20886218 divided by 425 
The aim is to understand the frequency of 425 in 20886218.

On to step 1:
2 divided by 425 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 425

Let's proceed to step 2:
When dividing 20 by 425, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 425

Going ahead to step 3:
208 divided by 425 is 0 with a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Grab the next digit (8) from the dividend, add it to 208, then carry on: 2088 / 425

Step 4:
425 goes into 2088 4 times with a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1700 from 2088 to get 388.
Include the next digit (6) from the dividend after 388, then repeat: 3886 / 425

Going ahead to step 5:
The number 425 fits into 3886 9 times, leaving a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 3825 from 3886 to get 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 425

On to step 6:
612 divided by 425 is 1 with a remainder of 187.
The number 1 becomes the next digit in our result. 
Result so far: 491.0
Subtracting 425 from 612 leaves us with 187.
Bring next digit (1) of the dividend behind the 187 and repeat the process: 1871 / 425

Let's proceed to step 7:
When dividing 1871 by 425, we get 4 with a remainder of 171.
The next digit of our result is 4. 
Result so far: 4914.0
If we take 1700 away from 1871, we end up with 171.
Bring next digit (8) of the dividend behind the 171 and repeat the process: 1718 / 425

Moving on to step 8:
425 goes into 1718 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 49144.0
If we take 1700 away from 1718, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
425 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 49144.0
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 425, we get 4 with a remainder of 100.
The next digit of our result is 4. 
Result so far: 49144.04
Subtract 1700 from 1800 to 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.

Step 11:
If we divide 1000 by 425, we get 2 and a remainder of 150.
Put 2 as the next digit of the answer. 
Result so far: 49144.042
Subtract 850 from 1000 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
1500 divided by 425 is 3 with a remainder of 225.
Put 3 as the next digit of the answer. 
Result so far: 49144.0423
Subtracting 1275 from 1500 leaves us 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.

Advancing to step 13:
425 can be fit into 2250 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 49144.04235
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.

Let's proceed to step 14:
425 goes into 1250 2 times with a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 49144.042352
Subtracting 850 from 1250 leaves us 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.

Going ahead to step 15:
When dividing 4000 by 425, we get 9 with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 49144.0423529
If we take 3825 away from 4000, we end up 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.

Let's proceed to step 16:
425 can be fit into 1750 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 49144.04235294
Subtracting 1700 from 1750 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 49144.04235294 with a remaining 5e-08.
