806599 ÷ 520 
We're looking to find how many times 520 goes into 806599.

Advancing to step 1:
8 divided by 520 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 520

On to step 2:
When dividing 80 by 520, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 520

Advancing to step 3:
520 can be fit into 806 1 times, resulting in a remainder of 286.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 520 from 806 leaves us with 286.
Bring next digit (5) of the dividend behind the 286 and repeat the process: 2865 / 520

Going ahead to step 4:
520 can be fit into 2865 5 times, resulting in a remainder of 265.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2600 away from 2865, we end up with 265.
Grab the next digit (9) from the dividend, add it to 265, then carry on: 2659 / 520

Advancing to step 5:
When dividing 2659 by 520, we get 5 with a remainder of 59.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtracting 2600 from 2659 leaves us with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 520

Moving on to step 6:
If we divide 599 by 520, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1551.0
Deduct 520 from 599 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
790 divided by 520 is 1 with a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 1551.1
The remainder is 270 after subtracting 520 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 8:
520 can be fit into 2700 5 times, resulting in a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 1551.15
Deduct 2600 from 2700 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 9:
If we divide 1000 by 520, we get 1 and a remainder of 480.
The number 1 becomes the next digit in our result. 
Result so far: 1551.151
The remainder is 480 after subtracting 520 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 10:
When dividing 4800 by 520, we get 9 with a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 1551.1519
If we take 4680 away from 4800, we end up with 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 11:
The number 520 fits into 1200 2 times, leaving a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 1551.15192
If we take 1040 away from 1200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 12:
The number 520 fits into 1600 3 times, leaving a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 1551.151923
If we take 1560 away from 1600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
520 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 1551.151923
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
520 can be fit into 4000 7 times, resulting in a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 1551.15192307
If we subtract 3640 from 4000, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 1551.15192307 and a remainder of 3.6e-07.
