We look at the division of 639040 by 54 
We want to divide 639040 by 54.

Going ahead to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 54

Advancing to step 2:
If we divide 63 by 54, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 54 from 63 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 54

Let's proceed to step 3:
99 divided by 54 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 11.0
If we take 54 away from 99, we end up with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 54

Let's proceed to step 4:
54 can be fit into 450 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we subtract 432 from 450, we get 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 54

On to step 5:
54 goes into 184 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 1183.0
Subtract 162 from 184 to get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 54

Moving on to step 6:
54 can be fit into 220 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 11834.0
Deduct 216 from 220 and we're left 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.

Moving on to step 7:
If we divide 40 by 54, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11834.0
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.

Going ahead to step 8:
If we divide 400 by 54, we get 7 and a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 11834.07
Subtract 378 from 400 to 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.

On to step 9:
When dividing 220 by 54, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 11834.074
The remainder is 4 after subtracting 216 from 220.
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 10:
When dividing 40 by 54, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11834.074
The remainder is 40 after subtracting 0 from 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 11:
The number 54 fits into 400 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 11834.07407
Deduct 378 from 400 and we're left 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 12:
If we divide 220 by 54, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 11834.074074
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 54 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 11834.074074
The remainder is 40 after subtracting 0 from 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 14:
If we divide 400 by 54, we get 7 and a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 11834.07407407
Subtract 378 from 400 to 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.

After the division, we end up with 11834.07407407 and a remainder of 2.2e-08.
