423372 divided by 54 
We're looking to find how many times 54 goes into 423372.

On to step 1:
54 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 54

On to step 2:
The number 54 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 54

Moving on to step 3:
54 can be fit into 423 7 times, resulting in a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 378 from 423 leaves us with 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 54

Advancing to step 4:
The number 54 fits into 453 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
If we take 432 away from 453, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 54

Step 5:
54 goes into 217 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 784.0
Subtract 216 from 217 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 54

Advancing to step 6:
If we divide 12 by 54, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 7840.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 54 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 7840.2
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 54, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 7840.22
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 7840.22 with a remainder of 0.012.
