We divide 81340507 by 45
The aim is to understand the frequency of 45 in 81340507.

Step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 45

Advancing to step 2:
81 divided by 45 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 81 to get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 45

Step 3:
The number 45 fits into 363 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 360 from 363 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 45

Advancing to step 4:
The number 45 fits into 34 0 times, leaving a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Subtract 0 from 34 to get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 45

On to step 5:
340 divided by 45 is 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 1807.0
If we subtract 315 from 340, we get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 45

Moving on to step 6:
45 goes into 255 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 18075.0
If we subtract 225 from 255, we get 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 45

Step 7:
300 divided by 45 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 180756.0
Subtract 270 from 300 to get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 45

Let's proceed to step 8:
When dividing 307 by 45, we get 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 1807566.0
If we take 270 away from 307, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
When dividing 370 by 45, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1807566.8
The remainder is 10 after subtracting 360 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 45 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1807566.82
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 45, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1807566.822
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.

The final result is 1807566.822 with a remainder of 0.001.
