864461 ÷ 19 
Our goal is to divide 864461 by 19.

Going ahead to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 19

On to step 2:
The number 19 fits into 86 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 76 away from 86, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 19

Let's proceed to step 3:
104 divided by 19 is 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 95 from 104 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 19

Moving on to step 4:
When dividing 94 by 19, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 454.0
If we subtract 76 from 94, we get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 19

On to step 5:
The number 19 fits into 186 9 times, leaving a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 4549.0
Subtract 171 from 186 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 19

Step 6:
19 can be fit into 151 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 45497.0
Subtract 133 from 151 to get 18.
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 7:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 45497.9
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
19 goes into 90 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 45497.94
If we take 76 away from 90, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 19, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 45497.947
Deduct 133 from 140 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
When dividing 70 by 19, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 45497.9473
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 45497.94736
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 19, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 45497.947368
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
19 goes into 80 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 45497.9473684
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 45497.94736842
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 45497.94736842 and a remainder of 2e-09.
