397912 divided by 54 
We're looking to find how many times 54 goes into 397912.

Step 1:
3 divided by 54 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 54

Going ahead to step 2:
The number 54 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 54

Let's proceed to step 3:
The number 54 fits into 397 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 378 from 397, we get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 54

On to step 4:
When dividing 199 by 54, we get 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 162 from 199 and we're left with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 54

Moving on to step 5:
If we divide 371 by 54, we get 6 and a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 736.0
Subtracting 324 from 371 leaves us with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 54

Step 6:
If we divide 472 by 54, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 7368.0
The remainder is 40 after subtracting 432 from 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
400 divided by 54 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7368.7
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
The number 54 fits into 220 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 7368.74
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7368.74
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 54, we get 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7368.7407
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
220 divided by 54 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 7368.74074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 54, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7368.74074
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 54 fits into 400 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 7368.7407407
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
54 goes into 220 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 7368.74074074
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 7368.74074074 with a remaining 4e-09.
