We're dividing 48016420 by 350 
The aim is to understand the frequency of 350 in 48016420.

On to step 1:
350 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 350

Moving on to step 2:
350 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 350

Advancing to step 3:
The number 350 fits into 480 1 times, leaving a remainder of 130.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 350 from 480 leaves us with 130.
Grab the next digit (1) from the dividend, add it to 130, then carry on: 1301 / 350

Step 4:
If we divide 1301 by 350, we get 3 and a remainder of 251.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1050 from 1301 leaves us with 251.
Include the next digit (6) from the dividend after 251, then repeat: 2516 / 350

Advancing to step 5:
If we divide 2516 by 350, we get 7 and a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 66 after subtracting 2450 from 2516.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 350

Step 6:
664 divided by 350 is 1 with a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 1371.0
Subtract 350 from 664 to get 314.
Grab the next digit (2) from the dividend, add it to 314, then carry on: 3142 / 350

Let's proceed to step 7:
350 can be fit into 3142 8 times, resulting in a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 13718.0
If we subtract 2800 from 3142, we get 342.
Grab the next digit (0) from the dividend, add it to 342, then carry on: 3420 / 350

Going ahead to step 8:
3420 divided by 350 is 9 with a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 137189.0
Deduct 3150 from 3420 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Moving on to step 9:
The number 350 fits into 2700 7 times, leaving a remainder of 250.
Put 7 as the next digit of the answer. 
Result so far: 137189.7
Subtract 2450 from 2700 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
When dividing 2500 by 350, we get 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 137189.77
Subtract 2450 from 2500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 137189.77, with a leftover of 0.05.
