15319124 ÷ 642 
We want to divide 15319124 by 642.

Moving on to step 1:
If we divide 1 by 642, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 642

Step 2:
15 divided by 642 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 642

Step 3:
If we divide 153 by 642, we get 0 and a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 153 after subtracting 0 from 153.
Include the next digit (1) from the dividend after 153, then repeat: 1531 / 642

Advancing to step 4:
When dividing 1531 by 642, we get 2 with a remainder of 247.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 247 after subtracting 1284 from 1531.
Take the next digit (9) from the dividend and append it to 247, then repeat: 2479 / 642

Let's proceed to step 5:
The number 642 fits into 2479 3 times, leaving a remainder of 553.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 1926 from 2479, we get 553.
Include the next digit (1) from the dividend after 553, then repeat: 5531 / 642

Advancing to step 6:
642 goes into 5531 8 times with a remainder of 395.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
If we subtract 5136 from 5531, we get 395.
Fetch the next digit (2) from the dividend, attach it to 395 and continue: 3952 / 642

Moving on to step 7:
642 goes into 3952 6 times with a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 2386.0
If we take 3852 away from 3952, we end up with 100.
Append the next digit (4) from the dividend to 100 and continue with: 1004 / 642

Advancing to step 8:
When dividing 1004 by 642, we get 1 with a remainder of 362.
Put 1 as the next digit of the answer. 
Result so far: 23861.0
Subtract 642 from 1004 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 9:
The number 642 fits into 3620 5 times, leaving a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 23861.5
If we subtract 3210 from 3620, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
When dividing 4100 by 642, we get 6 with a remainder of 248.
The number 6 becomes the next digit in our result. 
Result so far: 23861.56
Subtract 3852 from 4100 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
2480 divided by 642 is 3 with a remainder of 554.
Record the quotient 3 as the next digit in the result. 
Result so far: 23861.563
Deduct 1926 from 2480 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 12:
642 can be fit into 5540 8 times, resulting in a remainder of 404.
Use 8 as the next digit of our solution. 
Result so far: 23861.5638
If we subtract 5136 from 5540, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 13:
If we divide 4040 by 642, we get 6 and a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 23861.56386
Deduct 3852 from 4040 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 14:
1880 divided by 642 is 2 with a remainder of 596.
Use 2 as the next digit of our solution. 
Result so far: 23861.563862
The remainder is 596 after subtracting 1284 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 15:
5960 divided by 642 is 9 with a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 23861.5638629
Subtracting 5778 from 5960 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 16:
642 can be fit into 1820 2 times, resulting in a remainder of 536.
The next digit of our result is 2. 
Result so far: 23861.56386292
Deduct 1284 from 1820 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

After the division, we end up with 23861.56386292 and a remainder of 5.36e-07.
