55845649 ÷ 520 
We're looking to find how many times 520 goes into 55845649.

Let's proceed to step 1:
If we divide 5 by 520, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 520

Moving on to step 2:
520 goes into 55 0 times with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 520

Moving on to step 3:
520 goes into 558 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
If we take 520 away from 558, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 520

Going ahead to step 4:
520 can be fit into 384 0 times, resulting in a remainder of 384.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 384 after subtracting 0 from 384.
Bring next digit (5) of the dividend behind the 384 and repeat the process: 3845 / 520

Moving on to step 5:
3845 divided by 520 is 7 with a remainder of 205.
Write down 7 as next digit of the result. 
Result so far: 107.0
Deduct 3640 from 3845 and we're left with 205.
Take the next digit (6) from the dividend and append it to 205, then repeat: 2056 / 520

Advancing to step 6:
2056 divided by 520 is 3 with a remainder of 496.
Put 3 as the next digit of the answer. 
Result so far: 1073.0
Subtracting 1560 from 2056 leaves us with 496.
Append the next digit (4) from the dividend to 496 and continue with: 4964 / 520

Moving on to step 7:
If we divide 4964 by 520, we get 9 and a remainder of 284.
Record the quotient 9 as the next digit in the result. 
Result so far: 10739.0
If we subtract 4680 from 4964, we get 284.
Bring next digit (9) of the dividend behind the 284 and repeat the process: 2849 / 520

Moving on to step 8:
2849 divided by 520 is 5 with a remainder of 249.
Use 5 as the next digit of our solution. 
Result so far: 107395.0
If we subtract 2600 from 2849, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 9:
520 can be fit into 2490 4 times, resulting in a remainder of 410.
Record the quotient 4 as the next digit in the result. 
Result so far: 107395.4
The remainder is 410 after subtracting 2080 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
520 can be fit into 4100 7 times, resulting in a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 107395.47
The remainder is 460 after subtracting 3640 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
When dividing 4600 by 520, we get 8 with a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 107395.478
Deduct 4160 from 4600 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
The number 520 fits into 4400 8 times, leaving a remainder of 240.
The next digit of our result is 8. 
Result so far: 107395.4788
Subtracting 4160 from 4400 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 107395.4788 with a remaining 0.0024.
