Let's divide 40639449 by 73
We're looking to find how many times 73 goes into 40639449.

Advancing to step 1:
73 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 73

Going ahead to step 2:
73 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 73

Advancing to step 3:
73 can be fit into 406 5 times, resulting in a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 365 from 406 to get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 73

Going ahead to step 4:
When dividing 413 by 73, we get 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 365 from 413 and we're left with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 73

Step 5:
489 divided by 73 is 6 with a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
Subtract 438 from 489 to get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 73

Step 6:
The number 73 fits into 514 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 5567.0
If we take 511 away from 514, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 73

Going ahead to step 7:
When dividing 34 by 73, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 55670.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 73

Going ahead to step 8:
73 goes into 349 4 times with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 556704.0
If we subtract 292 from 349, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
73 can be fit into 570 7 times, resulting in a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 556704.7
Subtract 511 from 570 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 10:
73 goes into 590 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 556704.78
If we take 584 away from 590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
73 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 556704.78
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
If we divide 600 by 73, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 556704.7808
Deduct 584 from 600 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
73 can be fit into 160 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 556704.78082
Deduct 146 from 160 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
73 goes into 140 1 times with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 556704.780821
If we subtract 73 from 140, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 15:
73 can be fit into 670 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 556704.7808219
Subtract 657 from 670 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 16:
73 can be fit into 130 1 times, resulting in a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 556704.78082191
If we take 73 away from 130, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 556704.78082191 with a remainder of 5.7e-08.
