52807792 ÷ 820 
We're looking to find how many times 820 goes into 52807792.

Step 1:
The number 820 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 820

Going ahead to step 2:
The number 820 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 820

Step 3:
If we divide 528 by 820, we get 0 and a remainder of 528.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 528, we end up with 528.
Grab the next digit (0) from the dividend, add it to 528, then carry on: 5280 / 820

Moving on to step 4:
820 can be fit into 5280 6 times, resulting in a remainder of 360.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 4920 from 5280, we get 360.
Take the next digit (7) from the dividend and append it to 360, then repeat: 3607 / 820

Going ahead to step 5:
The number 820 fits into 3607 4 times, leaving a remainder of 327.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 3280 from 3607 leaves us with 327.
Include the next digit (7) from the dividend after 327, then repeat: 3277 / 820

Advancing to step 6:
If we divide 3277 by 820, we get 3 and a remainder of 817.
The next digit of our result is 3. 
Result so far: 643.0
The remainder is 817 after subtracting 2460 from 3277.
Bring next digit (9) of the dividend behind the 817 and repeat the process: 8179 / 820

Let's proceed to step 7:
8179 divided by 820 is 9 with a remainder of 799.
Use 9 as the next digit of our solution. 
Result so far: 6439.0
If we subtract 7380 from 8179, we get 799.
Include the next digit (2) from the dividend after 799, then repeat: 7992 / 820

Advancing to step 8:
7992 divided by 820 is 9 with a remainder of 612.
Put 9 as the next digit of the answer. 
Result so far: 64399.0
Deduct 7380 from 7992 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 9:
820 goes into 6120 7 times with a remainder of 380.
The next digit of our result is 7. 
Result so far: 64399.7
If we subtract 5740 from 6120, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 10:
820 goes into 3800 4 times with a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 64399.74
Subtracting 3280 from 3800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
The number 820 fits into 5200 6 times, leaving a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 64399.746
The remainder is 280 after subtracting 4920 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 12:
When dividing 2800 by 820, we get 3 with a remainder of 340.
Write down 3 as next digit of the result. 
Result so far: 64399.7463
Subtract 2460 from 2800 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
The number 820 fits into 3400 4 times, leaving a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 64399.74634
Subtract 3280 from 3400 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 14:
820 goes into 1200 1 times with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 64399.746341
The remainder is 380 after subtracting 820 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
If we divide 3800 by 820, we get 4 and a remainder of 520.
The number 4 becomes the next digit in our result. 
Result so far: 64399.7463414
Subtracting 3280 from 3800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 16:
5200 divided by 820 is 6 with a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 64399.74634146
The remainder is 280 after subtracting 4920 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 64399.74634146, with a leftover of 2.8e-07.
