We're dividing 76780890 by 850 
We're looking to find how many times 850 goes into 76780890.

Let's proceed to step 1:
If we divide 7 by 850, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 850

Let's proceed to step 2:
76 divided by 850 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 850

Advancing to step 3:
767 divided by 850 is 0 with a remainder of 767.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 767 leaves us with 767.
Append the next digit (8) from the dividend to 767 and continue with: 7678 / 850

Step 4:
850 can be fit into 7678 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 7650 from 7678 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 850

Step 5:
850 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 280 to get 280.
Include the next digit (8) from the dividend after 280, then repeat: 2808 / 850

Going ahead to step 6:
When dividing 2808 by 850, we get 3 with a remainder of 258.
Write down 3 as next digit of the result. 
Result so far: 903.0
If we subtract 2550 from 2808, we get 258.
Bring next digit (9) of the dividend behind the 258 and repeat the process: 2589 / 850

Moving on to step 7:
If we divide 2589 by 850, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 9033.0
Subtract 2550 from 2589 to get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 850

Going ahead to step 8:
If we divide 390 by 850, we get 0 and a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 90330.0
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 9:
3900 divided by 850 is 4 with a remainder of 500.
The next digit of our result is 4. 
Result so far: 90330.4
Subtracting 3400 from 3900 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
When dividing 5000 by 850, we get 5 with a remainder of 750.
The next digit of our result is 5. 
Result so far: 90330.45
Subtracting 4250 from 5000 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 11:
The number 850 fits into 7500 8 times, leaving a remainder of 700.
Write down 8 as next digit of the result. 
Result so far: 90330.458
Subtracting 6800 from 7500 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 12:
When dividing 7000 by 850, we get 8 with a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 90330.4588
Subtracting 6800 from 7000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 90330.4588 with a remaining 0.002.
