19850016 ÷ 813 
Our goal is to divide 19850016 by 813.

Going ahead to step 1:
813 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 813

Step 2:
The number 813 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 813

On to step 3:
When dividing 198 by 813, we get 0 with a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Bring next digit (5) of the dividend behind the 198 and repeat the process: 1985 / 813

Step 4:
813 goes into 1985 2 times with a remainder of 359.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1626 from 1985 to get 359.
Append the next digit (0) from the dividend to 359 and continue with: 3590 / 813

Step 5:
The number 813 fits into 3590 4 times, leaving a remainder of 338.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 3252 from 3590 leaves us with 338.
Fetch the next digit (0) from the dividend, attach it to 338 and continue: 3380 / 813

Going ahead to step 6:
813 goes into 3380 4 times with a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 244.0
If we take 3252 away from 3380, we end up with 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 813

Step 7:
813 can be fit into 1281 1 times, resulting in a remainder of 468.
Write down 1 as next digit of the result. 
Result so far: 2441.0
Subtract 813 from 1281 to get 468.
Fetch the next digit (6) from the dividend, attach it to 468 and continue: 4686 / 813

Step 8:
4686 divided by 813 is 5 with a remainder of 621.
The next digit of our result is 5. 
Result so far: 24415.0
Deduct 4065 from 4686 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Going ahead to step 9:
When dividing 6210 by 813, we get 7 with a remainder of 519.
Use 7 as the next digit of our solution. 
Result so far: 24415.7
If we take 5691 away from 6210, we end up with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 10:
The number 813 fits into 5190 6 times, leaving a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 24415.76
The remainder is 312 after subtracting 4878 from 5190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
813 goes into 3120 3 times with a remainder of 681.
The number 3 becomes the next digit in our result. 
Result so far: 24415.763
Subtract 2439 from 3120 to get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Advancing to step 12:
6810 divided by 813 is 8 with a remainder of 306.
The next digit of our result is 8. 
Result so far: 24415.7638
Deduct 6504 from 6810 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 13:
The number 813 fits into 3060 3 times, leaving a remainder of 621.
Put 3 as the next digit of the answer. 
Result so far: 24415.76383
Deduct 2439 from 3060 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Step 14:
If we divide 6210 by 813, we get 7 and a remainder of 519.
Put 7 as the next digit of the answer. 
Result so far: 24415.763837
Subtract 5691 from 6210 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 15:
813 can be fit into 5190 6 times, resulting in a remainder of 312.
The next digit of our result is 6. 
Result so far: 24415.7638376
Subtracting 4878 from 5190 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 16:
3120 divided by 813 is 3 with a remainder of 681.
Put 3 as the next digit of the answer. 
Result so far: 24415.76383763
Subtract 2439 from 3120 to get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The final outcome is 24415.76383763, with a leftover of 6.81e-07.
