We're dividing 9446123 by 401 
The aim is to understand the frequency of 401 in 9446123.

Step 1:
401 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 401

On to step 2:
401 can be fit into 94 0 times, resulting in a remainder of 94.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 94 after subtracting 0 from 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 401

On to step 3:
The number 401 fits into 944 2 times, leaving a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 802 from 944 to get 142.
Append the next digit (6) from the dividend to 142 and continue with: 1426 / 401

Step 4:
1426 divided by 401 is 3 with a remainder of 223.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 1203 from 1426 leaves us with 223.
Take the next digit (1) from the dividend and append it to 223, then repeat: 2231 / 401

Advancing to step 5:
2231 divided by 401 is 5 with a remainder of 226.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
The remainder is 226 after subtracting 2005 from 2231.
Include the next digit (2) from the dividend after 226, then repeat: 2262 / 401

Going ahead to step 6:
401 can be fit into 2262 5 times, resulting in a remainder of 257.
The number 5 becomes the next digit in our result. 
Result so far: 2355.0
If we subtract 2005 from 2262, we get 257.
Fetch the next digit (3) from the dividend, attach it to 257 and continue: 2573 / 401

Moving on to step 7:
The number 401 fits into 2573 6 times, leaving a remainder of 167.
Record the quotient 6 as the next digit in the result. 
Result so far: 23556.0
Subtracting 2406 from 2573 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 8:
1670 divided by 401 is 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 23556.4
If we take 1604 away from 1670, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
When dividing 660 by 401, we get 1 with a remainder of 259.
The next digit of our result is 1. 
Result so far: 23556.41
Subtract 401 from 660 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Let's proceed to step 10:
The number 401 fits into 2590 6 times, leaving a remainder of 184.
The next digit of our result is 6. 
Result so far: 23556.416
If we take 2406 away from 2590, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 11:
401 can be fit into 1840 4 times, resulting in a remainder of 236.
Write down 4 as next digit of the result. 
Result so far: 23556.4164
The remainder is 236 after subtracting 1604 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 12:
401 can be fit into 2360 5 times, resulting in a remainder of 355.
The number 5 becomes the next digit in our result. 
Result so far: 23556.41645
The remainder is 355 after subtracting 2005 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 13:
401 can be fit into 3550 8 times, resulting in a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 23556.416458
If we subtract 3208 from 3550, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

On to step 14:
The number 401 fits into 3420 8 times, leaving a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 23556.4164588
Deduct 3208 from 3420 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 23556.4164588 with a remainder of 2.12e-06.
