We look at the division of 422187 by 54 
We want to figure out the number of times 422187 can be divided by 54.

On to step 1:
54 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 54

On to step 2:
If we divide 42 by 54, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 54

On to step 3:
When dividing 422 by 54, we get 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 44 after subtracting 378 from 422.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 54

Going ahead to step 4:
54 goes into 441 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 432 from 441 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 54

Let's proceed to step 5:
If we divide 98 by 54, we get 1 and a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 781.0
The remainder is 44 after subtracting 54 from 98.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 54

Let's proceed to step 6:
447 divided by 54 is 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 7818.0
If we take 432 away from 447, we end up 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.

Moving on to step 7:
When dividing 150 by 54, we get 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 7818.2
Subtracting 108 from 150 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
420 divided by 54 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 7818.27
Subtracting 378 from 420 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 9:
When dividing 420 by 54, we get 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 7818.277
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 7818.277 with a remaining 0.0042.
