Let's divide 6690618 by 639
We want to figure out the number of times 6690618 can be divided by 639.

Step 1:
639 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 639

Advancing to step 2:
If we divide 66 by 639, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 639

Advancing to step 3:
When dividing 669 by 639, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 639 away from 669, we end up with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 639

Moving on to step 4:
The number 639 fits into 300 0 times, leaving a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 300, we end up with 300.
Grab the next digit (6) from the dividend, add it to 300, then carry on: 3006 / 639

Going ahead to step 5:
If we divide 3006 by 639, we get 4 and a remainder of 450.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we take 2556 away from 3006, we end up with 450.
Include the next digit (1) from the dividend after 450, then repeat: 4501 / 639

Advancing to step 6:
639 goes into 4501 7 times with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 1047.0
Subtract 4473 from 4501 to get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 639

Going ahead to step 7:
639 goes into 288 0 times with a remainder of 288.
The next digit of our result is 0. 
Result so far: 10470.0
Subtract 0 from 288 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 8:
If we divide 2880 by 639, we get 4 and a remainder of 324.
Put 4 as the next digit of the answer. 
Result so far: 10470.4
Deduct 2556 from 2880 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 9:
639 goes into 3240 5 times with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 10470.45
If we subtract 3195 from 3240, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
639 goes into 450 0 times with a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 10470.45
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 11:
When dividing 4500 by 639, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 10470.4507
If we take 4473 away from 4500, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
The number 639 fits into 270 0 times, leaving a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 10470.4507
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
2700 divided by 639 is 4 with a remainder of 144.
The next digit of our result is 4. 
Result so far: 10470.450704
Subtracting 2556 from 2700 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 14:
639 goes into 1440 2 times with a remainder of 162.
The number 2 becomes the next digit in our result. 
Result so far: 10470.4507042
Subtracting 1278 from 1440 leaves us 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.

Moving on to step 15:
639 goes into 1620 2 times with a remainder of 342.
Record the quotient 2 as the next digit in the result. 
Result so far: 10470.45070422
The remainder is 342 after subtracting 1278 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The quotient of the division is 10470.45070422, and the remainder is 3.42e-07.
