21991831 divided by 262 
The aim is to understand the frequency of 262 in 21991831.

Advancing to step 1:
262 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 262

On to step 2:
262 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 262

Let's proceed to step 3:
If we divide 219 by 262, we get 0 and a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 219 leaves us with 219.
Grab the next digit (9) from the dividend, add it to 219, then carry on: 2199 / 262

Let's proceed to step 4:
2199 divided by 262 is 8 with a remainder of 103.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 2096 away from 2199, we end up with 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 262

Step 5:
When dividing 1031 by 262, we get 3 with a remainder of 245.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 786 from 1031 leaves us with 245.
Bring next digit (8) of the dividend behind the 245 and repeat the process: 2458 / 262

Moving on to step 6:
When dividing 2458 by 262, we get 9 with a remainder of 100.
The next digit of our result is 9. 
Result so far: 839.0
Subtracting 2358 from 2458 leaves us with 100.
Include the next digit (3) from the dividend after 100, then repeat: 1003 / 262

Moving on to step 7:
1003 divided by 262 is 3 with a remainder of 217.
The next digit of our result is 3. 
Result so far: 8393.0
Subtract 786 from 1003 to get 217.
Bring next digit (1) of the dividend behind the 217 and repeat the process: 2171 / 262

Step 8:
When dividing 2171 by 262, we get 8 with a remainder of 75.
Write down 8 as next digit of the result. 
Result so far: 83938.0
Subtracting 2096 from 2171 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
When dividing 750 by 262, we get 2 with a remainder of 226.
Write down 2 as next digit of the result. 
Result so far: 83938.2
If we take 524 away from 750, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 10:
If we divide 2260 by 262, we get 8 and a remainder of 164.
The next digit of our result is 8. 
Result so far: 83938.28
Subtract 2096 from 2260 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 11:
The number 262 fits into 1640 6 times, leaving a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 83938.286
Subtract 1572 from 1640 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
When dividing 680 by 262, we get 2 with a remainder of 156.
Put 2 as the next digit of the answer. 
Result so far: 83938.2862
The remainder is 156 after subtracting 524 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 13:
1560 divided by 262 is 5 with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 83938.28625
Deduct 1310 from 1560 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 14:
If we divide 2500 by 262, we get 9 and a remainder of 142.
The next digit of our result is 9. 
Result so far: 83938.286259
The remainder is 142 after subtracting 2358 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 15:
262 can be fit into 1420 5 times, resulting in a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 83938.2862595
Subtract 1310 from 1420 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 16:
262 can be fit into 1100 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 83938.28625954
The remainder is 52 after subtracting 1048 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 83938.28625954, with a leftover of 5.2e-08.
