257787 divided by 40 
The aim is to understand the frequency of 40 in 257787.

Advancing to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 40

Let's proceed to step 2:
40 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 40

Advancing to step 3:
If we divide 257 by 40, we get 6 and a remainder of 17.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 240 from 257, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 40

Step 4:
40 can be fit into 177 4 times, resulting in a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 160 from 177 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 40

Going ahead to step 5:
The number 40 fits into 178 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 644.0
Subtract 160 from 178 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 40

Going ahead to step 6:
40 goes into 187 4 times with a remainder of 27.
The next digit of our result is 4. 
Result so far: 6444.0
Subtract 160 from 187 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
40 can be fit into 270 6 times, resulting in a remainder of 30.
The next digit of our result is 6. 
Result so far: 6444.6
If we subtract 240 from 270, we 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 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 6444.67
If we subtract 280 from 300, we 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.

Let's proceed to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6444.675
The remainder is 0 after subtracting 200 from 200.
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 10:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6444.675
If we take 0 away from 0, 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.

Step 11:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6444.675
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.

The final result is 6444.675 with a remainder of 0.0.
