911357 divided by 45 
The aim is to understand the frequency of 45 in 911357.

Advancing to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 45

Going ahead to step 2:
91 divided by 45 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 90 from 91 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 45

On to step 3:
11 divided by 45 is 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 11 to get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 45

Let's proceed to step 4:
113 divided by 45 is 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtracting 90 from 113 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 45

Let's proceed to step 5:
When dividing 235 by 45, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2025.0
Deduct 225 from 235 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 45

Let's proceed to step 6:
107 divided by 45 is 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 20252.0
If we take 90 away from 107, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
45 goes into 170 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 20252.3
If we take 135 away from 170, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
45 goes into 350 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 20252.37
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 20252.377
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 20252.377, and the remainder is 0.0035.
