We look at the division of 307521 by 35 
We want to figure out the number of times 307521 can be divided by 35.

Advancing to step 1:
If we divide 3 by 35, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 35

Moving on to step 2:
When dividing 30 by 35, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 35

Advancing to step 3:
35 goes into 307 8 times with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 280 from 307 leaves us with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 35

Step 4:
When dividing 275 by 35, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 245 away from 275, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 35

Advancing to step 5:
302 divided by 35 is 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 878.0
If we subtract 280 from 302, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 35

Going ahead to step 6:
35 can be fit into 221 6 times, resulting in a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 8786.0
Subtract 210 from 221 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
35 can be fit into 110 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 8786.3
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
35 goes into 50 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 8786.31
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 35 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 8786.314
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 35 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 8786.3142
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
300 divided by 35 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 8786.31428
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 35 fits into 200 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8786.314285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
250 divided by 35 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 8786.3142857
If we take 245 away from 250, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
50 divided by 35 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 8786.31428571
The remainder is 15 after subtracting 35 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 8786.31428571 with a remainder of 1.5e-08.
