We're dividing 30618983 by 641 
Let's see how many times 641 fits into 30618983.

Going ahead to step 1:
641 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 641

Moving on to step 2:
The number 641 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 641

On to step 3:
When dividing 306 by 641, we get 0 with a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 306 and we're left with 306.
Include the next digit (1) from the dividend after 306, then repeat: 3061 / 641

On to step 4:
If we divide 3061 by 641, we get 4 and a remainder of 497.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 497 after subtracting 2564 from 3061.
Bring next digit (8) of the dividend behind the 497 and repeat the process: 4978 / 641

Step 5:
If we divide 4978 by 641, we get 7 and a remainder of 491.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 4487 from 4978, we get 491.
Bring next digit (9) of the dividend behind the 491 and repeat the process: 4919 / 641

Going ahead to step 6:
641 goes into 4919 7 times with a remainder of 432.
The next digit of our result is 7. 
Result so far: 477.0
If we subtract 4487 from 4919, we get 432.
Bring next digit (8) of the dividend behind the 432 and repeat the process: 4328 / 641

Step 7:
4328 divided by 641 is 6 with a remainder of 482.
The next digit of our result is 6. 
Result so far: 4776.0
The remainder is 482 after subtracting 3846 from 4328.
Bring next digit (3) of the dividend behind the 482 and repeat the process: 4823 / 641

Step 8:
The number 641 fits into 4823 7 times, leaving a remainder of 336.
Use 7 as the next digit of our solution. 
Result so far: 47767.0
Subtract 4487 from 4823 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 9:
When dividing 3360 by 641, we get 5 with a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 47767.5
Subtracting 3205 from 3360 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 10:
The number 641 fits into 1550 2 times, leaving a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 47767.52
Subtract 1282 from 1550 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 11:
When dividing 2680 by 641, we get 4 with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 47767.524
If we take 2564 away from 2680, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 12:
1160 divided by 641 is 1 with a remainder of 519.
The number 1 becomes the next digit in our result. 
Result so far: 47767.5241
Subtracting 641 from 1160 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 13:
641 can be fit into 5190 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 47767.52418
Subtract 5128 from 5190 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 14:
The number 641 fits into 620 0 times, leaving a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 47767.52418
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 15:
If we divide 6200 by 641, we get 9 and a remainder of 431.
The next digit of our result is 9. 
Result so far: 47767.5241809
The remainder is 431 after subtracting 5769 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 16:
4310 divided by 641 is 6 with a remainder of 464.
The next digit of our result is 6. 
Result so far: 47767.52418096
Deduct 3846 from 4310 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

After the division, we end up with 47767.52418096 and a remainder of 4.64e-07.
