Let's divide 39458172 by 491
The aim is to understand the frequency of 491 in 39458172.

Moving on to step 1:
491 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 491

Step 2:
39 divided by 491 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 491

Let's proceed to step 3:
The number 491 fits into 394 0 times, leaving a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 394, we get 394.
Grab the next digit (5) from the dividend, add it to 394, then carry on: 3945 / 491

Advancing to step 4:
491 can be fit into 3945 8 times, resulting in a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 3928 from 3945 and we're left with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 491

Advancing to step 5:
491 can be fit into 178 0 times, resulting in a remainder of 178.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 178 to get 178.
Take the next digit (1) from the dividend and append it to 178, then repeat: 1781 / 491

Step 6:
491 goes into 1781 3 times with a remainder of 308.
The number 3 becomes the next digit in our result. 
Result so far: 803.0
If we take 1473 away from 1781, we end up with 308.
Take the next digit (7) from the dividend and append it to 308, then repeat: 3087 / 491

Let's proceed to step 7:
If we divide 3087 by 491, we get 6 and a remainder of 141.
Use 6 as the next digit of our solution. 
Result so far: 8036.0
Deduct 2946 from 3087 and we're left with 141.
Take the next digit (2) from the dividend and append it to 141, then repeat: 1412 / 491

Moving on to step 8:
491 goes into 1412 2 times with a remainder of 430.
Use 2 as the next digit of our solution. 
Result so far: 80362.0
Subtract 982 from 1412 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 9:
491 can be fit into 4300 8 times, resulting in a remainder of 372.
Write down 8 as next digit of the result. 
Result so far: 80362.8
Deduct 3928 from 4300 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 10:
When dividing 3720 by 491, we get 7 with a remainder of 283.
Use 7 as the next digit of our solution. 
Result so far: 80362.87
If we subtract 3437 from 3720, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Let's proceed to step 11:
The number 491 fits into 2830 5 times, leaving a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 80362.875
The remainder is 375 after subtracting 2455 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 12:
The number 491 fits into 3750 7 times, leaving a remainder of 313.
Record the quotient 7 as the next digit in the result. 
Result so far: 80362.8757
The remainder is 313 after subtracting 3437 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 13:
3130 divided by 491 is 6 with a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 80362.87576
Deduct 2946 from 3130 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 14:
If we divide 1840 by 491, we get 3 and a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 80362.875763
If we subtract 1473 from 1840, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 15:
491 can be fit into 3670 7 times, resulting in a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 80362.8757637
Deduct 3437 from 3670 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 16:
2330 divided by 491 is 4 with a remainder of 366.
The next digit of our result is 4. 
Result so far: 80362.87576374
If we subtract 1964 from 2330, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The final result is 80362.87576374 with a remainder of 3.66e-07.
