75951030 ÷ 491 
The aim is to understand the frequency of 491 in 75951030.

On to step 1:
7 divided by 491 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 491

On to step 2:
The number 491 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 491

Going ahead to step 3:
If we divide 759 by 491, we get 1 and a remainder of 268.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 491 from 759 leaves us with 268.
Include the next digit (5) from the dividend after 268, then repeat: 2685 / 491

Going ahead to step 4:
2685 divided by 491 is 5 with a remainder of 230.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2455 away from 2685, we end up with 230.
Include the next digit (1) from the dividend after 230, then repeat: 2301 / 491

Step 5:
When dividing 2301 by 491, we get 4 with a remainder of 337.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Subtract 1964 from 2301 to get 337.
Fetch the next digit (0) from the dividend, attach it to 337 and continue: 3370 / 491

Moving on to step 6:
491 goes into 3370 6 times with a remainder of 424.
Write down 6 as next digit of the result. 
Result so far: 1546.0
The remainder is 424 after subtracting 2946 from 3370.
Append the next digit (3) from the dividend to 424 and continue with: 4243 / 491

Moving on to step 7:
4243 divided by 491 is 8 with a remainder of 315.
The number 8 becomes the next digit in our result. 
Result so far: 15468.0
The remainder is 315 after subtracting 3928 from 4243.
Include the next digit (0) from the dividend after 315, then repeat: 3150 / 491

On to step 8:
If we divide 3150 by 491, we get 6 and a remainder of 204.
Record the quotient 6 as the next digit in the result. 
Result so far: 154686.0
Subtracting 2946 from 3150 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 9:
The number 491 fits into 2040 4 times, leaving a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 154686.4
Subtracting 1964 from 2040 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
760 divided by 491 is 1 with a remainder of 269.
Put 1 as the next digit of the answer. 
Result so far: 154686.41
If we subtract 491 from 760, we get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 11:
491 goes into 2690 5 times with a remainder of 235.
The next digit of our result is 5. 
Result so far: 154686.415
Subtract 2455 from 2690 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 12:
If we divide 2350 by 491, we get 4 and a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 154686.4154
If we take 1964 away from 2350, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 13:
If we divide 3860 by 491, we get 7 and a remainder of 423.
The number 7 becomes the next digit in our result. 
Result so far: 154686.41547
If we take 3437 away from 3860, we end up with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 14:
491 goes into 4230 8 times with a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 154686.415478
The remainder is 302 after subtracting 3928 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 15:
When dividing 3020 by 491, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 154686.4154786
Subtract 2946 from 3020 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 16:
740 divided by 491 is 1 with a remainder of 249.
Record the quotient 1 as the next digit in the result. 
Result so far: 154686.41547861
Subtracting 491 from 740 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

The final result is 154686.41547861 with a remainder of 2.49e-07.
