We're dividing 19915688 by 498 
Let's see how many times 498 fits into 19915688.

Advancing to step 1:
1 divided by 498 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 498

Going ahead to step 2:
19 divided by 498 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 498

Let's proceed to step 3:
498 goes into 199 0 times with a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 199, we end up with 199.
Include the next digit (1) from the dividend after 199, then repeat: 1991 / 498

Let's proceed to step 4:
498 can be fit into 1991 3 times, resulting in a remainder of 497.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1494 from 1991 leaves us with 497.
Append the next digit (5) from the dividend to 497 and continue with: 4975 / 498

On to step 5:
If we divide 4975 by 498, we get 9 and a remainder of 493.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 4482 from 4975, we get 493.
Take the next digit (6) from the dividend and append it to 493, then repeat: 4936 / 498

Step 6:
The number 498 fits into 4936 9 times, leaving a remainder of 454.
Put 9 as the next digit of the answer. 
Result so far: 399.0
The remainder is 454 after subtracting 4482 from 4936.
Include the next digit (8) from the dividend after 454, then repeat: 4548 / 498

Going ahead to step 7:
If we divide 4548 by 498, we get 9 and a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 3999.0
Subtracting 4482 from 4548 leaves us with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 498

Going ahead to step 8:
668 divided by 498 is 1 with a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 39991.0
If we take 498 away from 668, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
When dividing 1700 by 498, we get 3 with a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 39991.3
Subtract 1494 from 1700 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 10:
498 can be fit into 2060 4 times, resulting in a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 39991.34
If we subtract 1992 from 2060, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
If we divide 680 by 498, we get 1 and a remainder of 182.
The next digit of our result is 1. 
Result so far: 39991.341
Subtract 498 from 680 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 12:
The number 498 fits into 1820 3 times, leaving a remainder of 326.
Record the quotient 3 as the next digit in the result. 
Result so far: 39991.3413
Subtract 1494 from 1820 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 13:
3260 divided by 498 is 6 with a remainder of 272.
The next digit of our result is 6. 
Result so far: 39991.34136
Subtract 2988 from 3260 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 14:
2720 divided by 498 is 5 with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 39991.341365
If we take 2490 away from 2720, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 15:
If we divide 2300 by 498, we get 4 and a remainder of 308.
Write down 4 as next digit of the result. 
Result so far: 39991.3413654
Subtracting 1992 from 2300 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 16:
The number 498 fits into 3080 6 times, leaving a remainder of 92.
The next digit of our result is 6. 
Result so far: 39991.34136546
If we subtract 2988 from 3080, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 39991.34136546, with a leftover of 9.2e-08.
