72911563 divided by 492 
The aim is to understand the frequency of 492 in 72911563.

Going ahead to step 1:
When dividing 7 by 492, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 492

Going ahead to step 2:
492 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 492

Moving on to step 3:
When dividing 729 by 492, we get 1 with a remainder of 237.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 492 away from 729, we end up with 237.
Grab the next digit (1) from the dividend, add it to 237, then carry on: 2371 / 492

Moving on to step 4:
492 goes into 2371 4 times with a remainder of 403.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 1968 away from 2371, we end up with 403.
Append the next digit (1) from the dividend to 403 and continue with: 4031 / 492

On to step 5:
492 can be fit into 4031 8 times, resulting in a remainder of 95.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we subtract 3936 from 4031, we get 95.
Take the next digit (5) from the dividend and append it to 95, then repeat: 955 / 492

Let's proceed to step 6:
492 can be fit into 955 1 times, resulting in a remainder of 463.
Write down 1 as next digit of the result. 
Result so far: 1481.0
If we take 492 away from 955, we end up with 463.
Grab the next digit (6) from the dividend, add it to 463, then carry on: 4636 / 492

Advancing to step 7:
4636 divided by 492 is 9 with a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 14819.0
If we subtract 4428 from 4636, we get 208.
Include the next digit (3) from the dividend after 208, then repeat: 2083 / 492

Step 8:
If we divide 2083 by 492, we get 4 and a remainder of 115.
The next digit of our result is 4. 
Result so far: 148194.0
Subtract 1968 from 2083 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 9:
492 goes into 1150 2 times with a remainder of 166.
Put 2 as the next digit of the answer. 
Result so far: 148194.2
Deduct 984 from 1150 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 10:
When dividing 1660 by 492, we get 3 with a remainder of 184.
The number 3 becomes the next digit in our result. 
Result so far: 148194.23
If we subtract 1476 from 1660, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
492 goes into 1840 3 times with a remainder of 364.
Put 3 as the next digit of the answer. 
Result so far: 148194.233
The remainder is 364 after subtracting 1476 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 148194.233 with a remainder of 0.0364.
