8955799 ÷ 642 
Let's see how many times 642 fits into 8955799.

Going ahead to step 1:
642 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 642

Let's proceed to step 2:
When dividing 89 by 642, we get 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Fetch the next digit (5) from the dividend, attach it to 89 and continue: 895 / 642

Let's proceed to step 3:
642 can be fit into 895 1 times, resulting in a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 642 away from 895, we end up with 253.
Fetch the next digit (5) from the dividend, attach it to 253 and continue: 2535 / 642

On to step 4:
The number 642 fits into 2535 3 times, leaving a remainder of 609.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1926 from 2535 leaves us with 609.
Append the next digit (7) from the dividend to 609 and continue with: 6097 / 642

Let's proceed to step 5:
642 goes into 6097 9 times with a remainder of 319.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Deduct 5778 from 6097 and we're left with 319.
Take the next digit (9) from the dividend and append it to 319, then repeat: 3199 / 642

Advancing to step 6:
The number 642 fits into 3199 4 times, leaving a remainder of 631.
Use 4 as the next digit of our solution. 
Result so far: 1394.0
The remainder is 631 after subtracting 2568 from 3199.
Take the next digit (9) from the dividend and append it to 631, then repeat: 6319 / 642

Going ahead to step 7:
If we divide 6319 by 642, we get 9 and a remainder of 541.
Write down 9 as next digit of the result. 
Result so far: 13949.0
Subtracting 5778 from 6319 leaves us with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

On to step 8:
When dividing 5410 by 642, we get 8 with a remainder of 274.
Record the quotient 8 as the next digit in the result. 
Result so far: 13949.8
Deduct 5136 from 5410 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 9:
If we divide 2740 by 642, we get 4 and a remainder of 172.
Use 4 as the next digit of our solution. 
Result so far: 13949.84
If we subtract 2568 from 2740, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
642 can be fit into 1720 2 times, resulting in a remainder of 436.
The number 2 becomes the next digit in our result. 
Result so far: 13949.842
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.

Going ahead to step 11:
642 goes into 4360 6 times with a remainder of 508.
The next digit of our result is 6. 
Result so far: 13949.8426
If we subtract 3852 from 4360, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 12:
642 can be fit into 5080 7 times, resulting in a remainder of 586.
Put 7 as the next digit of the answer. 
Result so far: 13949.84267
Subtracting 4494 from 5080 leaves us with 586.
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:
642 can be fit into 5860 9 times, resulting in a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 13949.842679
The remainder is 82 after subtracting 5778 from 5860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 14:
642 goes into 820 1 times with a remainder of 178.
The number 1 becomes the next digit in our result. 
Result so far: 13949.8426791
Subtract 642 from 820 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 15:
The number 642 fits into 1780 2 times, leaving a remainder of 496.
The next digit of our result is 2. 
Result so far: 13949.84267912
If we take 1284 away from 1780, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final result is 13949.84267912 with a remainder of 4.96e-07.
