We're dividing 853979 by 99 
Our goal is to divide 853979 by 99.

On to step 1:
99 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 99

Step 2:
The number 99 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 99

Moving on to step 3:
99 goes into 853 8 times with a remainder of 61.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 792 from 853 to get 61.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 99

Step 4:
If we divide 619 by 99, we get 6 and a remainder of 25.
The next digit of our result is 6. 
Result so far: 86.0
If we take 594 away from 619, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 99

Step 5:
257 divided by 99 is 2 with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 862.0
If we take 198 away from 257, we end up with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 99

Advancing to step 6:
The number 99 fits into 599 6 times, leaving a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 8626.0
Subtract 594 from 599 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 99, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8626.0
If we subtract 0 from 50, 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 8:
500 divided by 99 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8626.05
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
If we divide 50 by 99, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 8626.05
If we subtract 0 from 50, 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 10:
If we divide 500 by 99, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8626.0505
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 99, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8626.0505
If we subtract 0 from 50, 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.

On to step 12:
If we divide 500 by 99, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8626.050505
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
99 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8626.050505
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
500 divided by 99 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8626.05050505
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 8626.05050505, with a leftover of 5e-09.
