Let's divide 42389 by 54
We want to divide 42389 by 54.

On to step 1:
54 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 54

Moving on to step 2:
54 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 54

Step 3:
If we divide 423 by 54, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 378 from 423 leaves us with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 54

Going ahead to step 4:
54 can be fit into 458 8 times, resulting in a remainder of 26.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 26 after subtracting 432 from 458.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 54

Step 5:
54 can be fit into 269 4 times, resulting in a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 784.0
Subtract 216 from 269 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 6:
54 can be fit into 530 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 784.9
Subtracting 486 from 530 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
If we divide 440 by 54, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 784.98
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 784.981
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
The number 54 fits into 260 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 784.9814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
440 divided by 54 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 784.98148
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
54 can be fit into 80 1 times, resulting in a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 784.981481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
54 can be fit into 260 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 784.9814814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
440 divided by 54 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 784.98148148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 784.98148148 and a remainder of 8e-09.
