45236294 divided by 407 
The aim is to understand the frequency of 407 in 45236294.

Going ahead to step 1:
If we divide 4 by 407, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 407

Moving on to step 2:
The number 407 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 407

On to step 3:
When dividing 452 by 407, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 407 from 452 to get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 407

Advancing to step 4:
407 goes into 453 1 times with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 407 from 453, we get 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 407

Let's proceed to step 5:
407 can be fit into 466 1 times, resulting in a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 111.0
If we subtract 407 from 466, we get 59.
Append the next digit (2) from the dividend to 59 and continue with: 592 / 407

Step 6:
407 can be fit into 592 1 times, resulting in a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 1111.0
The remainder is 185 after subtracting 407 from 592.
Include the next digit (9) from the dividend after 185, then repeat: 1859 / 407

Advancing to step 7:
1859 divided by 407 is 4 with a remainder of 231.
Record the quotient 4 as the next digit in the result. 
Result so far: 11114.0
The remainder is 231 after subtracting 1628 from 1859.
Fetch the next digit (4) from the dividend, attach it to 231 and continue: 2314 / 407

On to step 8:
407 goes into 2314 5 times with a remainder of 279.
Put 5 as the next digit of the answer. 
Result so far: 111145.0
Subtract 2035 from 2314 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 9:
2790 divided by 407 is 6 with a remainder of 348.
Write down 6 as next digit of the result. 
Result so far: 111145.6
Deduct 2442 from 2790 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 10:
407 can be fit into 3480 8 times, resulting in a remainder of 224.
The next digit of our result is 8. 
Result so far: 111145.68
Subtracting 3256 from 3480 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 11:
When dividing 2240 by 407, we get 5 with a remainder of 205.
The next digit of our result is 5. 
Result so far: 111145.685
Deduct 2035 from 2240 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 12:
2050 divided by 407 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 111145.6855
The remainder is 15 after subtracting 2035 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 111145.6855, with a leftover of 0.00015.
