79138491 divided by 491 
The aim is to understand the frequency of 491 in 79138491.

Step 1:
The number 491 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 491

Advancing to step 2:
491 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 491

Moving on to step 3:
791 divided by 491 is 1 with a remainder of 300.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 491 from 791 and we're left with 300.
Take the next digit (3) from the dividend and append it to 300, then repeat: 3003 / 491

Step 4:
If we divide 3003 by 491, we get 6 and a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 2946 from 3003 to get 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 491

Advancing to step 5:
491 goes into 578 1 times with a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Deduct 491 from 578 and we're left with 87.
Bring next digit (4) of the dividend behind the 87 and repeat the process: 874 / 491

On to step 6:
If we divide 874 by 491, we get 1 and a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 1611.0
If we take 491 away from 874, we end up with 383.
Take the next digit (9) from the dividend and append it to 383, then repeat: 3839 / 491

Let's proceed to step 7:
3839 divided by 491 is 7 with a remainder of 402.
The next digit of our result is 7. 
Result so far: 16117.0
The remainder is 402 after subtracting 3437 from 3839.
Include the next digit (1) from the dividend after 402, then repeat: 4021 / 491

Going ahead to step 8:
If we divide 4021 by 491, we get 8 and a remainder of 93.
Write down 8 as next digit of the result. 
Result so far: 161178.0
The remainder is 93 after subtracting 3928 from 4021.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 9:
491 can be fit into 930 1 times, resulting in a remainder of 439.
The number 1 becomes the next digit in our result. 
Result so far: 161178.1
If we take 491 away from 930, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 10:
491 goes into 4390 8 times with a remainder of 462.
Record the quotient 8 as the next digit in the result. 
Result so far: 161178.18
If we take 3928 away from 4390, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 11:
4620 divided by 491 is 9 with a remainder of 201.
Write down 9 as next digit of the result. 
Result so far: 161178.189
The remainder is 201 after subtracting 4419 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 12:
If we divide 2010 by 491, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 161178.1894
Subtract 1964 from 2010 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
491 goes into 460 0 times with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 161178.1894
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 14:
4600 divided by 491 is 9 with a remainder of 181.
Write down 9 as next digit of the result. 
Result so far: 161178.189409
Subtract 4419 from 4600 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 15:
1810 divided by 491 is 3 with a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 161178.1894093
The remainder is 337 after subtracting 1473 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 16:
The number 491 fits into 3370 6 times, leaving a remainder of 424.
Use 6 as the next digit of our solution. 
Result so far: 161178.18940936
Subtracting 2946 from 3370 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

In conclusion, the division gives 161178.18940936 with a balance of 4.24e-07.
