We divide 21293864 by 291
The aim is to understand the frequency of 291 in 21293864.

Let's proceed to step 1:
2 divided by 291 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 291

On to step 2:
291 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 291

Moving on to step 3:
When dividing 212 by 291, we get 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Grab the next digit (9) from the dividend, add it to 212, then carry on: 2129 / 291

Advancing to step 4:
When dividing 2129 by 291, we get 7 with a remainder of 92.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 2037 from 2129 and we're left with 92.
Take the next digit (3) from the dividend and append it to 92, then repeat: 923 / 291

Advancing to step 5:
The number 291 fits into 923 3 times, leaving a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 873 away from 923, we end up with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 291

Let's proceed to step 6:
The number 291 fits into 508 1 times, leaving a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 731.0
The remainder is 217 after subtracting 291 from 508.
Bring next digit (6) of the dividend behind the 217 and repeat the process: 2176 / 291

Let's proceed to step 7:
When dividing 2176 by 291, we get 7 with a remainder of 139.
The number 7 becomes the next digit in our result. 
Result so far: 7317.0
Subtracting 2037 from 2176 leaves us with 139.
Include the next digit (4) from the dividend after 139, then repeat: 1394 / 291

Step 8:
1394 divided by 291 is 4 with a remainder of 230.
Put 4 as the next digit of the answer. 
Result so far: 73174.0
If we subtract 1164 from 1394, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
291 goes into 2300 7 times with a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 73174.7
Subtracting 2037 from 2300 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 10:
The number 291 fits into 2630 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 73174.79
Deduct 2619 from 2630 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
If we divide 110 by 291, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 73174.79
Deduct 0 from 110 and we're left with 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 12:
1100 divided by 291 is 3 with a remainder of 227.
Write down 3 as next digit of the result. 
Result so far: 73174.7903
Subtracting 873 from 1100 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 13:
If we divide 2270 by 291, we get 7 and a remainder of 233.
The next digit of our result is 7. 
Result so far: 73174.79037
The remainder is 233 after subtracting 2037 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 14:
291 goes into 2330 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 73174.790378
If we subtract 2328 from 2330, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
When dividing 20 by 291, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 73174.790378
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 16:
291 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 73174.790378
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 73174.790378 with a remaining 2e-07.
