We're dividing 653646 by 68 
The aim is to understand the frequency of 68 in 653646.

Moving on to step 1:
If we divide 6 by 68, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 68

Advancing to step 2:
When dividing 65 by 68, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 68

Advancing to step 3:
If we divide 653 by 68, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 612 away from 653, we end up with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 68

Advancing to step 4:
When dividing 416 by 68, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtract 408 from 416 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 68

Let's proceed to step 5:
68 can be fit into 84 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 961.0
Deduct 68 from 84 and we're left with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 68

On to step 6:
166 divided by 68 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 9612.0
Subtract 136 from 166 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 68, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 9612.4
If we take 272 away from 300, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
The number 68 fits into 280 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 9612.44
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 9612.44, and the remainder is 0.008.
