We're dividing 84307759 by 40 
The aim is to understand the frequency of 40 in 84307759.

Let's proceed to step 1:
When dividing 8 by 40, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 40

Step 2:
When dividing 84 by 40, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 4 after subtracting 80 from 84.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 40

Moving on to step 3:
When dividing 43 by 40, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 40 away from 43, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 40

Advancing to step 4:
If we divide 30 by 40, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 40

On to step 5:
When dividing 307 by 40, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 2107.0
Deduct 280 from 307 and we're left with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 40

On to step 6:
277 divided by 40 is 6 with a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 21076.0
Deduct 240 from 277 and we're left with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 40

Going ahead to step 7:
40 goes into 375 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 210769.0
Subtracting 360 from 375 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 40

Going ahead to step 8:
159 divided by 40 is 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 2107693.0
Deduct 120 from 159 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
When dividing 390 by 40, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 2107693.9
If we subtract 360 from 390, 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.

Advancing to step 10:
40 goes into 300 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 2107693.97
Subtract 280 from 300 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 11:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2107693.975
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.

Let's proceed to step 12:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2107693.975
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.

On to step 13:
When dividing 0 by 40, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2107693.975
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.

After the division, we end up with 2107693.975 and a remainder of 0.0.
