52001056 ÷ 646 
We're looking to find how many times 646 goes into 52001056.

Advancing to step 1:
646 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 646

Moving on to step 2:
The number 646 fits into 52 0 times, leaving a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 646

Going ahead to step 3:
520 divided by 646 is 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 520, we end up with 520.
Include the next digit (0) from the dividend after 520, then repeat: 5200 / 646

Let's proceed to step 4:
If we divide 5200 by 646, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 5168 from 5200 and we're left with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 646

Step 5:
When dividing 321 by 646, we get 0 with a remainder of 321.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 321, we end up with 321.
Take the next digit (0) from the dividend and append it to 321, then repeat: 3210 / 646

Moving on to step 6:
646 goes into 3210 4 times with a remainder of 626.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
If we take 2584 away from 3210, we end up with 626.
Bring next digit (5) of the dividend behind the 626 and repeat the process: 6265 / 646

Let's proceed to step 7:
When dividing 6265 by 646, we get 9 with a remainder of 451.
Use 9 as the next digit of our solution. 
Result so far: 8049.0
If we subtract 5814 from 6265, we get 451.
Grab the next digit (6) from the dividend, add it to 451, then carry on: 4516 / 646

Let's proceed to step 8:
When dividing 4516 by 646, we get 6 with a remainder of 640.
Record the quotient 6 as the next digit in the result. 
Result so far: 80496.0
Deduct 3876 from 4516 and we're left 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.

Let's proceed to step 9:
646 can be fit into 6400 9 times, resulting in a remainder of 586.
Use 9 as the next digit of our solution. 
Result so far: 80496.9
Subtract 5814 from 6400 to get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 10:
The number 646 fits into 5860 9 times, leaving a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 80496.99
If we subtract 5814 from 5860, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 80496.99, and the remainder is 0.046.
