Let's divide 61366851 by 491
The aim is to understand the frequency of 491 in 61366851.

Step 1:
If we divide 6 by 491, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 491

Going ahead to step 2:
491 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 491

Advancing to step 3:
491 goes into 613 1 times with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 491 from 613 and we're left with 122.
Append the next digit (6) from the dividend to 122 and continue with: 1226 / 491

Moving on to step 4:
When dividing 1226 by 491, we get 2 with a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 982 from 1226, we get 244.
Include the next digit (6) from the dividend after 244, then repeat: 2446 / 491

Step 5:
491 goes into 2446 4 times with a remainder of 482.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Deduct 1964 from 2446 and we're left with 482.
Grab the next digit (8) from the dividend, add it to 482, then carry on: 4828 / 491

Step 6:
491 goes into 4828 9 times with a remainder of 409.
The next digit of our result is 9. 
Result so far: 1249.0
Subtract 4419 from 4828 to get 409.
Grab the next digit (5) from the dividend, add it to 409, then carry on: 4095 / 491

Going ahead to step 7:
If we divide 4095 by 491, we get 8 and a remainder of 167.
Record the quotient 8 as the next digit in the result. 
Result so far: 12498.0
Deduct 3928 from 4095 and we're left with 167.
Grab the next digit (1) from the dividend, add it to 167, then carry on: 1671 / 491

Going ahead to step 8:
491 goes into 1671 3 times with a remainder of 198.
Write down 3 as next digit of the result. 
Result so far: 124983.0
Subtract 1473 from 1671 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 9:
1980 divided by 491 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 124983.4
If we take 1964 away from 1980, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
491 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 124983.4
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
1600 divided by 491 is 3 with a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 124983.403
The remainder is 127 after subtracting 1473 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 12:
The number 491 fits into 1270 2 times, leaving a remainder of 288.
The number 2 becomes the next digit in our result. 
Result so far: 124983.4032
If we take 982 away from 1270, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 13:
2880 divided by 491 is 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 124983.40325
Subtract 2455 from 2880 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 14:
If we divide 4250 by 491, we get 8 and a remainder of 322.
The number 8 becomes the next digit in our result. 
Result so far: 124983.403258
The remainder is 322 after subtracting 3928 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 15:
The number 491 fits into 3220 6 times, leaving a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 124983.4032586
The remainder is 274 after subtracting 2946 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 16:
491 can be fit into 2740 5 times, resulting in a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 124983.40325865
Subtract 2455 from 2740 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The quotient of the division is 124983.40325865, and the remainder is 2.85e-07.
