We look at the division of 879864 by 19 
We want to divide 879864 by 19.

Advancing to step 1:
8 divided by 19 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 19

Advancing to step 2:
The number 19 fits into 87 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 76 from 87 to get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 19

Step 3:
When dividing 119 by 19, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 114 away from 119, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 19

Let's proceed to step 4:
19 goes into 58 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 463.0
If we take 57 away from 58, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 19

Going ahead to step 5:
19 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 4630.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 19

Going ahead to step 6:
The number 19 fits into 164 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 46308.0
If we take 152 away from 164, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 19, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 46308.6
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 46308.63
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 19, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 46308.631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
When dividing 110 by 19, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 46308.6315
If we subtract 95 from 110, 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.

Let's proceed to step 11:
If we divide 150 by 19, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 46308.63157
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 46308.631578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
If we divide 180 by 19, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 46308.6315789
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
90 divided by 19 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 46308.63157894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 46308.63157894, with a leftover of 1.4e-08.
