We look at the division of 39949828 by 425 
The aim is to understand the frequency of 425 in 39949828.

Let's proceed to step 1:
425 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 425

Let's proceed to step 2:
When dividing 39 by 425, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 425

Advancing to step 3:
399 divided by 425 is 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Append the next digit (4) from the dividend to 399 and continue with: 3994 / 425

Going ahead to step 4:
425 goes into 3994 9 times with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 3825 from 3994 to get 169.
Fetch the next digit (9) from the dividend, attach it to 169 and continue: 1699 / 425

Step 5:
The number 425 fits into 1699 3 times, leaving a remainder of 424.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 1275 from 1699 and we're left with 424.
Append the next digit (8) from the dividend to 424 and continue with: 4248 / 425

Let's proceed to step 6:
425 goes into 4248 9 times with a remainder of 423.
Use 9 as the next digit of our solution. 
Result so far: 939.0
The remainder is 423 after subtracting 3825 from 4248.
Bring next digit (2) of the dividend behind the 423 and repeat the process: 4232 / 425

Let's proceed to step 7:
The number 425 fits into 4232 9 times, leaving a remainder of 407.
Use 9 as the next digit of our solution. 
Result so far: 9399.0
The remainder is 407 after subtracting 3825 from 4232.
Fetch the next digit (8) from the dividend, attach it to 407 and continue: 4078 / 425

Moving on to step 8:
If we divide 4078 by 425, we get 9 and a remainder of 253.
Use 9 as the next digit of our solution. 
Result so far: 93999.0
If we subtract 3825 from 4078, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 9:
425 goes into 2530 5 times with a remainder of 405.
The next digit of our result is 5. 
Result so far: 93999.5
The remainder is 405 after subtracting 2125 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 10:
If we divide 4050 by 425, we get 9 and a remainder of 225.
Use 9 as the next digit of our solution. 
Result so far: 93999.59
If we subtract 3825 from 4050, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 11:
The number 425 fits into 2250 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 93999.595
Subtracting 2125 from 2250 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
425 can be fit into 1250 2 times, resulting in a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 93999.5952
Deduct 850 from 1250 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
425 can be fit into 4000 9 times, resulting in a remainder of 175.
Use 9 as the next digit of our solution. 
Result so far: 93999.59529
Subtracting 3825 from 4000 leaves us with 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 14:
If we divide 1750 by 425, we get 4 and a remainder of 50.
The next digit of our result is 4. 
Result so far: 93999.595294
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.

Going ahead to step 15:
425 goes into 500 1 times with a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 93999.5952941
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.

On to step 16:
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: 93999.59529411
Subtracting 425 from 750 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 93999.59529411 and a remainder of 3.25e-07.
