Let's divide 21212495 by 262
The aim is to understand the frequency of 262 in 21212495.

On to step 1:
When dividing 2 by 262, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 262

Let's proceed to step 2:
21 divided by 262 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 262

Step 3:
When dividing 212 by 262, we get 0 with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Grab the next digit (1) from the dividend, add it to 212, then carry on: 2121 / 262

Step 4:
262 goes into 2121 8 times with a remainder of 25.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 2096 from 2121 to get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 262

Advancing to step 5:
When dividing 252 by 262, we get 0 with a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtract 0 from 252 to get 252.
Take the next digit (4) from the dividend and append it to 252, then repeat: 2524 / 262

Let's proceed to step 6:
2524 divided by 262 is 9 with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 809.0
Subtract 2358 from 2524 to get 166.
Grab the next digit (9) from the dividend, add it to 166, then carry on: 1669 / 262

Let's proceed to step 7:
262 goes into 1669 6 times with a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 8096.0
Deduct 1572 from 1669 and we're left with 97.
Include the next digit (5) from the dividend after 97, then repeat: 975 / 262

On to step 8:
262 can be fit into 975 3 times, resulting in a remainder of 189.
Use 3 as the next digit of our solution. 
Result so far: 80963.0
The remainder is 189 after subtracting 786 from 975.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
When dividing 1890 by 262, we get 7 with a remainder of 56.
The next digit of our result is 7. 
Result so far: 80963.7
The remainder is 56 after subtracting 1834 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
The number 262 fits into 560 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 80963.72
Subtract 524 from 560 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
262 goes into 360 1 times with a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 80963.721
Deduct 262 from 360 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
If we divide 980 by 262, we get 3 and a remainder of 194.
The number 3 becomes the next digit in our result. 
Result so far: 80963.7213
Subtracting 786 from 980 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 13:
The number 262 fits into 1940 7 times, leaving a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 80963.72137
If we take 1834 away from 1940, we end up 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 14:
262 can be fit into 1060 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 80963.721374
If we subtract 1048 from 1060, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
When dividing 120 by 262, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 80963.721374
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
The number 262 fits into 1200 4 times, leaving a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 80963.72137404
The remainder is 152 after subtracting 1048 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

In conclusion, the division gives 80963.72137404 with a balance of 1.52e-07.
