We're dividing 19889055 by 879 
We're looking to find how many times 879 goes into 19889055.

Moving on to step 1:
879 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 879

Advancing to step 2:
879 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 879

Moving on to step 3:
879 goes into 198 0 times with a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 198, we end up with 198.
Grab the next digit (8) from the dividend, add it to 198, then carry on: 1988 / 879

Advancing to step 4:
1988 divided by 879 is 2 with a remainder of 230.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1758 from 1988 and we're left with 230.
Take the next digit (9) from the dividend and append it to 230, then repeat: 2309 / 879

Let's proceed to step 5:
879 goes into 2309 2 times with a remainder of 551.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1758 from 2309 to get 551.
Fetch the next digit (0) from the dividend, attach it to 551 and continue: 5510 / 879

Moving on to step 6:
5510 divided by 879 is 6 with a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 226.0
Deduct 5274 from 5510 and we're left with 236.
Grab the next digit (5) from the dividend, add it to 236, then carry on: 2365 / 879

On to step 7:
The number 879 fits into 2365 2 times, leaving a remainder of 607.
The number 2 becomes the next digit in our result. 
Result so far: 2262.0
The remainder is 607 after subtracting 1758 from 2365.
Append the next digit (5) from the dividend to 607 and continue with: 6075 / 879

On to step 8:
If we divide 6075 by 879, we get 6 and a remainder of 801.
The number 6 becomes the next digit in our result. 
Result so far: 22626.0
The remainder is 801 after subtracting 5274 from 6075.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Going ahead to step 9:
The number 879 fits into 8010 9 times, leaving a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 22626.9
Subtracting 7911 from 8010 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 10:
879 goes into 990 1 times with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 22626.91
The remainder is 111 after subtracting 879 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 11:
The number 879 fits into 1110 1 times, leaving a remainder of 231.
Record the quotient 1 as the next digit in the result. 
Result so far: 22626.911
If we take 879 away from 1110, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The final outcome is 22626.911, with a leftover of 0.0231.
