19897386 divided by 478 
We're looking to find how many times 478 goes into 19897386.

Advancing to step 1:
478 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 478

On to step 2:
When dividing 19 by 478, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 478

Moving on to step 3:
The number 478 fits into 198 0 times, leaving a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Take the next digit (9) from the dividend and append it to 198, then repeat: 1989 / 478

Going ahead to step 4:
The number 478 fits into 1989 4 times, leaving a remainder of 77.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1912 from 1989, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 478

Going ahead to step 5:
If we divide 777 by 478, we get 1 and a remainder of 299.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 478 from 777 leaves us with 299.
Take the next digit (3) from the dividend and append it to 299, then repeat: 2993 / 478

Moving on to step 6:
2993 divided by 478 is 6 with a remainder of 125.
Write down 6 as next digit of the result. 
Result so far: 416.0
Subtract 2868 from 2993 to get 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 478

Let's proceed to step 7:
The number 478 fits into 1258 2 times, leaving a remainder of 302.
The next digit of our result is 2. 
Result so far: 4162.0
If we take 956 away from 1258, we end up with 302.
Take the next digit (6) from the dividend and append it to 302, then repeat: 3026 / 478

Moving on to step 8:
When dividing 3026 by 478, we get 6 with a remainder of 158.
Use 6 as the next digit of our solution. 
Result so far: 41626.0
The remainder is 158 after subtracting 2868 from 3026.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
478 can be fit into 1580 3 times, resulting in a remainder of 146.
The number 3 becomes the next digit in our result. 
Result so far: 41626.3
Deduct 1434 from 1580 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
1460 divided by 478 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 41626.33
Deduct 1434 from 1460 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 41626.33 and a remainder of 0.026.
