21461205 ÷ 502 
The aim is to understand the frequency of 502 in 21461205.

On to step 1:
When dividing 2 by 502, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 502

Moving on to step 2:
502 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 502

Let's proceed to step 3:
502 can be fit into 214 0 times, resulting in a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Bring next digit (6) of the dividend behind the 214 and repeat the process: 2146 / 502

Moving on to step 4:
The number 502 fits into 2146 4 times, leaving a remainder of 138.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2008 from 2146, we get 138.
Fetch the next digit (1) from the dividend, attach it to 138 and continue: 1381 / 502

Let's proceed to step 5:
502 can be fit into 1381 2 times, resulting in a remainder of 377.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 1004 from 1381 leaves us with 377.
Grab the next digit (2) from the dividend, add it to 377, then carry on: 3772 / 502

On to step 6:
502 can be fit into 3772 7 times, resulting in a remainder of 258.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
Subtract 3514 from 3772 to get 258.
Append the next digit (0) from the dividend to 258 and continue with: 2580 / 502

Step 7:
When dividing 2580 by 502, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 4275.0
Deduct 2510 from 2580 and we're left with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 502

Step 8:
If we divide 705 by 502, we get 1 and a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 42751.0
Subtracting 502 from 705 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 9:
If we divide 2030 by 502, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 42751.4
The remainder is 22 after subtracting 2008 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
If we divide 220 by 502, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 42751.4
If we take 0 away from 220, we end up 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.

Let's proceed to step 11:
The number 502 fits into 2200 4 times, leaving a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 42751.404
Subtracting 2008 from 2200 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
502 goes into 1920 3 times with a remainder of 414.
The next digit of our result is 3. 
Result so far: 42751.4043
Subtract 1506 from 1920 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 13:
The number 502 fits into 4140 8 times, leaving a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 42751.40438
If we take 4016 away from 4140, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 14:
When dividing 1240 by 502, we get 2 with a remainder of 236.
Put 2 as the next digit of the answer. 
Result so far: 42751.404382
If we subtract 1004 from 1240, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 15:
502 goes into 2360 4 times with a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 42751.4043824
Subtracting 2008 from 2360 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 16:
502 can be fit into 3520 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 42751.40438247
The remainder is 6 after subtracting 3514 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 42751.40438247, with a leftover of 6e-09.
