52016519 ÷ 665 
We want to divide 52016519 by 665.

On to step 1:
If we divide 5 by 665, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 665

Step 2:
665 can be fit into 52 0 times, resulting in a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 665

Let's proceed to step 3:
665 goes into 520 0 times with a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 520 and we're left with 520.
Fetch the next digit (1) from the dividend, attach it to 520 and continue: 5201 / 665

Step 4:
When dividing 5201 by 665, we get 7 with a remainder of 546.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4655 from 5201, we get 546.
Grab the next digit (6) from the dividend, add it to 546, then carry on: 5466 / 665

On to step 5:
665 goes into 5466 8 times with a remainder of 146.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 146 after subtracting 5320 from 5466.
Bring next digit (5) of the dividend behind the 146 and repeat the process: 1465 / 665

Going ahead to step 6:
If we divide 1465 by 665, we get 2 and a remainder of 135.
The next digit of our result is 2. 
Result so far: 782.0
Subtract 1330 from 1465 to get 135.
Append the next digit (1) from the dividend to 135 and continue with: 1351 / 665

Advancing to step 7:
The number 665 fits into 1351 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 7822.0
Subtract 1330 from 1351 to get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 665

Moving on to step 8:
The number 665 fits into 219 0 times, leaving a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 78220.0
If we take 0 away from 219, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 9:
665 goes into 2190 3 times with a remainder of 195.
Use 3 as the next digit of our solution. 
Result so far: 78220.3
The remainder is 195 after subtracting 1995 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
If we divide 1950 by 665, we get 2 and a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 78220.32
If we subtract 1330 from 1950, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 11:
665 can be fit into 6200 9 times, resulting in a remainder of 215.
The number 9 becomes the next digit in our result. 
Result so far: 78220.329
The remainder is 215 after subtracting 5985 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 12:
If we divide 2150 by 665, we get 3 and a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 78220.3293
Deduct 1995 from 2150 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 13:
665 can be fit into 1550 2 times, resulting in a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 78220.32932
Subtracting 1330 from 1550 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
When dividing 2200 by 665, we get 3 with a remainder of 205.
The number 3 becomes the next digit in our result. 
Result so far: 78220.329323
If we take 1995 away from 2200, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 15:
When dividing 2050 by 665, we get 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 78220.3293233
If we subtract 1995 from 2050, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 78220.3293233 with a remaining 5.5e-07.
