We divide 54386391 by 425
Our goal is to divide 54386391 by 425.

Let's proceed to step 1:
425 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 425

Moving on to step 2:
When dividing 54 by 425, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 425

Going ahead to step 3:
425 goes into 543 1 times with a remainder of 118.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 425 from 543 leaves us with 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 425

Step 4:
1188 divided by 425 is 2 with a remainder of 338.
The next digit of our result is 2. 
Result so far: 12.0
If we take 850 away from 1188, we end up with 338.
Append the next digit (6) from the dividend to 338 and continue with: 3386 / 425

Moving on to step 5:
If we divide 3386 by 425, we get 7 and a remainder of 411.
Put 7 as the next digit of the answer. 
Result so far: 127.0
If we subtract 2975 from 3386, we get 411.
Include the next digit (3) from the dividend after 411, then repeat: 4113 / 425

Going ahead to step 6:
The number 425 fits into 4113 9 times, leaving a remainder of 288.
Write down 9 as next digit of the result. 
Result so far: 1279.0
Subtract 3825 from 4113 to get 288.
Take the next digit (9) from the dividend and append it to 288, then repeat: 2889 / 425

On to step 7:
The number 425 fits into 2889 6 times, leaving a remainder of 339.
Put 6 as the next digit of the answer. 
Result so far: 12796.0
Subtracting 2550 from 2889 leaves us with 339.
Grab the next digit (1) from the dividend, add it to 339, then carry on: 3391 / 425

Going ahead to step 8:
3391 divided by 425 is 7 with a remainder of 416.
Use 7 as the next digit of our solution. 
Result so far: 127967.0
Subtracting 2975 from 3391 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 9:
4160 divided by 425 is 9 with a remainder of 335.
Put 9 as the next digit of the answer. 
Result so far: 127967.9
If we subtract 3825 from 4160, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 10:
425 can be fit into 3350 7 times, resulting in a remainder of 375.
Put 7 as the next digit of the answer. 
Result so far: 127967.97
If we take 2975 away from 3350, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 11:
425 can be fit into 3750 8 times, resulting in a remainder of 350.
Use 8 as the next digit of our solution. 
Result so far: 127967.978
Deduct 3400 from 3750 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 12:
425 can be fit into 3500 8 times, resulting in a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 127967.9788
Subtract 3400 from 3500 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.

In conclusion, the division gives 127967.9788 with a balance of 0.001.
