We divide 209841 by 40
The aim is to understand the frequency of 40 in 209841.

Advancing to step 1:
When dividing 2 by 40, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 40

Moving on to step 2:
40 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 40

On to step 3:
If we divide 209 by 40, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 200 from 209 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 40

Let's proceed to step 4:
40 goes into 98 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 80 from 98 leaves us with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 40

Advancing to step 5:
If we divide 184 by 40, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 524.0
Subtracting 160 from 184 leaves us with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 40

Going ahead to step 6:
When dividing 241 by 40, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 5246.0
Deduct 240 from 241 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 40 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5246.0
Subtracting 0 from 10 leaves us 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.

Advancing to step 8:
40 goes into 100 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 5246.02
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5246.025
If we take 200 away from 200, we end up 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.

Let's proceed to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5246.025
Subtracting 0 from 0 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.

Going ahead to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5246.025
Subtract 0 from 0 to 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.

The final outcome is 5246.025, with a leftover of 0.0.
