We're dividing 54949651 by 816 
Our goal is to divide 54949651 by 816.

Going ahead to step 1:
The number 816 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 816

Moving on to step 2:
If we divide 54 by 816, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 816

Advancing to step 3:
If we divide 549 by 816, we get 0 and a remainder of 549.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 549 leaves us with 549.
Grab the next digit (4) from the dividend, add it to 549, then carry on: 5494 / 816

Step 4:
If we divide 5494 by 816, we get 6 and a remainder of 598.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4896 from 5494 to get 598.
Take the next digit (9) from the dividend and append it to 598, then repeat: 5989 / 816

Moving on to step 5:
816 can be fit into 5989 7 times, resulting in a remainder of 277.
The next digit of our result is 7. 
Result so far: 67.0
Subtracting 5712 from 5989 leaves us with 277.
Append the next digit (6) from the dividend to 277 and continue with: 2776 / 816

Step 6:
When dividing 2776 by 816, we get 3 with a remainder of 328.
The number 3 becomes the next digit in our result. 
Result so far: 673.0
Subtract 2448 from 2776 to get 328.
Include the next digit (5) from the dividend after 328, then repeat: 3285 / 816

Going ahead to step 7:
816 goes into 3285 4 times with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 6734.0
The remainder is 21 after subtracting 3264 from 3285.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 816

On to step 8:
When dividing 211 by 816, we get 0 with a remainder of 211.
The next digit of our result is 0. 
Result so far: 67340.0
The remainder is 211 after subtracting 0 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 9:
The number 816 fits into 2110 2 times, leaving a remainder of 478.
Write down 2 as next digit of the result. 
Result so far: 67340.2
Subtract 1632 from 2110 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 10:
If we divide 4780 by 816, we get 5 and a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 67340.25
Deduct 4080 from 4780 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
The number 816 fits into 7000 8 times, leaving a remainder of 472.
The next digit of our result is 8. 
Result so far: 67340.258
Deduct 6528 from 7000 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 12:
If we divide 4720 by 816, we get 5 and a remainder of 640.
The next digit of our result is 5. 
Result so far: 67340.2585
Subtracting 4080 from 4720 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 13:
816 goes into 6400 7 times with a remainder of 688.
Put 7 as the next digit of the answer. 
Result so far: 67340.25857
Subtract 5712 from 6400 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 14:
If we divide 6880 by 816, we get 8 and a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 67340.258578
Deduct 6528 from 6880 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
816 can be fit into 3520 4 times, resulting in a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 67340.2585784
The remainder is 256 after subtracting 3264 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 16:
When dividing 2560 by 816, we get 3 with a remainder of 112.
Put 3 as the next digit of the answer. 
Result so far: 67340.25857843
If we take 2448 away from 2560, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 67340.25857843, with a leftover of 1.12e-07.
