Let's divide 19996389 by 463
Let's see how many times 463 fits into 19996389.

Advancing to step 1:
463 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 463

Advancing to step 2:
19 divided by 463 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 463

Moving on to step 3:
199 divided by 463 is 0 with a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 199 to get 199.
Take the next digit (9) from the dividend and append it to 199, then repeat: 1999 / 463

Let's proceed to step 4:
The number 463 fits into 1999 4 times, leaving a remainder of 147.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1852 from 1999, we get 147.
Bring next digit (6) of the dividend behind the 147 and repeat the process: 1476 / 463

Moving on to step 5:
If we divide 1476 by 463, we get 3 and a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 1389 from 1476 and we're left with 87.
Bring next digit (3) of the dividend behind the 87 and repeat the process: 873 / 463

Let's proceed to step 6:
463 goes into 873 1 times with a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 431.0
If we take 463 away from 873, we end up with 410.
Append the next digit (8) from the dividend to 410 and continue with: 4108 / 463

Going ahead to step 7:
When dividing 4108 by 463, we get 8 with a remainder of 404.
Use 8 as the next digit of our solution. 
Result so far: 4318.0
If we subtract 3704 from 4108, we get 404.
Include the next digit (9) from the dividend after 404, then repeat: 4049 / 463

Going ahead to step 8:
If we divide 4049 by 463, we get 8 and a remainder of 345.
Use 8 as the next digit of our solution. 
Result so far: 43188.0
If we take 3704 away from 4049, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 9:
463 goes into 3450 7 times with a remainder of 209.
Put 7 as the next digit of the answer. 
Result so far: 43188.7
The remainder is 209 after subtracting 3241 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 10:
463 goes into 2090 4 times with a remainder of 238.
The next digit of our result is 4. 
Result so far: 43188.74
Subtracting 1852 from 2090 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 11:
If we divide 2380 by 463, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 43188.745
Deduct 2315 from 2380 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
If we divide 650 by 463, we get 1 and a remainder of 187.
The number 1 becomes the next digit in our result. 
Result so far: 43188.7451
Deduct 463 from 650 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 13:
463 can be fit into 1870 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 43188.74514
Subtracting 1852 from 1870 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
If we divide 180 by 463, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 43188.74514
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
The number 463 fits into 1800 3 times, leaving a remainder of 411.
The next digit of our result is 3. 
Result so far: 43188.7451403
Subtracting 1389 from 1800 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Going ahead to step 16:
If we divide 4110 by 463, we get 8 and a remainder of 406.
Use 8 as the next digit of our solution. 
Result so far: 43188.74514038
If we take 3704 away from 4110, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

After the division, we end up with 43188.74514038 and a remainder of 4.06e-07.
