 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
If we divide 520 by 535, we get 0 and a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 151223.0
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
535 can be fit into 5200 9 times, resulting in a remainder of 385.
The number 9 becomes the next digit in our result. 
Result so far: 151223.09
If we take 4815 away from 5200, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 11:
535 can be fit into 3850 7 times, resulting in a remainder of 105.
Write down 7 as next digit of the result. 
Result so far: 151223.097
If we subtract 3745 from 3850, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 12:
535 goes into 1050 1 times with a remainder of 515.
Put 1 as the next digit of the answer. 
Result so far: 151223.0971
If we take 535 away from 1050, we end up with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 13:
The number 535 fits into 5150 9 times, leaving a remainder of 335.
The number 9 becomes the next digit in our result. 
Result so far: 151223.09719
If we subtract 4815 from 5150, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 14:
535 goes into 3350 6 times with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 151223.097196
Subtract 3210 from 3350 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
535 can be fit into 1400 2 times, resulting in a remainder of 330.
The number 2 becomes the next digit in our result. 
Result so far: 151223.0971962
If we subtract 1070 from 1400, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 16:
3300 divided by 535 is 6 with a remainder of 90.
The next digit of our result is 6. 
Result so far: 151223.09719626
Subtracting 3210 from 3300 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 151223.09719626 and a remainder of 9e-08.
