We look at the division of 30089087 by 639 
We want to divide 30089087 by 639.

Step 1:
639 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 639

Going ahead to step 2:
If we divide 30 by 639, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 639

Advancing to step 3:
When dividing 300 by 639, we get 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 300, we end up with 300.
Grab the next digit (8) from the dividend, add it to 300, then carry on: 3008 / 639

Let's proceed to step 4:
639 can be fit into 3008 4 times, resulting in a remainder of 452.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2556 away from 3008, we end up with 452.
Include the next digit (9) from the dividend after 452, then repeat: 4529 / 639

Advancing to step 5:
639 goes into 4529 7 times with a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 4473 from 4529 to get 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 639

Going ahead to step 6:
When dividing 560 by 639, we get 0 with a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 470.0
If we take 0 away from 560, we end up with 560.
Bring next digit (8) of the dividend behind the 560 and repeat the process: 5608 / 639

Step 7:
If we divide 5608 by 639, we get 8 and a remainder of 496.
Use 8 as the next digit of our solution. 
Result so far: 4708.0
Subtract 5112 from 5608 to get 496.
Take the next digit (7) from the dividend and append it to 496, then repeat: 4967 / 639

On to step 8:
The number 639 fits into 4967 7 times, leaving a remainder of 494.
Record the quotient 7 as the next digit in the result. 
Result so far: 47087.0
Deduct 4473 from 4967 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 9:
639 can be fit into 4940 7 times, resulting in a remainder of 467.
The number 7 becomes the next digit in our result. 
Result so far: 47087.7
If we take 4473 away from 4940, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 10:
4670 divided by 639 is 7 with a remainder of 197.
Record the quotient 7 as the next digit in the result. 
Result so far: 47087.77
If we subtract 4473 from 4670, we get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The quotient of the division is 47087.77, and the remainder is 0.197.
