We look at the division of 14288325 by 850 
The aim is to understand the frequency of 850 in 14288325.

Step 1:
850 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 850

Moving on to step 2:
If we divide 14 by 850, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 850

Step 3:
If we divide 142 by 850, we get 0 and a remainder of 142.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 142, we end up with 142.
Grab the next digit (8) from the dividend, add it to 142, then carry on: 1428 / 850

Step 4:
850 can be fit into 1428 1 times, resulting in a remainder of 578.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 850 from 1428, we get 578.
Bring next digit (8) of the dividend behind the 578 and repeat the process: 5788 / 850

Going ahead to step 5:
If we divide 5788 by 850, we get 6 and a remainder of 688.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 5100 from 5788, we get 688.
Include the next digit (3) from the dividend after 688, then repeat: 6883 / 850

Moving on to step 6:
If we divide 6883 by 850, we get 8 and a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Deduct 6800 from 6883 and we're left with 83.
Fetch the next digit (2) from the dividend, attach it to 83 and continue: 832 / 850

Advancing to step 7:
If we divide 832 by 850, we get 0 and a remainder of 832.
Put 0 as the next digit of the answer. 
Result so far: 1680.0
Deduct 0 from 832 and we're left with 832.
Bring next digit (5) of the dividend behind the 832 and repeat the process: 8325 / 850

Advancing to step 8:
The number 850 fits into 8325 9 times, leaving a remainder of 675.
Use 9 as the next digit of our solution. 
Result so far: 16809.0
If we subtract 7650 from 8325, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 9:
The number 850 fits into 6750 7 times, leaving a remainder of 800.
Put 7 as the next digit of the answer. 
Result so far: 16809.7
Subtracting 5950 from 6750 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 10:
850 can be fit into 8000 9 times, resulting in a remainder of 350.
Write down 9 as next digit of the result. 
Result so far: 16809.79
If we take 7650 away from 8000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
The number 850 fits into 3500 4 times, leaving a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 16809.794
If we subtract 3400 from 3500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
If we divide 1000 by 850, we get 1 and a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 16809.7941
Subtracting 850 from 1000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
When dividing 1500 by 850, we get 1 with a remainder of 650.
The next digit of our result is 1. 
Result so far: 16809.79411
Subtracting 850 from 1500 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The quotient of the division is 16809.79411, and the remainder is 0.00065.
