747840 ÷ 53 
The aim is to understand the frequency of 53 in 747840.

Going ahead to step 1:
If we divide 7 by 53, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 53

Step 2:
The number 53 fits into 74 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 21 after subtracting 53 from 74.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 53

Let's proceed to step 3:
If we divide 217 by 53, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 212 from 217, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 53

Advancing to step 4:
53 can be fit into 58 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
If we take 53 away from 58, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 53

Going ahead to step 5:
When dividing 54 by 53, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1411.0
If we take 53 away from 54, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 53

On to step 6:
When dividing 10 by 53, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14110.0
Subtract 0 from 10 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.

Advancing to step 7:
53 goes into 100 1 times with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 14110.1
If we subtract 53 from 100, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
The number 53 fits into 470 8 times, leaving a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 14110.18
The remainder is 46 after subtracting 424 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
53 goes into 460 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 14110.188
The remainder is 36 after subtracting 424 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 14110.188, with a leftover of 0.0036.
