Let's divide 18664185 by 425
We want to figure out the number of times 18664185 can be divided by 425.

Step 1:
425 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 425

Advancing to step 2:
425 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 425

Going ahead to step 3:
The number 425 fits into 186 0 times, leaving a remainder of 186.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 186, we get 186.
Bring next digit (6) of the dividend behind the 186 and repeat the process: 1866 / 425

Let's proceed to step 4:
1866 divided by 425 is 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 1700 from 1866 leaves us with 166.
Append the next digit (4) from the dividend to 166 and continue with: 1664 / 425

Moving on to step 5:
If we divide 1664 by 425, we get 3 and a remainder of 389.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 1275 away from 1664, we end up with 389.
Grab the next digit (1) from the dividend, add it to 389, then carry on: 3891 / 425

Going ahead to step 6:
3891 divided by 425 is 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 439.0
Deduct 3825 from 3891 and we're left with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 425

Step 7:
When dividing 668 by 425, we get 1 with a remainder of 243.
Use 1 as the next digit of our solution. 
Result so far: 4391.0
Subtracting 425 from 668 leaves us with 243.
Include the next digit (5) from the dividend after 243, then repeat: 2435 / 425

Advancing to step 8:
The number 425 fits into 2435 5 times, leaving a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 43915.0
If we subtract 2125 from 2435, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 9:
The number 425 fits into 3100 7 times, leaving a remainder of 125.
The next digit of our result is 7. 
Result so far: 43915.7
If we subtract 2975 from 3100, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
If we divide 1250 by 425, we get 2 and a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 43915.72
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.

On to step 11:
When dividing 4000 by 425, we get 9 with a remainder of 175.
Record the quotient 9 as the next digit in the result. 
Result so far: 43915.729
If we subtract 3825 from 4000, 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.

Moving on to step 12:
If we divide 1750 by 425, we get 4 and a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 43915.7294
If we take 1700 away from 1750, we end up 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.

Let's proceed to step 13:
425 can be fit into 500 1 times, resulting in a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 43915.72941
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.

On to step 14:
If we divide 750 by 425, we get 1 and a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 43915.729411
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.

The final outcome is 43915.729411, with a leftover of 3.25e-05.
