Let's divide 711138 by 45
The aim is to understand the frequency of 45 in 711138.

On to step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 45

Going ahead to step 2:
45 can be fit into 71 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 71 and we're left with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 45

Let's proceed to step 3:
45 goes into 261 5 times with a remainder of 36.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 36 after subtracting 225 from 261.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 45

Going ahead to step 4:
45 can be fit into 361 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 1 after subtracting 360 from 361.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 45

Going ahead to step 5:
The number 45 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 1580.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 45

Going ahead to step 6:
The number 45 fits into 138 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 15803.0
If we take 135 away from 138, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 45, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 15803.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 45, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 15803.06
The remainder is 30 after subtracting 270 from 300.
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 9:
300 divided by 45 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 15803.066
If we take 270 away from 300, we end up with 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 final outcome is 15803.066, with a leftover of 0.003.
