Let's divide 40067509 by 407
The aim is to understand the frequency of 407 in 40067509.

Advancing to step 1:
The number 407 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 407

Let's proceed to step 2:
407 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 407

Step 3:
407 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Grab the next digit (6) from the dividend, add it to 400, then carry on: 4006 / 407

On to step 4:
407 can be fit into 4006 9 times, resulting in a remainder of 343.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 3663 from 4006 leaves us with 343.
Fetch the next digit (7) from the dividend, attach it to 343 and continue: 3437 / 407

Let's proceed to step 5:
407 goes into 3437 8 times with a remainder of 181.
The next digit of our result is 8. 
Result so far: 98.0
Subtract 3256 from 3437 to get 181.
Fetch the next digit (5) from the dividend, attach it to 181 and continue: 1815 / 407

Advancing to step 6:
407 goes into 1815 4 times with a remainder of 187.
Record the quotient 4 as the next digit in the result. 
Result so far: 984.0
Deduct 1628 from 1815 and we're left with 187.
Take the next digit (0) from the dividend and append it to 187, then repeat: 1870 / 407

On to step 7:
407 goes into 1870 4 times with a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 9844.0
Deduct 1628 from 1870 and we're left with 242.
Fetch the next digit (9) from the dividend, attach it to 242 and continue: 2429 / 407

Let's proceed to step 8:
407 can be fit into 2429 5 times, resulting in a remainder of 394.
Use 5 as the next digit of our solution. 
Result so far: 98445.0
The remainder is 394 after subtracting 2035 from 2429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 9:
3940 divided by 407 is 9 with a remainder of 277.
The next digit of our result is 9. 
Result so far: 98445.9
The remainder is 277 after subtracting 3663 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 10:
407 goes into 2770 6 times with a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 98445.96
Subtract 2442 from 2770 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 11:
If we divide 3280 by 407, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 98445.968
Subtract 3256 from 3280 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
The number 407 fits into 240 0 times, leaving a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 98445.968
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
If we divide 2400 by 407, we get 5 and a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 98445.96805
Deduct 2035 from 2400 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 14:
If we divide 3650 by 407, we get 8 and a remainder of 394.
The number 8 becomes the next digit in our result. 
Result so far: 98445.968058
The remainder is 394 after subtracting 3256 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 15:
3940 divided by 407 is 9 with a remainder of 277.
Record the quotient 9 as the next digit in the result. 
Result so far: 98445.9680589
Subtracting 3663 from 3940 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

On to step 16:
407 can be fit into 2770 6 times, resulting in a remainder of 328.
Use 6 as the next digit of our solution. 
Result so far: 98445.96805896
Deduct 2442 from 2770 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

In conclusion, the division gives 98445.96805896 with a balance of 3.28e-07.
