Let's divide 374092 by 81
The aim is to understand the frequency of 81 in 374092.

Advancing to step 1:
81 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 subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 81

Going ahead to step 2:
If we divide 37 by 81, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 81

On to step 3:
The number 81 fits into 374 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 50 after subtracting 324 from 374.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 81

Going ahead to step 4:
If we divide 500 by 81, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 486 from 500, we get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 81

Let's proceed to step 5:
The number 81 fits into 149 1 times, leaving a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 461.0
Subtract 81 from 149 to get 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 81

Going ahead to step 6:
The number 81 fits into 682 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 4618.0
If we subtract 648 from 682, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
When dividing 340 by 81, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4618.4
If we take 324 away from 340, 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 8:
81 goes into 160 1 times with a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 4618.41
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 9:
If we divide 790 by 81, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 4618.419
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
81 goes into 610 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 4618.4197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 11:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4618.41975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
81 goes into 250 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4618.419753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
If we divide 70 by 81, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 4618.419753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
When dividing 700 by 81, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 4618.41975308
Subtracting 648 from 700 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 4618.41975308 with a remainder of 5.2e-08.
