43170281 divided by 502 
The aim is to understand the frequency of 502 in 43170281.

On to step 1:
4 divided by 502 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 502

Moving on to step 2:
502 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 502

Moving on to step 3:
If we divide 431 by 502, we get 0 and a remainder of 431.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 431, we end up with 431.
Take the next digit (7) from the dividend and append it to 431, then repeat: 4317 / 502

Let's proceed to step 4:
502 goes into 4317 8 times with a remainder of 301.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 4016 away from 4317, we end up with 301.
Fetch the next digit (0) from the dividend, attach it to 301 and continue: 3010 / 502

Step 5:
If we divide 3010 by 502, we get 5 and a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
If we subtract 2510 from 3010, we get 500.
Grab the next digit (2) from the dividend, add it to 500, then carry on: 5002 / 502

Step 6:
5002 divided by 502 is 9 with a remainder of 484.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
If we subtract 4518 from 5002, we get 484.
Take the next digit (8) from the dividend and append it to 484, then repeat: 4848 / 502

Moving on to step 7:
502 can be fit into 4848 9 times, resulting in a remainder of 330.
Record the quotient 9 as the next digit in the result. 
Result so far: 8599.0
Subtract 4518 from 4848 to get 330.
Include the next digit (1) from the dividend after 330, then repeat: 3301 / 502

Step 8:
502 can be fit into 3301 6 times, resulting in a remainder of 289.
Record the quotient 6 as the next digit in the result. 
Result so far: 85996.0
Subtract 3012 from 3301 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 9:
If we divide 2890 by 502, we get 5 and a remainder of 380.
The next digit of our result is 5. 
Result so far: 85996.5
If we subtract 2510 from 2890, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 10:
The number 502 fits into 3800 7 times, leaving a remainder of 286.
The next digit of our result is 7. 
Result so far: 85996.57
Subtracting 3514 from 3800 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 11:
502 can be fit into 2860 5 times, resulting in a remainder of 350.
Use 5 as the next digit of our solution. 
Result so far: 85996.575
Subtracting 2510 from 2860 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 12:
3500 divided by 502 is 6 with a remainder of 488.
Put 6 as the next digit of the answer. 
Result so far: 85996.5756
Subtracting 3012 from 3500 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 13:
If we divide 4880 by 502, we get 9 and a remainder of 362.
Put 9 as the next digit of the answer. 
Result so far: 85996.57569
The remainder is 362 after subtracting 4518 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 14:
3620 divided by 502 is 7 with a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 85996.575697
Deduct 3514 from 3620 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 15:
When dividing 1060 by 502, we get 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 85996.5756972
The remainder is 56 after subtracting 1004 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 16:
502 goes into 560 1 times with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 85996.57569721
Deduct 502 from 560 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 85996.57569721, and the remainder is 5.8e-08.
