We divide 43633036 by 407
The aim is to understand the frequency of 407 in 43633036.

Advancing to step 1:
407 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 407

Moving on to step 2:
43 divided by 407 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 407

Going ahead to step 3:
407 can be fit into 436 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 407 from 436 and we're left with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 407

Step 4:
407 can be fit into 293 0 times, resulting in a remainder of 293.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 293 to get 293.
Bring next digit (3) of the dividend behind the 293 and repeat the process: 2933 / 407

Let's proceed to step 5:
The number 407 fits into 2933 7 times, leaving a remainder of 84.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we subtract 2849 from 2933, we get 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 407

Moving on to step 6:
When dividing 840 by 407, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1072.0
If we subtract 814 from 840, we get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 407

Going ahead to step 7:
If we divide 263 by 407, we get 0 and a remainder of 263.
Record the quotient 0 as the next digit in the result. 
Result so far: 10720.0
Subtract 0 from 263 to get 263.
Append the next digit (6) from the dividend to 263 and continue with: 2636 / 407

Going ahead to step 8:
If we divide 2636 by 407, we get 6 and a remainder of 194.
The number 6 becomes the next digit in our result. 
Result so far: 107206.0
Deduct 2442 from 2636 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 9:
407 can be fit into 1940 4 times, resulting in a remainder of 312.
The next digit of our result is 4. 
Result so far: 107206.4
Subtract 1628 from 1940 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 10:
The number 407 fits into 3120 7 times, leaving a remainder of 271.
Put 7 as the next digit of the answer. 
Result so far: 107206.47
If we take 2849 away from 3120, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 11:
If we divide 2710 by 407, we get 6 and a remainder of 268.
Write down 6 as next digit of the result. 
Result so far: 107206.476
If we take 2442 away from 2710, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 12:
2680 divided by 407 is 6 with a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 107206.4766
If we subtract 2442 from 2680, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 107206.4766 and a remainder of 0.00238.
