We're dividing 80037472 by 407 
The aim is to understand the frequency of 407 in 80037472.

Going ahead to step 1:
If we divide 8 by 407, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 407

Moving on to step 2:
When dividing 80 by 407, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 407

Let's proceed to step 3:
407 goes into 800 1 times with a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 393 after subtracting 407 from 800.
Append the next digit (3) from the dividend to 393 and continue with: 3933 / 407

On to step 4:
3933 divided by 407 is 9 with a remainder of 270.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 3663 away from 3933, we end up with 270.
Fetch the next digit (7) from the dividend, attach it to 270 and continue: 2707 / 407

On to step 5:
407 can be fit into 2707 6 times, resulting in a remainder of 265.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
If we subtract 2442 from 2707, we get 265.
Take the next digit (4) from the dividend and append it to 265, then repeat: 2654 / 407

Moving on to step 6:
407 can be fit into 2654 6 times, resulting in a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 1966.0
The remainder is 212 after subtracting 2442 from 2654.
Fetch the next digit (7) from the dividend, attach it to 212 and continue: 2127 / 407

Let's proceed to step 7:
When dividing 2127 by 407, we get 5 with a remainder of 92.
The next digit of our result is 5. 
Result so far: 19665.0
Subtract 2035 from 2127 to get 92.
Take the next digit (2) from the dividend and append it to 92, then repeat: 922 / 407

Moving on to step 8:
407 can be fit into 922 2 times, resulting in a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 196652.0
If we subtract 814 from 922, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 9:
1080 divided by 407 is 2 with a remainder of 266.
The next digit of our result is 2. 
Result so far: 196652.2
Subtract 814 from 1080 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 10:
If we divide 2660 by 407, we get 6 and a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 196652.26
If we subtract 2442 from 2660, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 11:
When dividing 2180 by 407, we get 5 with a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 196652.265
Subtracting 2035 from 2180 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 12:
When dividing 1450 by 407, we get 3 with a remainder of 229.
Write down 3 as next digit of the result. 
Result so far: 196652.2653
The remainder is 229 after subtracting 1221 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 13:
When dividing 2290 by 407, we get 5 with a remainder of 255.
The next digit of our result is 5. 
Result so far: 196652.26535
If we subtract 2035 from 2290, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 14:
The number 407 fits into 2550 6 times, leaving a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 196652.265356
Subtract 2442 from 2550 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 15:
407 can be fit into 1080 2 times, resulting in a remainder of 266.
Record the quotient 2 as the next digit in the result. 
Result so far: 196652.2653562
Deduct 814 from 1080 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 16:
407 can be fit into 2660 6 times, resulting in a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 196652.26535626
If we take 2442 away from 2660, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Our division results in 196652.26535626 with a remaining 2.18e-07.
