55316940 ÷ 642 
Let's see how many times 642 fits into 55316940.

Advancing to step 1:
When dividing 5 by 642, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 642

Going ahead to step 2:
55 divided by 642 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 642

Let's proceed to step 3:
642 can be fit into 553 0 times, resulting in a remainder of 553.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 553 and we're left with 553.
Fetch the next digit (1) from the dividend, attach it to 553 and continue: 5531 / 642

Step 4:
642 can be fit into 5531 8 times, resulting in a remainder of 395.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 5136 away from 5531, we end up with 395.
Append the next digit (6) from the dividend to 395 and continue with: 3956 / 642

Let's proceed to step 5:
The number 642 fits into 3956 6 times, leaving a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtract 3852 from 3956 to get 104.
Fetch the next digit (9) from the dividend, attach it to 104 and continue: 1049 / 642

Advancing to step 6:
The number 642 fits into 1049 1 times, leaving a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 861.0
The remainder is 407 after subtracting 642 from 1049.
Append the next digit (4) from the dividend to 407 and continue with: 4074 / 642

Step 7:
The number 642 fits into 4074 6 times, leaving a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 8616.0
Subtracting 3852 from 4074 leaves us with 222.
Include the next digit (0) from the dividend after 222, then repeat: 2220 / 642

Going ahead to step 8:
If we divide 2220 by 642, we get 3 and a remainder of 294.
The number 3 becomes the next digit in our result. 
Result so far: 86163.0
Subtract 1926 from 2220 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 9:
642 goes into 2940 4 times with a remainder of 372.
Use 4 as the next digit of our solution. 
Result so far: 86163.4
If we take 2568 away from 2940, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 10:
642 can be fit into 3720 5 times, resulting in a remainder of 510.
The number 5 becomes the next digit in our result. 
Result so far: 86163.45
Deduct 3210 from 3720 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 11:
When dividing 5100 by 642, we get 7 with a remainder of 606.
Record the quotient 7 as the next digit in the result. 
Result so far: 86163.457
The remainder is 606 after subtracting 4494 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 12:
6060 divided by 642 is 9 with a remainder of 282.
Write down 9 as next digit of the result. 
Result so far: 86163.4579
Deduct 5778 from 6060 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 13:
If we divide 2820 by 642, we get 4 and a remainder of 252.
Put 4 as the next digit of the answer. 
Result so far: 86163.45794
The remainder is 252 after subtracting 2568 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 14:
642 goes into 2520 3 times with a remainder of 594.
The number 3 becomes the next digit in our result. 
Result so far: 86163.457943
Deduct 1926 from 2520 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Let's proceed to step 15:
642 can be fit into 5940 9 times, resulting in a remainder of 162.
Use 9 as the next digit of our solution. 
Result so far: 86163.4579439
Deduct 5778 from 5940 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 16:
If we divide 1620 by 642, we get 2 and a remainder of 336.
The number 2 becomes the next digit in our result. 
Result so far: 86163.45794392
Deduct 1284 from 1620 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 86163.45794392 with a remainder of 3.36e-07.
