54388910 ÷ 350 
The aim is to understand the frequency of 350 in 54388910.

Advancing to step 1:
5 divided by 350 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 350

On to step 2:
350 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 350

Step 3:
350 can be fit into 543 1 times, resulting in a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 350 from 543 leaves us with 193.
Grab the next digit (8) from the dividend, add it to 193, then carry on: 1938 / 350

Let's proceed to step 4:
1938 divided by 350 is 5 with a remainder of 188.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 1750 away from 1938, we end up with 188.
Include the next digit (8) from the dividend after 188, then repeat: 1888 / 350

Moving on to step 5:
350 can be fit into 1888 5 times, resulting in a remainder of 138.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 138 after subtracting 1750 from 1888.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 350

Let's proceed to step 6:
If we divide 1389 by 350, we get 3 and a remainder of 339.
Write down 3 as next digit of the result. 
Result so far: 1553.0
Subtracting 1050 from 1389 leaves us with 339.
Include the next digit (1) from the dividend after 339, then repeat: 3391 / 350

Let's proceed to step 7:
3391 divided by 350 is 9 with a remainder of 241.
The next digit of our result is 9. 
Result so far: 15539.0
The remainder is 241 after subtracting 3150 from 3391.
Grab the next digit (0) from the dividend, add it to 241, then carry on: 2410 / 350

On to step 8:
2410 divided by 350 is 6 with a remainder of 310.
The next digit of our result is 6. 
Result so far: 155396.0
Subtract 2100 from 2410 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 9:
When dividing 3100 by 350, we get 8 with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 155396.8
If we subtract 2800 from 3100, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
The number 350 fits into 3000 8 times, leaving a remainder of 200.
Put 8 as the next digit of the answer. 
Result so far: 155396.88
The remainder is 200 after subtracting 2800 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 155396.88 with a balance of 0.2.
