680716 divided by 45 
The aim is to understand the frequency of 45 in 680716.

Let's proceed to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 45

Let's proceed to step 2:
When dividing 68 by 45, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 68 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 45

Let's proceed to step 3:
230 divided by 45 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 225 from 230, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 45

Let's proceed to step 4:
45 goes into 57 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtracting 45 from 57 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 45

Step 5:
121 divided by 45 is 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 1512.0
The remainder is 31 after subtracting 90 from 121.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 45

On to step 6:
45 can be fit into 316 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 15127.0
Deduct 315 from 316 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 45, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15127.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 15127.02
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 45 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 15127.022
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 15127.022 with a remaining 0.001.
