We look at the division of 639080 by 46 
We want to divide 639080 by 46.

Step 1:
46 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 46

Going ahead to step 2:
46 goes into 63 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 46 from 63 and we're left with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 46

Going ahead to step 3:
46 goes into 179 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 138 from 179 to get 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 46

Advancing to step 4:
410 divided by 46 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 138.0
The remainder is 42 after subtracting 368 from 410.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 46

Let's proceed to step 5:
46 goes into 428 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 1389.0
Subtract 414 from 428 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 46

Going ahead to step 6:
The number 46 fits into 140 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 13893.0
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 46, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 13893.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 46 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 13893.04
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
46 can be fit into 160 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 13893.043
The remainder is 22 after subtracting 138 from 160.
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 10:
220 divided by 46 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 13893.0434
If we subtract 184 from 220, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
When dividing 360 by 46, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 13893.04347
Subtract 322 from 360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 46 fits into 380 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13893.043478
Deduct 368 from 380 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
46 can be fit into 120 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 13893.0434782
Deduct 92 from 120 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
The number 46 fits into 280 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13893.04347826
The remainder is 4 after subtracting 276 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 13893.04347826 with a remainder of 4e-09.
