Let's divide 74729456 by 491
The aim is to understand the frequency of 491 in 74729456.

Advancing to step 1:
When dividing 7 by 491, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 491

Going ahead to step 2:
The number 491 fits into 74 0 times, leaving a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Append the next digit (7) from the dividend to 74 and continue with: 747 / 491

Moving on to step 3:
491 can be fit into 747 1 times, resulting in a remainder of 256.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 491 away from 747, we end up with 256.
Include the next digit (2) from the dividend after 256, then repeat: 2562 / 491

On to step 4:
The number 491 fits into 2562 5 times, leaving a remainder of 107.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2455 from 2562 leaves us with 107.
Fetch the next digit (9) from the dividend, attach it to 107 and continue: 1079 / 491

Moving on to step 5:
The number 491 fits into 1079 2 times, leaving a remainder of 97.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we subtract 982 from 1079, we get 97.
Grab the next digit (4) from the dividend, add it to 97, then carry on: 974 / 491

Advancing to step 6:
When dividing 974 by 491, we get 1 with a remainder of 483.
Put 1 as the next digit of the answer. 
Result so far: 1521.0
If we subtract 491 from 974, we get 483.
Append the next digit (5) from the dividend to 483 and continue with: 4835 / 491

Advancing to step 7:
When dividing 4835 by 491, we get 9 with a remainder of 416.
Put 9 as the next digit of the answer. 
Result so far: 15219.0
If we take 4419 away from 4835, we end up with 416.
Bring next digit (6) of the dividend behind the 416 and repeat the process: 4166 / 491

Step 8:
491 goes into 4166 8 times with a remainder of 238.
The number 8 becomes the next digit in our result. 
Result so far: 152198.0
The remainder is 238 after subtracting 3928 from 4166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 9:
491 goes into 2380 4 times with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 152198.4
Subtracting 1964 from 2380 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 10:
491 can be fit into 4160 8 times, resulting in a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 152198.48
If we take 3928 away from 4160, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
The number 491 fits into 2320 4 times, leaving a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 152198.484
If we subtract 1964 from 2320, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 12:
3560 divided by 491 is 7 with a remainder of 123.
Put 7 as the next digit of the answer. 
Result so far: 152198.4847
If we take 3437 away from 3560, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 13:
491 can be fit into 1230 2 times, resulting in a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 152198.48472
Deduct 982 from 1230 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 14:
If we divide 2480 by 491, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 152198.484725
The remainder is 25 after subtracting 2455 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 15:
250 divided by 491 is 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 152198.484725
If we take 0 away from 250, we end up 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.

Going ahead to step 16:
491 goes into 2500 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 152198.48472505
If we take 2455 away from 2500, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 152198.48472505 and a remainder of 4.5e-08.
