We're dividing 35570857 by 909 
We want to figure out the number of times 35570857 can be divided by 909.

Let's proceed to step 1:
If we divide 3 by 909, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 909

Moving on to step 2:
909 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 909

On to step 3:
909 goes into 355 0 times with a remainder of 355.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 355 to get 355.
Bring next digit (7) of the dividend behind the 355 and repeat the process: 3557 / 909

Going ahead to step 4:
909 can be fit into 3557 3 times, resulting in a remainder of 830.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2727 from 3557 and we're left with 830.
Include the next digit (0) from the dividend after 830, then repeat: 8300 / 909

On to step 5:
The number 909 fits into 8300 9 times, leaving a remainder of 119.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 8181 from 8300, we get 119.
Bring next digit (8) of the dividend behind the 119 and repeat the process: 1198 / 909

Step 6:
1198 divided by 909 is 1 with a remainder of 289.
Use 1 as the next digit of our solution. 
Result so far: 391.0
The remainder is 289 after subtracting 909 from 1198.
Take the next digit (5) from the dividend and append it to 289, then repeat: 2895 / 909

Moving on to step 7:
When dividing 2895 by 909, we get 3 with a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 3913.0
Subtracting 2727 from 2895 leaves us with 168.
Bring next digit (7) of the dividend behind the 168 and repeat the process: 1687 / 909

Moving on to step 8:
If we divide 1687 by 909, we get 1 and a remainder of 778.
The next digit of our result is 1. 
Result so far: 39131.0
Subtract 909 from 1687 to get 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Let's proceed to step 9:
909 goes into 7780 8 times with a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 39131.8
Deduct 7272 from 7780 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 10:
5080 divided by 909 is 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 39131.85
If we subtract 4545 from 5080, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 11:
When dividing 5350 by 909, we get 5 with a remainder of 805.
Record the quotient 5 as the next digit in the result. 
Result so far: 39131.855
If we take 4545 away from 5350, we end up with 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

The quotient of the division is 39131.855, and the remainder is 0.0805.
