922836 ÷ 45 
The aim is to understand the frequency of 45 in 922836.

On to step 1:
9 divided by 45 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 45

On to step 2:
If we divide 92 by 45, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 90 from 92.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 45

Going ahead to step 3:
The number 45 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 45

Advancing to step 4:
228 divided by 45 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
Subtract 225 from 228 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 45

Advancing to step 5:
The number 45 fits into 33 0 times, leaving a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 2050.0
If we take 0 away from 33, we end up with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 45

On to step 6:
When dividing 336 by 45, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 20507.0
Subtracting 315 from 336 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
45 can be fit into 210 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 20507.4
The remainder is 30 after subtracting 180 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 20507.46
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 20507.466
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 20507.466, and the remainder is 0.003.
