82739950 ÷ 642 
Let's see how many times 642 fits into 82739950.

Moving on to step 1:
The number 642 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 642

Step 2:
642 can be fit into 82 0 times, resulting in a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 642

On to step 3:
The number 642 fits into 827 1 times, leaving a remainder of 185.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 642 from 827 and we're left with 185.
Fetch the next digit (3) from the dividend, attach it to 185 and continue: 1853 / 642

Moving on to step 4:
The number 642 fits into 1853 2 times, leaving a remainder of 569.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1284 from 1853, we get 569.
Bring next digit (9) of the dividend behind the 569 and repeat the process: 5699 / 642

Let's proceed to step 5:
When dividing 5699 by 642, we get 8 with a remainder of 563.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtract 5136 from 5699 to get 563.
Fetch the next digit (9) from the dividend, attach it to 563 and continue: 5639 / 642

On to step 6:
642 can be fit into 5639 8 times, resulting in a remainder of 503.
Put 8 as the next digit of the answer. 
Result so far: 1288.0
Subtracting 5136 from 5639 leaves us with 503.
Bring next digit (5) of the dividend behind the 503 and repeat the process: 5035 / 642

Step 7:
When dividing 5035 by 642, we get 7 with a remainder of 541.
Put 7 as the next digit of the answer. 
Result so far: 12887.0
If we take 4494 away from 5035, we end up with 541.
Include the next digit (0) from the dividend after 541, then repeat: 5410 / 642

Going ahead to step 8:
5410 divided by 642 is 8 with a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 128878.0
The remainder is 274 after subtracting 5136 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 9:
2740 divided by 642 is 4 with a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 128878.4
The remainder is 172 after subtracting 2568 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
The number 642 fits into 1720 2 times, leaving a remainder of 436.
The number 2 becomes the next digit in our result. 
Result so far: 128878.42
If we subtract 1284 from 1720, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 11:
If we divide 4360 by 642, we get 6 and a remainder of 508.
The next digit of our result is 6. 
Result so far: 128878.426
Deduct 3852 from 4360 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 12:
5080 divided by 642 is 7 with a remainder of 586.
Record the quotient 7 as the next digit in the result. 
Result so far: 128878.4267
The remainder is 586 after subtracting 4494 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Step 13:
The number 642 fits into 5860 9 times, leaving a remainder of 82.
The next digit of our result is 9. 
Result so far: 128878.42679
If we take 5778 away from 5860, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 14:
When dividing 820 by 642, we get 1 with a remainder of 178.
Write down 1 as next digit of the result. 
Result so far: 128878.426791
If we take 642 away from 820, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 15:
642 can be fit into 1780 2 times, resulting in a remainder of 496.
Record the quotient 2 as the next digit in the result. 
Result so far: 128878.4267912
If we subtract 1284 from 1780, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 16:
642 can be fit into 4960 7 times, resulting in a remainder of 466.
Record the quotient 7 as the next digit in the result. 
Result so far: 128878.42679127
Deduct 4494 from 4960 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Our division results in 128878.42679127 with a remaining 4.66e-07.
