We look at the division of 23432861 by 791 
The aim is to understand the frequency of 791 in 23432861.

Advancing to step 1:
791 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 791

Step 2:
When dividing 23 by 791, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 791

Going ahead to step 3:
791 goes into 234 0 times with a remainder of 234.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 234 and we're left with 234.
Include the next digit (3) from the dividend after 234, then repeat: 2343 / 791

Going ahead to step 4:
791 goes into 2343 2 times with a remainder of 761.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 761 after subtracting 1582 from 2343.
Grab the next digit (2) from the dividend, add it to 761, then carry on: 7612 / 791

Step 5:
When dividing 7612 by 791, we get 9 with a remainder of 493.
The next digit of our result is 9. 
Result so far: 29.0
Deduct 7119 from 7612 and we're left with 493.
Include the next digit (8) from the dividend after 493, then repeat: 4938 / 791

Let's proceed to step 6:
When dividing 4938 by 791, we get 6 with a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 296.0
Subtracting 4746 from 4938 leaves us with 192.
Include the next digit (6) from the dividend after 192, then repeat: 1926 / 791

Going ahead to step 7:
791 can be fit into 1926 2 times, resulting in a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 2962.0
The remainder is 344 after subtracting 1582 from 1926.
Take the next digit (1) from the dividend and append it to 344, then repeat: 3441 / 791

Going ahead to step 8:
When dividing 3441 by 791, we get 4 with a remainder of 277.
The next digit of our result is 4. 
Result so far: 29624.0
Deduct 3164 from 3441 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 9:
2770 divided by 791 is 3 with a remainder of 397.
Use 3 as the next digit of our solution. 
Result so far: 29624.3
If we take 2373 away from 2770, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Let's proceed to step 10:
The number 791 fits into 3970 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 29624.35
Subtracting 3955 from 3970 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
791 goes into 150 0 times with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 29624.35
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
If we divide 1500 by 791, we get 1 and a remainder of 709.
Record the quotient 1 as the next digit in the result. 
Result so far: 29624.3501
If we take 791 away from 1500, we end up with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Let's proceed to step 13:
The number 791 fits into 7090 8 times, leaving a remainder of 762.
Put 8 as the next digit of the answer. 
Result so far: 29624.35018
If we subtract 6328 from 7090, we get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Step 14:
791 can be fit into 7620 9 times, resulting in a remainder of 501.
The number 9 becomes the next digit in our result. 
Result so far: 29624.350189
Subtract 7119 from 7620 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Going ahead to step 15:
791 goes into 5010 6 times with a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 29624.3501896
Deduct 4746 from 5010 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 16:
2640 divided by 791 is 3 with a remainder of 267.
Use 3 as the next digit of our solution. 
Result so far: 29624.35018963
If we subtract 2373 from 2640, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

After the division, we end up with 29624.35018963 and a remainder of 2.67e-07.
