We look at the division of 70142856 by 425 
The aim is to understand the frequency of 425 in 70142856.

Advancing to step 1:
425 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 425

Advancing to step 2:
425 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (1) from the dividend, attach it to 70 and continue: 701 / 425

Let's proceed to step 3:
The number 425 fits into 701 1 times, leaving a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 425 from 701 and we're left with 276.
Fetch the next digit (4) from the dividend, attach it to 276 and continue: 2764 / 425

Step 4:
When dividing 2764 by 425, we get 6 with a remainder of 214.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 2550 away from 2764, we end up with 214.
Bring next digit (2) of the dividend behind the 214 and repeat the process: 2142 / 425

Step 5:
2142 divided by 425 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Subtracting 2125 from 2142 leaves us with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 425

Step 6:
The number 425 fits into 178 0 times, leaving a remainder of 178.
Record the quotient 0 as the next digit in the result. 
Result so far: 1650.0
If we take 0 away from 178, we end up with 178.
Grab the next digit (5) from the dividend, add it to 178, then carry on: 1785 / 425

Step 7:
If we divide 1785 by 425, we get 4 and a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 16504.0
Subtract 1700 from 1785 to get 85.
Take the next digit (6) from the dividend and append it to 85, then repeat: 856 / 425

Moving on to step 8:
425 goes into 856 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 165042.0
The remainder is 6 after subtracting 850 from 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
When dividing 60 by 425, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 165042.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
The number 425 fits into 600 1 times, leaving a remainder of 175.
The next digit of our result is 1. 
Result so far: 165042.01
If we subtract 425 from 600, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
If we divide 1750 by 425, we get 4 and a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 165042.014
Subtract 1700 from 1750 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.

Advancing to step 12:
425 goes into 500 1 times with a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 165042.0141
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
The number 425 fits into 750 1 times, leaving a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 165042.01411
If we subtract 425 from 750, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Our division results in 165042.01411 with a remaining 0.000325.
