Let's divide 643464 by 73
Our goal is to divide 643464 by 73.

Going ahead to step 1:
If we divide 6 by 73, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 73

Step 2:
The number 73 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 73

Going ahead to step 3:
73 goes into 643 8 times with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 584 from 643 to get 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 73

Let's proceed to step 4:
The number 73 fits into 594 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 88.0
Deduct 584 from 594 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 73

Moving on to step 5:
73 can be fit into 106 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 881.0
Deduct 73 from 106 and we're left with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 73

On to step 6:
73 can be fit into 334 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 8814.0
The remainder is 42 after subtracting 292 from 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
If we divide 420 by 73, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8814.5
If we take 365 away from 420, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
550 divided by 73 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 8814.57
Subtract 511 from 550 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
390 divided by 73 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8814.575
Subtract 365 from 390 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
The number 73 fits into 250 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 8814.5753
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
73 can be fit into 310 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 8814.57534
Subtracting 292 from 310 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
73 can be fit into 180 2 times, resulting in a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 8814.575342
Deduct 146 from 180 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
The number 73 fits into 340 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8814.5753424
If we take 292 away from 340, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
If we divide 480 by 73, we get 6 and a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 8814.57534246
Subtracting 438 from 480 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 8814.57534246, with a leftover of 4.2e-08.
