9550602 ÷ 642 
Our goal is to divide 9550602 by 642.

Moving on to step 1:
9 divided by 642 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 642

Moving on to step 2:
642 goes into 95 0 times with a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 95 after subtracting 0 from 95.
Fetch the next digit (5) from the dividend, attach it to 95 and continue: 955 / 642

On to step 3:
The number 642 fits into 955 1 times, leaving a remainder of 313.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 642 away from 955, we end up with 313.
Grab the next digit (0) from the dividend, add it to 313, then carry on: 3130 / 642

On to step 4:
642 goes into 3130 4 times with a remainder of 562.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 2568 from 3130 to get 562.
Fetch the next digit (6) from the dividend, attach it to 562 and continue: 5626 / 642

Advancing to step 5:
The number 642 fits into 5626 8 times, leaving a remainder of 490.
The next digit of our result is 8. 
Result so far: 148.0
Deduct 5136 from 5626 and we're left with 490.
Bring next digit (0) of the dividend behind the 490 and repeat the process: 4900 / 642

Moving on to step 6:
If we divide 4900 by 642, we get 7 and a remainder of 406.
The next digit of our result is 7. 
Result so far: 1487.0
The remainder is 406 after subtracting 4494 from 4900.
Include the next digit (2) from the dividend after 406, then repeat: 4062 / 642

Moving on to step 7:
642 goes into 4062 6 times with a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 14876.0
Deduct 3852 from 4062 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 8:
When dividing 2100 by 642, we get 3 with a remainder of 174.
The number 3 becomes the next digit in our result. 
Result so far: 14876.3
If we subtract 1926 from 2100, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Advancing to step 9:
642 can be fit into 1740 2 times, resulting in a remainder of 456.
Record the quotient 2 as the next digit in the result. 
Result so far: 14876.32
The remainder is 456 after subtracting 1284 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 10:
If we divide 4560 by 642, we get 7 and a remainder of 66.
The next digit of our result is 7. 
Result so far: 14876.327
Subtracting 4494 from 4560 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
642 can be fit into 660 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 14876.3271
Subtract 642 from 660 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
If we divide 180 by 642, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 14876.3271
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
1800 divided by 642 is 2 with a remainder of 516.
The number 2 becomes the next digit in our result. 
Result so far: 14876.327102
The remainder is 516 after subtracting 1284 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 14:
When dividing 5160 by 642, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 14876.3271028
Subtracting 5136 from 5160 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
When dividing 240 by 642, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 14876.3271028
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 14876.3271028 and a remainder of 2.4e-07.
