Let's divide 643735 by 62
The aim is to understand the frequency of 62 in 643735.

Let's proceed to step 1:
When dividing 6 by 62, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 62

Moving on to step 2:
The number 62 fits into 64 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 62 from 64, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 62

Moving on to step 3:
If we divide 23 by 62, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 62

Going ahead to step 4:
The number 62 fits into 237 3 times, leaving a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we take 186 away from 237, we end up with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 62

Going ahead to step 5:
62 can be fit into 513 8 times, resulting in a remainder of 17.
The next digit of our result is 8. 
Result so far: 1038.0
If we take 496 away from 513, we end up with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 62

Step 6:
The number 62 fits into 175 2 times, leaving a remainder of 51.
The next digit of our result is 2. 
Result so far: 10382.0
Deduct 124 from 175 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
62 can be fit into 510 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 10382.8
Deduct 496 from 510 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
140 divided by 62 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 10382.82
Deduct 124 from 140 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 62 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 10382.822
Subtracting 124 from 160 leaves us with 36.
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 result is 10382.822 with a remainder of 0.0036.
