423139 divided by 54 
We want to divide 423139 by 54.

Moving on to step 1:
54 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 54

On to step 2:
54 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 54

Let's proceed to step 3:
If we divide 423 by 54, we get 7 and a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 378 from 423 and we're left with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 54

Going ahead to step 4:
54 goes into 451 8 times with a remainder of 19.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 432 from 451 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 54

On to step 5:
The number 54 fits into 193 3 times, leaving a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 783.0
Subtract 162 from 193 to get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 54

On to step 6:
If we divide 319 by 54, we get 5 and a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 7835.0
If we take 270 away from 319, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
The number 54 fits into 490 9 times, leaving a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 7835.9
If we subtract 486 from 490, we 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.

Going ahead to step 8:
When dividing 40 by 54, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7835.9
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.

Going ahead to step 9:
54 goes into 400 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 7835.907
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.

Let's proceed to step 10:
The number 54 fits into 220 4 times, leaving a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 7835.9074
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 54 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7835.9074
If we subtract 0 from 40, we 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.

Moving on to step 12:
400 divided by 54 is 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 7835.907407
If we take 378 away from 400, we end up 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.

Advancing to step 13:
The number 54 fits into 220 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 7835.9074074
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.

Going ahead to step 14:
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: 7835.9074074
If we take 0 away from 40, we end up 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.

After the division, we end up with 7835.9074074 and a remainder of 4e-08.
