We look at the division of 39054566 by 639 
We want to divide 39054566 by 639.

Advancing to step 1:
When dividing 3 by 639, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 639

Advancing to step 2:
39 divided by 639 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 639

Let's proceed to step 3:
When dividing 390 by 639, we get 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 390, we end up with 390.
Fetch the next digit (5) from the dividend, attach it to 390 and continue: 3905 / 639

Advancing to step 4:
If we divide 3905 by 639, we get 6 and a remainder of 71.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 71 after subtracting 3834 from 3905.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 639

Going ahead to step 5:
639 can be fit into 714 1 times, resulting in a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Deduct 639 from 714 and we're left with 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 639

Step 6:
639 can be fit into 755 1 times, resulting in a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 611.0
The remainder is 116 after subtracting 639 from 755.
Take the next digit (6) from the dividend and append it to 116, then repeat: 1166 / 639

Going ahead to step 7:
When dividing 1166 by 639, we get 1 with a remainder of 527.
Record the quotient 1 as the next digit in the result. 
Result so far: 6111.0
Subtracting 639 from 1166 leaves us with 527.
Bring next digit (6) of the dividend behind the 527 and repeat the process: 5276 / 639

Advancing to step 8:
The number 639 fits into 5276 8 times, leaving a remainder of 164.
The next digit of our result is 8. 
Result so far: 61118.0
Deduct 5112 from 5276 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 9:
The number 639 fits into 1640 2 times, leaving a remainder of 362.
Record the quotient 2 as the next digit in the result. 
Result so far: 61118.2
If we subtract 1278 from 1640, we get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 10:
639 goes into 3620 5 times with a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 61118.25
Subtract 3195 from 3620 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 11:
639 can be fit into 4250 6 times, resulting in a remainder of 416.
Put 6 as the next digit of the answer. 
Result so far: 61118.256
Deduct 3834 from 4250 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 12:
The number 639 fits into 4160 6 times, leaving a remainder of 326.
The number 6 becomes the next digit in our result. 
Result so far: 61118.2566
If we take 3834 away from 4160, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Our division results in 61118.2566 with a remaining 0.00326.
