50224312 divided by 401 
The aim is to understand the frequency of 401 in 50224312.

On to step 1:
5 divided by 401 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 401

Advancing to step 2:
401 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 401

Step 3:
401 can be fit into 502 1 times, resulting in a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 101 after subtracting 401 from 502.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 401

Step 4:
401 can be fit into 1012 2 times, resulting in a remainder of 210.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 802 away from 1012, we end up with 210.
Grab the next digit (4) from the dividend, add it to 210, then carry on: 2104 / 401

On to step 5:
401 can be fit into 2104 5 times, resulting in a remainder of 99.
Use 5 as the next digit of our solution. 
Result so far: 125.0
If we subtract 2005 from 2104, we get 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 401

Let's proceed to step 6:
When dividing 993 by 401, we get 2 with a remainder of 191.
The next digit of our result is 2. 
Result so far: 1252.0
If we subtract 802 from 993, we get 191.
Append the next digit (1) from the dividend to 191 and continue with: 1911 / 401

Going ahead to step 7:
When dividing 1911 by 401, we get 4 with a remainder of 307.
Record the quotient 4 as the next digit in the result. 
Result so far: 12524.0
Deduct 1604 from 1911 and we're left with 307.
Take the next digit (2) from the dividend and append it to 307, then repeat: 3072 / 401

Going ahead to step 8:
When dividing 3072 by 401, we get 7 with a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 125247.0
Subtracting 2807 from 3072 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 9:
401 goes into 2650 6 times with a remainder of 244.
Record the quotient 6 as the next digit in the result. 
Result so far: 125247.6
If we subtract 2406 from 2650, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 10:
401 goes into 2440 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 125247.66
The remainder is 34 after subtracting 2406 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 125247.66, with a leftover of 0.034.
