801945 ÷ 99 
We're looking to find how many times 99 goes into 801945.

Advancing to step 1:
When dividing 8 by 99, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 99

On to step 2:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 99

Going ahead to step 3:
The number 99 fits into 801 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 792 from 801 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 99

Let's proceed to step 4:
99 goes into 99 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 81.0
If we take 99 away from 99, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 99

On to step 5:
4 divided by 99 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 810.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 99

Let's proceed to step 6:
If we divide 45 by 99, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 8100.0
The remainder is 45 after subtracting 0 from 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 7:
99 goes into 450 4 times with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 8100.4
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.

Step 8:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8100.45
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.

Advancing to step 9:
When dividing 450 by 99, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 8100.454
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.

Advancing to step 10:
540 divided by 99 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 8100.4545
Deduct 495 from 540 and we're left 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 11:
450 divided by 99 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 8100.45454
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.

Moving on to step 12:
540 divided by 99 is 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 8100.454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
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: 8100.4545454
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 14:
540 divided by 99 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 8100.45454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 8100.45454545 and a remainder of 4.5e-08.
