We divide 311989 by 73
We want to divide 311989 by 73.

Moving on to step 1:
If we divide 3 by 73, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 73

Moving on to step 2:
31 divided by 73 is 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 73

Let's proceed to step 3:
73 goes into 311 4 times with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 292 from 311, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 73

Advancing to step 4:
73 goes into 199 2 times with a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 146 from 199, we get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 73

Let's proceed to step 5:
538 divided by 73 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 427.0
The remainder is 27 after subtracting 511 from 538.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 73

On to step 6:
The number 73 fits into 279 3 times, leaving a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 4273.0
Deduct 219 from 279 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.

Step 7:
73 can be fit into 600 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 4273.8
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.

On to step 8:
73 goes into 160 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 4273.82
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.

Going ahead to step 9:
The number 73 fits into 140 1 times, leaving a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 4273.821
The remainder is 67 after subtracting 73 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 10:
670 divided by 73 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 4273.8219
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.

Step 11:
If we divide 130 by 73, we get 1 and a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 4273.82191
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.

Moving on to step 12:
The number 73 fits into 570 7 times, leaving a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 4273.821917
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.

Step 13:
73 goes into 590 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 4273.8219178
Deduct 584 from 590 and we're left 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.

Going ahead to step 14:
60 divided by 73 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 4273.8219178
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 4273.8219178 with a remainder of 6e-08.
