45390865 divided by 425 
The aim is to understand the frequency of 425 in 45390865.

Step 1:
4 divided by 425 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 425

Let's proceed to step 2:
425 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 425

On to step 3:
425 goes into 453 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 425 from 453, we get 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 425

Let's proceed to step 4:
289 divided by 425 is 0 with a remainder of 289.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 289 after subtracting 0 from 289.
Include the next digit (0) from the dividend after 289, then repeat: 2890 / 425

On to step 5:
The number 425 fits into 2890 6 times, leaving a remainder of 340.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we take 2550 away from 2890, we end up with 340.
Append the next digit (8) from the dividend to 340 and continue with: 3408 / 425

Advancing to step 6:
When dividing 3408 by 425, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 1068.0
If we subtract 3400 from 3408, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 425

Going ahead to step 7:
When dividing 86 by 425, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 10680.0
If we take 0 away from 86, we end up with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 425

Going ahead to step 8:
425 can be fit into 865 2 times, resulting in a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 106802.0
Deduct 850 from 865 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 425, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 106802.0
If we take 0 away from 150, we end up 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.

Advancing to step 10:
If we divide 1500 by 425, we get 3 and a remainder of 225.
The number 3 becomes the next digit in our result. 
Result so far: 106802.03
If we take 1275 away from 1500, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
425 goes into 2250 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 106802.035
Deduct 2125 from 2250 and we're left 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.

Step 12:
When dividing 1250 by 425, we get 2 with a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 106802.0352
Subtract 850 from 1250 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
425 goes into 4000 9 times with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 106802.03529
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.

Step 14:
425 goes into 1750 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 106802.035294
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 15:
500 divided by 425 is 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 106802.0352941
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 16:
425 can be fit into 750 1 times, resulting in a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 106802.03529411
Subtract 425 from 750 to 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.

The final result is 106802.03529411 with a remainder of 3.25e-07.
