616071 divided by 45 
The aim is to understand the frequency of 45 in 616071.

Going ahead to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 45

On to step 2:
The number 45 fits into 61 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 61, we get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 45

Step 3:
166 divided by 45 is 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 135 from 166 leaves us with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 45

Going ahead to step 4:
The number 45 fits into 310 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we take 270 away from 310, we end up with 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 45

Advancing to step 5:
When dividing 407 by 45, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 1369.0
Deduct 405 from 407 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 45

Advancing to step 6:
When dividing 21 by 45, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 13690.0
Subtracting 0 from 21 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.

Moving on to step 7:
The number 45 fits into 210 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 13690.4
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.

Going ahead to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 13690.46
If we subtract 270 from 300, we 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.

Step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 13690.466
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.

Our division results in 13690.466 with a remaining 0.003.
