Let's divide 86721094 by 462
The aim is to understand the frequency of 462 in 86721094.

Moving on to step 1:
462 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 462

Moving on to step 2:
86 divided by 462 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 462

Advancing to step 3:
867 divided by 462 is 1 with a remainder of 405.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 462 from 867 leaves us with 405.
Take the next digit (2) from the dividend and append it to 405, then repeat: 4052 / 462

Let's proceed to step 4:
When dividing 4052 by 462, we get 8 with a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 3696 from 4052 to get 356.
Bring next digit (1) of the dividend behind the 356 and repeat the process: 3561 / 462

Let's proceed to step 5:
3561 divided by 462 is 7 with a remainder of 327.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtract 3234 from 3561 to get 327.
Grab the next digit (0) from the dividend, add it to 327, then carry on: 3270 / 462

On to step 6:
462 can be fit into 3270 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 1877.0
The remainder is 36 after subtracting 3234 from 3270.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 462

Moving on to step 7:
If we divide 369 by 462, we get 0 and a remainder of 369.
Record the quotient 0 as the next digit in the result. 
Result so far: 18770.0
Subtract 0 from 369 to get 369.
Append the next digit (4) from the dividend to 369 and continue with: 3694 / 462

Moving on to step 8:
3694 divided by 462 is 7 with a remainder of 460.
Use 7 as the next digit of our solution. 
Result so far: 187707.0
Subtracting 3234 from 3694 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 9:
If we divide 4600 by 462, we get 9 and a remainder of 442.
Use 9 as the next digit of our solution. 
Result so far: 187707.9
If we take 4158 away from 4600, we end up with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 10:
4420 divided by 462 is 9 with a remainder of 262.
Use 9 as the next digit of our solution. 
Result so far: 187707.99
The remainder is 262 after subtracting 4158 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

The final result is 187707.99 with a remainder of 0.262.
