We look at the division of 81962087 by 747 
The aim is to understand the frequency of 747 in 81962087.

Step 1:
The number 747 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 747

Moving on to step 2:
The number 747 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 747

Advancing to step 3:
The number 747 fits into 819 1 times, leaving a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 747 from 819 leaves us with 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 747

Advancing to step 4:
726 divided by 747 is 0 with a remainder of 726.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 726, we end up with 726.
Take the next digit (2) from the dividend and append it to 726, then repeat: 7262 / 747

On to step 5:
747 can be fit into 7262 9 times, resulting in a remainder of 539.
The next digit of our result is 9. 
Result so far: 109.0
The remainder is 539 after subtracting 6723 from 7262.
Grab the next digit (0) from the dividend, add it to 539, then carry on: 5390 / 747

Going ahead to step 6:
When dividing 5390 by 747, we get 7 with a remainder of 161.
Record the quotient 7 as the next digit in the result. 
Result so far: 1097.0
If we take 5229 away from 5390, we end up with 161.
Bring next digit (8) of the dividend behind the 161 and repeat the process: 1618 / 747

Advancing to step 7:
1618 divided by 747 is 2 with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 10972.0
Subtracting 1494 from 1618 leaves us with 124.
Take the next digit (7) from the dividend and append it to 124, then repeat: 1247 / 747

Going ahead to step 8:
When dividing 1247 by 747, we get 1 with a remainder of 500.
The next digit of our result is 1. 
Result so far: 109721.0
Subtract 747 from 1247 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 9:
If we divide 5000 by 747, we get 6 and a remainder of 518.
Use 6 as the next digit of our solution. 
Result so far: 109721.6
Subtract 4482 from 5000 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 10:
The number 747 fits into 5180 6 times, leaving a remainder of 698.
Put 6 as the next digit of the answer. 
Result so far: 109721.66
The remainder is 698 after subtracting 4482 from 5180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

After the division, we end up with 109721.66 and a remainder of 0.698.
