We divide 80391841 by 850
Let's see how many times 850 fits into 80391841.

Advancing to step 1:
The number 850 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 850

On to step 2:
80 divided by 850 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 850

Going ahead to step 3:
If we divide 803 by 850, we get 0 and a remainder of 803.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 803 leaves us with 803.
Include the next digit (9) from the dividend after 803, then repeat: 8039 / 850

Advancing to step 4:
850 goes into 8039 9 times with a remainder of 389.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7650 from 8039 to get 389.
Include the next digit (1) from the dividend after 389, then repeat: 3891 / 850

Step 5:
850 goes into 3891 4 times with a remainder of 491.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 3400 from 3891 leaves us with 491.
Take the next digit (8) from the dividend and append it to 491, then repeat: 4918 / 850

Moving on to step 6:
If we divide 4918 by 850, we get 5 and a remainder of 668.
Put 5 as the next digit of the answer. 
Result so far: 945.0
Subtract 4250 from 4918 to get 668.
Include the next digit (4) from the dividend after 668, then repeat: 6684 / 850

Moving on to step 7:
850 can be fit into 6684 7 times, resulting in a remainder of 734.
Record the quotient 7 as the next digit in the result. 
Result so far: 9457.0
If we subtract 5950 from 6684, we get 734.
Take the next digit (1) from the dividend and append it to 734, then repeat: 7341 / 850

Step 8:
If we divide 7341 by 850, we get 8 and a remainder of 541.
The number 8 becomes the next digit in our result. 
Result so far: 94578.0
If we take 6800 away from 7341, we end up with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 9:
When dividing 5410 by 850, we get 6 with a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 94578.6
Subtracting 5100 from 5410 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
When dividing 3100 by 850, we get 3 with a remainder of 550.
Write down 3 as next digit of the result. 
Result so far: 94578.63
If we subtract 2550 from 3100, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 11:
The number 850 fits into 5500 6 times, leaving a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 94578.636
Subtract 5100 from 5500 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
4000 divided by 850 is 4 with a remainder of 600.
Put 4 as the next digit of the answer. 
Result so far: 94578.6364
Deduct 3400 from 4000 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 13:
850 can be fit into 6000 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 94578.63647
If we subtract 5950 from 6000, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 14:
If we divide 500 by 850, we get 0 and a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 94578.63647
Deduct 0 from 500 and we're left 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.

Moving on to step 15:
850 can be fit into 5000 5 times, resulting in a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 94578.6364705
Deduct 4250 from 5000 and we're left 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.

On to step 16:
7500 divided by 850 is 8 with a remainder of 700.
The next digit of our result is 8. 
Result so far: 94578.63647058
Subtract 6800 from 7500 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 94578.63647058 with a balance of 7e-07.
