We divide 55358906 by 642
We want to divide 55358906 by 642.

Step 1:
If we divide 5 by 642, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 642

Advancing to step 2:
If we divide 55 by 642, we get 0 and a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 642

Going ahead to step 3:
When dividing 553 by 642, we get 0 with a remainder of 553.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 553 after subtracting 0 from 553.
Append the next digit (5) from the dividend to 553 and continue with: 5535 / 642

Let's proceed to step 4:
642 can be fit into 5535 8 times, resulting in a remainder of 399.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 399 after subtracting 5136 from 5535.
Fetch the next digit (8) from the dividend, attach it to 399 and continue: 3998 / 642

On to step 5:
642 goes into 3998 6 times with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtract 3852 from 3998 to get 146.
Grab the next digit (9) from the dividend, add it to 146, then carry on: 1469 / 642

Moving on to step 6:
When dividing 1469 by 642, we get 2 with a remainder of 185.
Put 2 as the next digit of the answer. 
Result so far: 862.0
If we take 1284 away from 1469, we end up with 185.
Append the next digit (0) from the dividend to 185 and continue with: 1850 / 642

Moving on to step 7:
642 can be fit into 1850 2 times, resulting in a remainder of 566.
Put 2 as the next digit of the answer. 
Result so far: 8622.0
The remainder is 566 after subtracting 1284 from 1850.
Fetch the next digit (6) from the dividend, attach it to 566 and continue: 5666 / 642

Step 8:
5666 divided by 642 is 8 with a remainder of 530.
Write down 8 as next digit of the result. 
Result so far: 86228.0
Subtract 5136 from 5666 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
642 goes into 5300 8 times with a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 86228.8
If we take 5136 away from 5300, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
642 can be fit into 1640 2 times, resulting in a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 86228.82
The remainder is 356 after subtracting 1284 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 11:
The number 642 fits into 3560 5 times, leaving a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 86228.825
If we subtract 3210 from 3560, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
When dividing 3500 by 642, we get 5 with a remainder of 290.
The next digit of our result is 5. 
Result so far: 86228.8255
Subtracting 3210 from 3500 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The quotient of the division is 86228.8255, and the remainder is 0.0029.
