Let's divide 81673489 by 73
We want to figure out the number of times 81673489 can be divided by 73.

Moving on to step 1:
When dividing 8 by 73, we get 0 with 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.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 73

Moving on to step 2:
73 goes into 81 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 73 from 81 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 73

On to step 3:
73 goes into 86 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 73 away from 86, we end up with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 73

Going ahead to step 4:
137 divided by 73 is 1 with a remainder of 64.
The next digit of our result is 1. 
Result so far: 111.0
Deduct 73 from 137 and we're left with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 73

On to step 5:
When dividing 643 by 73, we get 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 1118.0
Deduct 584 from 643 and we're left with 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 73

Step 6:
If we divide 594 by 73, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 11188.0
Subtract 584 from 594 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 73

Let's proceed to step 7:
73 goes into 108 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 111881.0
If we take 73 away from 108, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 73

Let's proceed to step 8:
73 can be fit into 359 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 1118814.0
The remainder is 67 after subtracting 292 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
73 can be fit into 670 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 1118814.9
Subtracting 657 from 670 leaves us with 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 10:
The number 73 fits into 130 1 times, leaving a remainder of 57.
The next digit of our result is 1. 
Result so far: 1118814.91
Deduct 73 from 130 and we're left 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.

Advancing to step 11:
If we divide 570 by 73, we get 7 and a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 1118814.917
Deduct 511 from 570 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
If we divide 590 by 73, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 1118814.9178
Subtracting 584 from 590 leaves us 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.

Step 13:
When dividing 60 by 73, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1118814.9178
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.

Let's proceed to step 14:
If we divide 600 by 73, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1118814.917808
The remainder is 16 after subtracting 584 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 15:
When dividing 160 by 73, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 1118814.9178082
If we subtract 146 from 160, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 16:
140 divided by 73 is 1 with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 1118814.91780821
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.

Our division results in 1118814.91780821 with a remaining 6.7e-08.
