53465720 ÷ 515 
Let's see how many times 515 fits into 53465720.

Advancing to step 1:
If we divide 5 by 515, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 515

Moving on to step 2:
When dividing 53 by 515, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 515

Advancing to step 3:
The number 515 fits into 534 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 515 from 534 and we're left with 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 515

Going ahead to step 4:
515 goes into 196 0 times with a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 196 after subtracting 0 from 196.
Take the next digit (5) from the dividend and append it to 196, then repeat: 1965 / 515

Let's proceed to step 5:
515 can be fit into 1965 3 times, resulting in a remainder of 420.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 1545 from 1965, we get 420.
Include the next digit (7) from the dividend after 420, then repeat: 4207 / 515

On to step 6:
The number 515 fits into 4207 8 times, leaving a remainder of 87.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
Subtracting 4120 from 4207 leaves us with 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 515

Moving on to step 7:
The number 515 fits into 872 1 times, leaving a remainder of 357.
Put 1 as the next digit of the answer. 
Result so far: 10381.0
If we subtract 515 from 872, we get 357.
Include the next digit (0) from the dividend after 357, then repeat: 3570 / 515

Going ahead to step 8:
3570 divided by 515 is 6 with a remainder of 480.
The next digit of our result is 6. 
Result so far: 103816.0
Subtracting 3090 from 3570 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 9:
515 can be fit into 4800 9 times, resulting in a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 103816.9
The remainder is 165 after subtracting 4635 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
515 can be fit into 1650 3 times, resulting in a remainder of 105.
Record the quotient 3 as the next digit in the result. 
Result so far: 103816.93
Subtracting 1545 from 1650 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 11:
If we divide 1050 by 515, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 103816.932
If we take 1030 away from 1050, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
515 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 103816.932
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
If we divide 2000 by 515, we get 3 and a remainder of 455.
The number 3 becomes the next digit in our result. 
Result so far: 103816.93203
If we subtract 1545 from 2000, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 14:
If we divide 4550 by 515, we get 8 and a remainder of 430.
Put 8 as the next digit of the answer. 
Result so far: 103816.932038
Subtract 4120 from 4550 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 15:
4300 divided by 515 is 8 with a remainder of 180.
The next digit of our result is 8. 
Result so far: 103816.9320388
Subtracting 4120 from 4300 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 103816.9320388 and a remainder of 1.8e-06.
