We look at the division of 23935401 by 515 
We want to figure out the number of times 23935401 can be divided by 515.

Moving on to step 1:
The number 515 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 515

Step 2:
515 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 515

Moving on to step 3:
515 can be fit into 239 0 times, resulting in a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 239, we get 239.
Grab the next digit (3) from the dividend, add it to 239, then carry on: 2393 / 515

Let's proceed to step 4:
When dividing 2393 by 515, we get 4 with a remainder of 333.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2060 from 2393 to get 333.
Append the next digit (5) from the dividend to 333 and continue with: 3335 / 515

On to step 5:
If we divide 3335 by 515, we get 6 and a remainder of 245.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 3090 from 3335, we get 245.
Fetch the next digit (4) from the dividend, attach it to 245 and continue: 2454 / 515

On to step 6:
When dividing 2454 by 515, we get 4 with a remainder of 394.
Put 4 as the next digit of the answer. 
Result so far: 464.0
If we subtract 2060 from 2454, we get 394.
Append the next digit (0) from the dividend to 394 and continue with: 3940 / 515

Moving on to step 7:
3940 divided by 515 is 7 with a remainder of 335.
The number 7 becomes the next digit in our result. 
Result so far: 4647.0
The remainder is 335 after subtracting 3605 from 3940.
Fetch the next digit (1) from the dividend, attach it to 335 and continue: 3351 / 515

Advancing to step 8:
If we divide 3351 by 515, we get 6 and a remainder of 261.
Put 6 as the next digit of the answer. 
Result so far: 46476.0
The remainder is 261 after subtracting 3090 from 3351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 9:
If we divide 2610 by 515, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 46476.5
Subtract 2575 from 2610 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
350 divided by 515 is 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 46476.5
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 11:
The number 515 fits into 3500 6 times, leaving a remainder of 410.
Put 6 as the next digit of the answer. 
Result so far: 46476.506
If we take 3090 away from 3500, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 12:
515 goes into 4100 7 times with a remainder of 495.
The number 7 becomes the next digit in our result. 
Result so far: 46476.5067
Subtracting 3605 from 4100 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 13:
If we divide 4950 by 515, we get 9 and a remainder of 315.
Write down 9 as next digit of the result. 
Result so far: 46476.50679
Subtract 4635 from 4950 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 14:
3150 divided by 515 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 46476.506796
If we subtract 3090 from 3150, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 15:
515 can be fit into 600 1 times, resulting in a remainder of 85.
Use 1 as the next digit of our solution. 
Result so far: 46476.5067961
The remainder is 85 after subtracting 515 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 16:
The number 515 fits into 850 1 times, leaving a remainder of 335.
Write down 1 as next digit of the result. 
Result so far: 46476.50679611
Deduct 515 from 850 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 46476.50679611, and the remainder is 3.35e-07.
