54515684 divided by 829 
We're looking to find how many times 829 goes into 54515684.

Going ahead to step 1:
829 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
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 / 829

On to step 2:
829 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 829

Step 3:
When dividing 545 by 829, we get 0 with a remainder of 545.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 545, we end up with 545.
Bring next digit (1) of the dividend behind the 545 and repeat the process: 5451 / 829

Let's proceed to step 4:
829 can be fit into 5451 6 times, resulting in a remainder of 477.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4974 from 5451 to get 477.
Grab the next digit (5) from the dividend, add it to 477, then carry on: 4775 / 829

Going ahead to step 5:
The number 829 fits into 4775 5 times, leaving a remainder of 630.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 4145 away from 4775, we end up with 630.
Include the next digit (6) from the dividend after 630, then repeat: 6306 / 829

Going ahead to step 6:
829 can be fit into 6306 7 times, resulting in a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 657.0
If we take 5803 away from 6306, we end up with 503.
Append the next digit (8) from the dividend to 503 and continue with: 5038 / 829

Advancing to step 7:
If we divide 5038 by 829, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 6576.0
If we take 4974 away from 5038, we end up with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 829

Let's proceed to step 8:
829 goes into 644 0 times with a remainder of 644.
Record the quotient 0 as the next digit in the result. 
Result so far: 65760.0
If we subtract 0 from 644, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 9:
6440 divided by 829 is 7 with a remainder of 637.
The number 7 becomes the next digit in our result. 
Result so far: 65760.7
If we subtract 5803 from 6440, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Step 10:
829 can be fit into 6370 7 times, resulting in a remainder of 567.
Write down 7 as next digit of the result. 
Result so far: 65760.77
The remainder is 567 after subtracting 5803 from 6370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

The final outcome is 65760.77, with a leftover of 0.567.
