We look at the division of 30223914 by 643 
Our goal is to divide 30223914 by 643.

On to step 1:
If we divide 3 by 643, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 643

Step 2:
The number 643 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 643

Let's proceed to step 3:
302 divided by 643 is 0 with a remainder of 302.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 302 after subtracting 0 from 302.
Grab the next digit (2) from the dividend, add it to 302, then carry on: 3022 / 643

Moving on to step 4:
When dividing 3022 by 643, we get 4 with a remainder of 450.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2572 away from 3022, we end up with 450.
Grab the next digit (3) from the dividend, add it to 450, then carry on: 4503 / 643

Moving on to step 5:
4503 divided by 643 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtract 4501 from 4503 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 643

Let's proceed to step 6:
643 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 470.0
The remainder is 29 after subtracting 0 from 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 643

Going ahead to step 7:
When dividing 291 by 643, we get 0 with a remainder of 291.
Put 0 as the next digit of the answer. 
Result so far: 4700.0
Deduct 0 from 291 and we're left with 291.
Bring next digit (4) of the dividend behind the 291 and repeat the process: 2914 / 643

Advancing to step 8:
When dividing 2914 by 643, we get 4 with a remainder of 342.
Use 4 as the next digit of our solution. 
Result so far: 47004.0
If we subtract 2572 from 2914, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 9:
If we divide 3420 by 643, we get 5 and a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 47004.5
Deduct 3215 from 3420 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 10:
2050 divided by 643 is 3 with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 47004.53
Subtracting 1929 from 2050 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 11:
1210 divided by 643 is 1 with a remainder of 567.
Write down 1 as next digit of the result. 
Result so far: 47004.531
Subtracting 643 from 1210 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Let's proceed to step 12:
5670 divided by 643 is 8 with a remainder of 526.
The number 8 becomes the next digit in our result. 
Result so far: 47004.5318
If we take 5144 away from 5670, we end up with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 13:
5260 divided by 643 is 8 with a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 47004.53188
The remainder is 116 after subtracting 5144 from 5260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 47004.53188, with a leftover of 0.000116.
