840430 divided by 73 
We want to figure out the number of times 840430 can be divided by 73.

On to step 1:
If we divide 8 by 73, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 73

Advancing to step 2:
84 divided by 73 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 73 from 84 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 73

Let's proceed to step 3:
73 goes into 110 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 73 from 110 and we're left with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 73

Let's proceed to step 4:
If we divide 374 by 73, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 115.0
Subtract 365 from 374 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 73

On to step 5:
73 can be fit into 93 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1151.0
Subtracting 73 from 93 leaves us with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 73

Going ahead to step 6:
73 goes into 200 2 times with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 11512.0
Subtract 146 from 200 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
73 goes into 540 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 11512.7
Deduct 511 from 540 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
73 can be fit into 290 3 times, resulting in a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 11512.73
Subtracting 219 from 290 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
73 goes into 710 9 times with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 11512.739
If we take 657 away from 710, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
The number 73 fits into 530 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 11512.7397
Subtracting 511 from 530 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
73 goes into 190 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 11512.73972
The remainder is 44 after subtracting 146 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
440 divided by 73 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 11512.739726
Subtract 438 from 440 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
73 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11512.739726
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 73 fits into 200 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 11512.73972602
If we subtract 146 from 200, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 11512.73972602 with a balance of 5.4e-08.
