931000 ÷ 454 
The aim is to understand the frequency of 454 in 931000.

Step 1:
9 divided by 454 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 454

Step 2:
When dividing 93 by 454, we get 0 with a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 93, we end up with 93.
Fetch the next digit (1) from the dividend, attach it to 93 and continue: 931 / 454

On to step 3:
931 divided by 454 is 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 908 away from 931, we end up with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 454

On to step 4:
When dividing 230 by 454, we get 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 230 after subtracting 0 from 230.
Grab the next digit (0) from the dividend, add it to 230, then carry on: 2300 / 454

Step 5:
454 goes into 2300 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 205.0
Subtract 2270 from 2300 to get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 454

Step 6:
300 divided by 454 is 0 with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 2050.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 7:
If we divide 3000 by 454, we get 6 and a remainder of 276.
Put 6 as the next digit of the answer. 
Result so far: 2050.6
Subtracting 2724 from 3000 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 8:
454 can be fit into 2760 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 2050.66
The remainder is 36 after subtracting 2724 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 2050.66, and the remainder is 0.036.
