We look at the division of 859869 by 99 
We're looking to find how many times 99 goes into 859869.

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
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 99

Advancing to step 2:
99 can be fit into 85 0 times, resulting in 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.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 99

Let's proceed to step 3:
If we divide 859 by 99, we get 8 and a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 792 from 859 and we're left with 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 99

Going ahead to step 4:
When dividing 678 by 99, we get 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtract 594 from 678 to get 84.
Bring next digit (6) of the dividend behind the 84 and repeat the process: 846 / 99

Let's proceed to step 5:
When dividing 846 by 99, we get 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 868.0
Subtract 792 from 846 to get 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 99

Step 6:
The number 99 fits into 549 5 times, leaving a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 8685.0
If we subtract 495 from 549, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 8685.5
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
99 can be fit into 450 4 times, resulting in a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 8685.54
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
99 goes into 540 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8685.545
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
450 divided by 99 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 8685.5454
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
99 can be fit into 540 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 8685.54545
Subtract 495 from 540 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
99 goes into 450 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 8685.545454
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 8685.5454545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
99 goes into 450 4 times with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 8685.54545454
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 8685.54545454, and the remainder is 5.4e-08.
