We're dividing 35815085 by 850 
We're looking to find how many times 850 goes into 35815085.

Let's proceed to step 1:
When dividing 3 by 850, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 850

Let's proceed to step 2:
The number 850 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 850

Advancing to step 3:
850 can be fit into 358 0 times, resulting in a remainder of 358.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 358 and we're left with 358.
Bring next digit (1) of the dividend behind the 358 and repeat the process: 3581 / 850

Step 4:
850 goes into 3581 4 times with a remainder of 181.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3400 from 3581 and we're left with 181.
Append the next digit (5) from the dividend to 181 and continue with: 1815 / 850

Step 5:
If we divide 1815 by 850, we get 2 and a remainder of 115.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 1700 from 1815, we get 115.
Fetch the next digit (0) from the dividend, attach it to 115 and continue: 1150 / 850

Moving on to step 6:
850 can be fit into 1150 1 times, resulting in a remainder of 300.
Put 1 as the next digit of the answer. 
Result so far: 421.0
Subtracting 850 from 1150 leaves us with 300.
Bring next digit (8) of the dividend behind the 300 and repeat the process: 3008 / 850

Moving on to step 7:
850 can be fit into 3008 3 times, resulting in a remainder of 458.
Write down 3 as next digit of the result. 
Result so far: 4213.0
Subtracting 2550 from 3008 leaves us with 458.
Take the next digit (5) from the dividend and append it to 458, then repeat: 4585 / 850

On to step 8:
850 goes into 4585 5 times with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 42135.0
The remainder is 335 after subtracting 4250 from 4585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 9:
If we divide 3350 by 850, we get 3 and a remainder of 800.
Record the quotient 3 as the next digit in the result. 
Result so far: 42135.3
If we subtract 2550 from 3350, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 10:
8000 divided by 850 is 9 with a remainder of 350.
Put 9 as the next digit of the answer. 
Result so far: 42135.39
Subtracting 7650 from 8000 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 11:
The number 850 fits into 3500 4 times, leaving a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 42135.394
Subtract 3400 from 3500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
The number 850 fits into 1000 1 times, leaving a remainder of 150.
Write down 1 as next digit of the result. 
Result so far: 42135.3941
Deduct 850 from 1000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 13:
If we divide 1500 by 850, we get 1 and a remainder of 650.
The next digit of our result is 1. 
Result so far: 42135.39411
If we subtract 850 from 1500, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

After the division, we end up with 42135.39411 and a remainder of 0.00065.
