We look at the division of 28923953 by 639 
We want to divide 28923953 by 639.

Let's proceed to step 1:
The number 639 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 639

Moving on to step 2:
When dividing 28 by 639, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 639

On to step 3:
639 can be fit into 289 0 times, resulting in a remainder of 289.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 289 to get 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 639

On to step 4:
The number 639 fits into 2892 4 times, leaving a remainder of 336.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2556 from 2892, we get 336.
Take the next digit (3) from the dividend and append it to 336, then repeat: 3363 / 639

Moving on to step 5:
639 goes into 3363 5 times with a remainder of 168.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 3195 from 3363 and we're left with 168.
Append the next digit (9) from the dividend to 168 and continue with: 1689 / 639

Let's proceed to step 6:
639 can be fit into 1689 2 times, resulting in a remainder of 411.
Put 2 as the next digit of the answer. 
Result so far: 452.0
If we take 1278 away from 1689, we end up with 411.
Grab the next digit (5) from the dividend, add it to 411, then carry on: 4115 / 639

On to step 7:
639 goes into 4115 6 times with a remainder of 281.
Put 6 as the next digit of the answer. 
Result so far: 4526.0
Subtract 3834 from 4115 to get 281.
Fetch the next digit (3) from the dividend, attach it to 281 and continue: 2813 / 639

Advancing to step 8:
If we divide 2813 by 639, we get 4 and a remainder of 257.
The next digit of our result is 4. 
Result so far: 45264.0
If we take 2556 away from 2813, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 9:
2570 divided by 639 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 45264.4
Deduct 2556 from 2570 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
If we divide 140 by 639, we get 0 and a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 45264.4
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 639, we get 2 with a remainder of 122.
Use 2 as the next digit of our solution. 
Result so far: 45264.402
Deduct 1278 from 1400 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 12:
639 can be fit into 1220 1 times, resulting in a remainder of 581.
Use 1 as the next digit of our solution. 
Result so far: 45264.4021
Subtract 639 from 1220 to get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 13:
When dividing 5810 by 639, we get 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 45264.40219
Deduct 5751 from 5810 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
639 can be fit into 590 0 times, resulting in a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 45264.40219
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 15:
When dividing 5900 by 639, we get 9 with a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 45264.4021909
Subtract 5751 from 5900 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Let's proceed to step 16:
The number 639 fits into 1490 2 times, leaving a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 45264.40219092
Subtract 1278 from 1490 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

After the division, we end up with 45264.40219092 and a remainder of 2.12e-07.
