We're dividing 52977520 by 646 
Let's see how many times 646 fits into 52977520.

Let's proceed to step 1:
When dividing 5 by 646, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 646

On to step 2:
The number 646 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 646

Advancing to step 3:
646 can be fit into 529 0 times, resulting in a remainder of 529.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 529, we get 529.
Append the next digit (7) from the dividend to 529 and continue with: 5297 / 646

On to step 4:
646 goes into 5297 8 times with a remainder of 129.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 5168 away from 5297, we end up with 129.
Grab the next digit (7) from the dividend, add it to 129, then carry on: 1297 / 646

Let's proceed to step 5:
646 can be fit into 1297 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 1292 from 1297 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 646

Advancing to step 6:
646 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 646

Step 7:
552 divided by 646 is 0 with a remainder of 552.
Write down 0 as next digit of the result. 
Result so far: 8200.0
Subtract 0 from 552 to get 552.
Grab the next digit (0) from the dividend, add it to 552, then carry on: 5520 / 646

Moving on to step 8:
646 can be fit into 5520 8 times, resulting in a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 82008.0
If we take 5168 away from 5520, we end up 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.

Step 9:
646 goes into 3520 5 times with a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 82008.5
Deduct 3230 from 3520 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
When dividing 2900 by 646, we get 4 with a remainder of 316.
The next digit of our result is 4. 
Result so far: 82008.54
If we take 2584 away from 2900, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 11:
If we divide 3160 by 646, we get 4 and a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 82008.544
Subtract 2584 from 3160 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

In conclusion, the division gives 82008.544 with a balance of 0.0576.
