We divide 50485571 by 350
The aim is to understand the frequency of 350 in 50485571.

Advancing to step 1:
If we divide 5 by 350, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 350

Advancing to step 2:
350 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 350

Moving on to step 3:
350 can be fit into 504 1 times, resulting in a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 154 after subtracting 350 from 504.
Grab the next digit (8) from the dividend, add it to 154, then carry on: 1548 / 350

Going ahead to step 4:
350 goes into 1548 4 times with a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1400 from 1548, we get 148.
Bring next digit (5) of the dividend behind the 148 and repeat the process: 1485 / 350

Going ahead to step 5:
350 goes into 1485 4 times with a remainder of 85.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Deduct 1400 from 1485 and we're left with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 350

Going ahead to step 6:
350 can be fit into 855 2 times, resulting in a remainder of 155.
Put 2 as the next digit of the answer. 
Result so far: 1442.0
The remainder is 155 after subtracting 700 from 855.
Grab the next digit (7) from the dividend, add it to 155, then carry on: 1557 / 350

Moving on to step 7:
If we divide 1557 by 350, we get 4 and a remainder of 157.
Write down 4 as next digit of the result. 
Result so far: 14424.0
The remainder is 157 after subtracting 1400 from 1557.
Take the next digit (1) from the dividend and append it to 157, then repeat: 1571 / 350

Step 8:
350 can be fit into 1571 4 times, resulting in a remainder of 171.
Put 4 as the next digit of the answer. 
Result so far: 144244.0
The remainder is 171 after subtracting 1400 from 1571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 9:
350 goes into 1710 4 times with a remainder of 310.
The number 4 becomes the next digit in our result. 
Result so far: 144244.4
If we subtract 1400 from 1710, we 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 10:
When dividing 3100 by 350, we get 8 with a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 144244.48
Subtracting 2800 from 3100 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
3000 divided by 350 is 8 with a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 144244.488
If we subtract 2800 from 3000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 144244.488 with a remainder of 0.02.
