Let's divide 628768 by 45
The aim is to understand the frequency of 45 in 628768.

On to step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 45

Step 2:
62 divided by 45 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 45 from 62.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 45

On to step 3:
45 goes into 178 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 135 from 178, we get 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 45

Advancing to step 4:
When dividing 437 by 45, we get 9 with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we take 405 away from 437, we end up with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 45

Advancing to step 5:
If we divide 326 by 45, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 1397.0
Deduct 315 from 326 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 45

Let's proceed to step 6:
If we divide 118 by 45, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 13972.0
The remainder is 28 after subtracting 90 from 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 45 fits into 280 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 13972.6
If we subtract 270 from 280, we 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.

Advancing to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 13972.62
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.

Going ahead to step 9:
45 goes into 100 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 13972.622
If we subtract 90 from 100, we 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.

After the division, we end up with 13972.622 and a remainder of 0.001.
