606852 ÷ 40 
The aim is to understand the frequency of 40 in 606852.

On to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 40

Going ahead to step 2:
The number 40 fits into 60 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 40 from 60 to get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 40

Let's proceed to step 3:
If we divide 206 by 40, we get 5 and a remainder of 6.
The next digit of our result is 5. 
Result so far: 15.0
If we take 200 away from 206, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 40

Let's proceed to step 4:
If we divide 68 by 40, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we subtract 40 from 68, we get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 40

On to step 5:
If we divide 285 by 40, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1517.0
Deduct 280 from 285 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 40

Moving on to step 6:
The number 40 fits into 52 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 15171.0
If we subtract 40 from 52, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
40 can be fit into 120 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 15171.3
Subtracting 120 from 120 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15171.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15171.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 15171.3 with a remaining 0.0.
