We're dividing 347437 by 45 
The aim is to understand the frequency of 45 in 347437.

Going ahead to step 1:
3 divided by 45 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 45

Let's proceed to step 2:
45 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 45

On to step 3:
The number 45 fits into 347 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 7.0
If we take 315 away from 347, we end up with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 45

Advancing to step 4:
45 goes into 324 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtract 315 from 324 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 45

On to step 5:
45 can be fit into 93 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 772.0
If we take 90 away from 93, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 45

On to step 6:
The number 45 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 7720.0
Subtract 0 from 37 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
45 can be fit into 370 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 7720.8
Subtract 360 from 370 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.

On to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 7720.82
Deduct 90 from 100 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.

Step 9:
If we divide 100 by 45, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 7720.822
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.

The quotient of the division is 7720.822, and the remainder is 0.001.
