30635113 ÷ 639 
Our goal is to divide 30635113 by 639.

Step 1:
If we divide 3 by 639, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 639

Let's proceed to step 2:
639 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 639

Advancing to step 3:
If we divide 306 by 639, we get 0 and a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 306 and we're left with 306.
Grab the next digit (3) from the dividend, add it to 306, then carry on: 3063 / 639

On to step 4:
When dividing 3063 by 639, we get 4 with a remainder of 507.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 507 after subtracting 2556 from 3063.
Append the next digit (5) from the dividend to 507 and continue with: 5075 / 639

Let's proceed to step 5:
639 can be fit into 5075 7 times, resulting in a remainder of 602.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Deduct 4473 from 5075 and we're left with 602.
Fetch the next digit (1) from the dividend, attach it to 602 and continue: 6021 / 639

Step 6:
639 can be fit into 6021 9 times, resulting in a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 479.0
Subtract 5751 from 6021 to get 270.
Append the next digit (1) from the dividend to 270 and continue with: 2701 / 639

On to step 7:
639 can be fit into 2701 4 times, resulting in a remainder of 145.
The next digit of our result is 4. 
Result so far: 4794.0
If we subtract 2556 from 2701, we get 145.
Grab the next digit (3) from the dividend, add it to 145, then carry on: 1453 / 639

Advancing to step 8:
1453 divided by 639 is 2 with a remainder of 175.
Record the quotient 2 as the next digit in the result. 
Result so far: 47942.0
If we take 1278 away from 1453, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 9:
639 can be fit into 1750 2 times, resulting in a remainder of 472.
The next digit of our result is 2. 
Result so far: 47942.2
The remainder is 472 after subtracting 1278 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 10:
639 goes into 4720 7 times with a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 47942.27
Subtracting 4473 from 4720 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 11:
639 goes into 2470 3 times with a remainder of 553.
The number 3 becomes the next digit in our result. 
Result so far: 47942.273
Subtract 1917 from 2470 to get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 12:
5530 divided by 639 is 8 with a remainder of 418.
Write down 8 as next digit of the result. 
Result so far: 47942.2738
Subtract 5112 from 5530 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 13:
4180 divided by 639 is 6 with a remainder of 346.
The next digit of our result is 6. 
Result so far: 47942.27386
If we subtract 3834 from 4180, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

On to step 14:
3460 divided by 639 is 5 with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 47942.273865
Deduct 3195 from 3460 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 15:
639 goes into 2650 4 times with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 47942.2738654
Subtracting 2556 from 2650 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 16:
940 divided by 639 is 1 with a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 47942.27386541
If we take 639 away from 940, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final result is 47942.27386541 with a remainder of 3.01e-07.
