15420630 ÷ 635 
We want to divide 15420630 by 635.

Moving on to step 1:
When dividing 1 by 635, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 635

Going ahead to step 2:
635 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 635

Let's proceed to step 3:
If we divide 154 by 635, we get 0 and a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Fetch the next digit (2) from the dividend, attach it to 154 and continue: 1542 / 635

Let's proceed to step 4:
635 can be fit into 1542 2 times, resulting in a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 272 after subtracting 1270 from 1542.
Grab the next digit (0) from the dividend, add it to 272, then carry on: 2720 / 635

Let's proceed to step 5:
If we divide 2720 by 635, we get 4 and a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 2540 away from 2720, we end up with 180.
Bring next digit (6) of the dividend behind the 180 and repeat the process: 1806 / 635

Let's proceed to step 6:
635 can be fit into 1806 2 times, resulting in a remainder of 536.
The number 2 becomes the next digit in our result. 
Result so far: 242.0
Subtract 1270 from 1806 to get 536.
Bring next digit (3) of the dividend behind the 536 and repeat the process: 5363 / 635

Advancing to step 7:
When dividing 5363 by 635, we get 8 with a remainder of 283.
The number 8 becomes the next digit in our result. 
Result so far: 2428.0
Deduct 5080 from 5363 and we're left with 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 635

On to step 8:
2830 divided by 635 is 4 with a remainder of 290.
The next digit of our result is 4. 
Result so far: 24284.0
The remainder is 290 after subtracting 2540 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 9:
The number 635 fits into 2900 4 times, leaving a remainder of 360.
Put 4 as the next digit of the answer. 
Result so far: 24284.4
If we subtract 2540 from 2900, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
If we divide 3600 by 635, we get 5 and a remainder of 425.
The next digit of our result is 5. 
Result so far: 24284.45
If we take 3175 away from 3600, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 11:
The number 635 fits into 4250 6 times, leaving a remainder of 440.
Use 6 as the next digit of our solution. 
Result so far: 24284.456
The remainder is 440 after subtracting 3810 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
635 goes into 4400 6 times with a remainder of 590.
Put 6 as the next digit of the answer. 
Result so far: 24284.4566
Deduct 3810 from 4400 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final result is 24284.4566 with a remainder of 0.0059.
