850857 divided by 99 
Our goal is to divide 850857 by 99.

Advancing to step 1:
99 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 99

Going ahead to step 2:
The number 99 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 99

On to step 3:
If we divide 850 by 99, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 792 from 850 and we're left with 58.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 99

Step 4:
99 can be fit into 588 5 times, resulting in a remainder of 93.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 495 away from 588, we end up with 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 99

Step 5:
If we divide 935 by 99, we get 9 and a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Subtracting 891 from 935 leaves us with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 99

Step 6:
447 divided by 99 is 4 with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 8594.0
Subtracting 396 from 447 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.

99 goes into 150 1 times with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 8594.51
If we subtract 99 from 150, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
The number 99 fits into 510 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8594.515
If we subtract 495 from 510, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
99 goes into 150 1 times with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 8594.5151
Subtract 99 from 150 to get 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 11:
99 goes into 510 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 8594.51515
Subtracting 495 from 510 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
99 can be fit into 150 1 times, resulting in a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 8594.515151
Subtracting 99 from 150 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.

Moving on to step 13:
510 divided by 99 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8594.5151515
Subtracting 495 from 510 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
If we divide 150 by 99, we get 1 and a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 8594.51515151
Deduct 99 from 150 and we're left 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.
