3081806 divided by 642 
We want to figure out the number of times 3081806 can be divided by 642.

Moving on to step 1:
The number 642 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 642

On to step 2:
The number 642 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 642

On to step 3:
642 goes into 308 0 times with a remainder of 308.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 308 after subtracting 0 from 308.
Bring next digit (1) of the dividend behind the 308 and repeat the process: 3081 / 642

Going ahead to step 4:
3081 divided by 642 is 4 with a remainder of 513.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 513 after subtracting 2568 from 3081.
Append the next digit (8) from the dividend to 513 and continue with: 5138 / 642

Let's proceed to step 5:
642 can be fit into 5138 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtract 5136 from 5138 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 642

On to step 6:
When dividing 20 by 642, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
If we subtract 0 from 20, we get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 642

Moving on to step 7:
642 goes into 206 0 times with a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 4800.0
Subtract 0 from 206 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 8:
If we divide 2060 by 642, we get 3 and a remainder of 134.
The number 3 becomes the next digit in our result. 
Result so far: 4800.3
If we subtract 1926 from 2060, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 9:
642 goes into 1340 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 4800.32
If we take 1284 away from 1340, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
When dividing 560 by 642, we get 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 4800.32
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 11:
The number 642 fits into 5600 8 times, leaving a remainder of 464.
Write down 8 as next digit of the result. 
Result so far: 4800.3208
Subtract 5136 from 5600 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 12:
642 goes into 4640 7 times with a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 4800.32087
The remainder is 146 after subtracting 4494 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 13:
642 can be fit into 1460 2 times, resulting in a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 4800.320872
The remainder is 176 after subtracting 1284 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 14:
642 goes into 1760 2 times with a remainder of 476.
The next digit of our result is 2. 
Result so far: 4800.3208722
The remainder is 476 after subtracting 1284 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Our division results in 4800.3208722 with a remaining 4.76e-06.
