Let's divide 84839991 by 850
Let's see how many times 850 fits into 84839991.

Step 1:
If we divide 8 by 850, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 850

Moving on to step 2:
If we divide 84 by 850, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 850

On to step 3:
When dividing 848 by 850, we get 0 with a remainder of 848.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 848, we end up with 848.
Take the next digit (3) from the dividend and append it to 848, then repeat: 8483 / 850

Going ahead to step 4:
When dividing 8483 by 850, we get 9 with a remainder of 833.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7650 from 8483 and we're left with 833.
Append the next digit (9) from the dividend to 833 and continue with: 8339 / 850

Advancing to step 5:
The number 850 fits into 8339 9 times, leaving a remainder of 689.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 689 after subtracting 7650 from 8339.
Fetch the next digit (9) from the dividend, attach it to 689 and continue: 6899 / 850

Let's proceed to step 6:
The number 850 fits into 6899 8 times, leaving a remainder of 99.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
If we subtract 6800 from 6899, we get 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 850

Step 7:
If we divide 999 by 850, we get 1 and a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 9981.0
Subtract 850 from 999 to get 149.
Fetch the next digit (1) from the dividend, attach it to 149 and continue: 1491 / 850

Moving on to step 8:
850 can be fit into 1491 1 times, resulting in a remainder of 641.
The number 1 becomes the next digit in our result. 
Result so far: 99811.0
Subtracting 850 from 1491 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Going ahead to step 9:
The number 850 fits into 6410 7 times, leaving a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 99811.7
If we take 5950 away from 6410, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 10:
When dividing 4600 by 850, we get 5 with a remainder of 350.
The next digit of our result is 5. 
Result so far: 99811.75
Deduct 4250 from 4600 and we're left 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.

Moving on to step 11:
850 goes into 3500 4 times with a remainder of 100.
Use 4 as the next digit of our solution. 
Result so far: 99811.754
The remainder is 100 after subtracting 3400 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
850 can be fit into 1000 1 times, resulting in a remainder of 150.
Write down 1 as next digit of the result. 
Result so far: 99811.7541
The remainder is 150 after subtracting 850 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 13:
850 can be fit into 1500 1 times, resulting in a remainder of 650.
The number 1 becomes the next digit in our result. 
Result so far: 99811.75411
The remainder is 650 after subtracting 850 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The quotient of the division is 99811.75411, and the remainder is 0.00065.
