Let's divide 3161305 by 520
Our goal is to divide 3161305 by 520.

Step 1:
520 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 520

Let's proceed to step 2:
If we divide 31 by 520, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 520

Let's proceed to step 3:
316 divided by 520 is 0 with a remainder of 316.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 316 after subtracting 0 from 316.
Append the next digit (1) from the dividend to 316 and continue with: 3161 / 520

Let's proceed to step 4:
520 can be fit into 3161 6 times, resulting in a remainder of 41.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 3120 from 3161 leaves us with 41.
Take the next digit (3) from the dividend and append it to 41, then repeat: 413 / 520

Step 5:
When dividing 413 by 520, we get 0 with a remainder of 413.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we subtract 0 from 413, we get 413.
Take the next digit (0) from the dividend and append it to 413, then repeat: 4130 / 520

Moving on to step 6:
520 goes into 4130 7 times with a remainder of 490.
Put 7 as the next digit of the answer. 
Result so far: 607.0
The remainder is 490 after subtracting 3640 from 4130.
Bring next digit (5) of the dividend behind the 490 and repeat the process: 4905 / 520

Step 7:
520 goes into 4905 9 times with a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 6079.0
Deduct 4680 from 4905 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 8:
2250 divided by 520 is 4 with a remainder of 170.
The next digit of our result is 4. 
Result so far: 6079.4
Subtract 2080 from 2250 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
The number 520 fits into 1700 3 times, leaving a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 6079.43
Deduct 1560 from 1700 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
520 can be fit into 1400 2 times, resulting in a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 6079.432
Deduct 1040 from 1400 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 11:
520 can be fit into 3600 6 times, resulting in a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 6079.4326
The remainder is 480 after subtracting 3120 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 12:
When dividing 4800 by 520, we get 9 with a remainder of 120.
Write down 9 as next digit of the result. 
Result so far: 6079.43269
The remainder is 120 after subtracting 4680 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
520 goes into 1200 2 times with a remainder of 160.
The next digit of our result is 2. 
Result so far: 6079.432692
Subtract 1040 from 1200 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
If we divide 1600 by 520, we get 3 and a remainder of 40.
The next digit of our result is 3. 
Result so far: 6079.4326923
Subtracting 1560 from 1600 leaves us 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.

Moving on to step 15:
If we divide 400 by 520, we get 0 and a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 6079.4326923
If we take 0 away from 400, we end up 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.

The final outcome is 6079.4326923, with a leftover of 4e-07.
