We look at the division of 30134251 by 850 
We're looking to find how many times 850 goes into 30134251.

Going ahead to step 1:
If we divide 3 by 850, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 850

Going ahead to step 2:
When dividing 30 by 850, 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.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 850

Let's proceed to step 3:
The number 850 fits into 301 0 times, leaving a remainder of 301.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 301 and we're left with 301.
Grab the next digit (3) from the dividend, add it to 301, then carry on: 3013 / 850

Step 4:
850 can be fit into 3013 3 times, resulting in a remainder of 463.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2550 from 3013, we get 463.
Fetch the next digit (4) from the dividend, attach it to 463 and continue: 4634 / 850

Let's proceed to step 5:
When dividing 4634 by 850, we get 5 with a remainder of 384.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 4250 from 4634 leaves us with 384.
Append the next digit (2) from the dividend to 384 and continue with: 3842 / 850

On to step 6:
The number 850 fits into 3842 4 times, leaving a remainder of 442.
The next digit of our result is 4. 
Result so far: 354.0
Subtract 3400 from 3842 to get 442.
Grab the next digit (5) from the dividend, add it to 442, then carry on: 4425 / 850

Advancing to step 7:
4425 divided by 850 is 5 with a remainder of 175.
Put 5 as the next digit of the answer. 
Result so far: 3545.0
Subtracting 4250 from 4425 leaves us with 175.
Grab the next digit (1) from the dividend, add it to 175, then carry on: 1751 / 850

On to step 8:
When dividing 1751 by 850, we get 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 35452.0
Subtracting 1700 from 1751 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
510 divided by 850 is 0 with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 35452.0
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
If we divide 5100 by 850, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 35452.06
Subtracting 5100 from 5100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
850 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35452.06
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
0 divided by 850 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35452.06
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 35452.06 with a balance of 0.0.
