We're dividing 1984924 by 639 
Our goal is to divide 1984924 by 639.

Going ahead to step 1:
639 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 639

Step 2:
If we divide 19 by 639, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 639

Advancing to step 3:
The number 639 fits into 198 0 times, leaving a remainder of 198.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Fetch the next digit (4) from the dividend, attach it to 198 and continue: 1984 / 639

Let's proceed to step 4:
When dividing 1984 by 639, we get 3 with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1917 away from 1984, we end up with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 639

On to step 5:
679 divided by 639 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 639 from 679 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 639

Step 6:
639 can be fit into 402 0 times, resulting in a remainder of 402.
The next digit of our result is 0. 
Result so far: 310.0
Subtracting 0 from 402 leaves us with 402.
Fetch the next digit (4) from the dividend, attach it to 402 and continue: 4024 / 639

Advancing to step 7:
639 can be fit into 4024 6 times, resulting in a remainder of 190.
The next digit of our result is 6. 
Result so far: 3106.0
If we subtract 3834 from 4024, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 8:
When dividing 1900 by 639, we get 2 with a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 3106.2
Subtracting 1278 from 1900 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

On to step 9:
639 can be fit into 6220 9 times, resulting in a remainder of 469.
Put 9 as the next digit of the answer. 
Result so far: 3106.29
If we subtract 5751 from 6220, we get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Going ahead to step 10:
The number 639 fits into 4690 7 times, leaving a remainder of 217.
Write down 7 as next digit of the result. 
Result so far: 3106.297
If we subtract 4473 from 4690, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 11:
When dividing 2170 by 639, we get 3 with a remainder of 253.
The next digit of our result is 3. 
Result so far: 3106.2973
Deduct 1917 from 2170 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 12:
2530 divided by 639 is 3 with a remainder of 613.
Write down 3 as next digit of the result. 
Result so far: 3106.29733
Subtract 1917 from 2530 to get 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

After the division, we end up with 3106.29733 and a remainder of 0.000613.
