8729349 ÷ 642 
We're looking to find how many times 642 goes into 8729349.

Going ahead to step 1:
8 divided by 642 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 642

On to step 2:
If we divide 87 by 642, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Include the next digit (2) from the dividend after 87, then repeat: 872 / 642

Let's proceed to step 3:
If we divide 872 by 642, we get 1 and a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 642 from 872 leaves us with 230.
Take the next digit (9) from the dividend and append it to 230, then repeat: 2309 / 642

On to step 4:
The number 642 fits into 2309 3 times, leaving a remainder of 383.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1926 from 2309 and we're left with 383.
Append the next digit (3) from the dividend to 383 and continue with: 3833 / 642

On to step 5:
When dividing 3833 by 642, we get 5 with a remainder of 623.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Deduct 3210 from 3833 and we're left with 623.
Fetch the next digit (4) from the dividend, attach it to 623 and continue: 6234 / 642

Moving on to step 6:
642 can be fit into 6234 9 times, resulting in a remainder of 456.
The next digit of our result is 9. 
Result so far: 1359.0
If we subtract 5778 from 6234, we get 456.
Append the next digit (9) from the dividend to 456 and continue with: 4569 / 642

On to step 7:
If we divide 4569 by 642, we get 7 and a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 13597.0
If we take 4494 away from 4569, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
642 can be fit into 750 1 times, resulting in a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 13597.1
Subtracting 642 from 750 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
1080 divided by 642 is 1 with a remainder of 438.
Write down 1 as next digit of the result. 
Result so far: 13597.11
If we take 642 away from 1080, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The quotient of the division is 13597.11, and the remainder is 0.438.
