We look at the division of 391072 by 73 
We want to figure out the number of times 391072 can be divided by 73.

On to step 1:
The number 73 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 73

Advancing to step 2:
The number 73 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 73

Going ahead to step 3:
73 goes into 391 5 times with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 365 from 391 leaves us with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 73

Moving on to step 4:
The number 73 fits into 260 3 times, leaving a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 219 from 260 leaves us with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 73

Let's proceed to step 5:
When dividing 417 by 73, we get 5 with a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 535.0
Deduct 365 from 417 and we're left with 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 73

Step 6:
73 goes into 522 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 5357.0
If we subtract 511 from 522, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 73, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 5357.1
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
If we divide 370 by 73, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5357.15
Subtract 365 from 370 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
73 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 5357.15
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 73 is 6 with a remainder of 62.
The next digit of our result is 6. 
Result so far: 5357.1506
If we subtract 438 from 500, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
73 can be fit into 620 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 5357.15068
Deduct 584 from 620 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
360 divided by 73 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 5357.150684
Subtract 292 from 360 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
If we divide 680 by 73, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 5357.1506849
Deduct 657 from 680 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
When dividing 230 by 73, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 5357.15068493
The remainder is 11 after subtracting 219 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 5357.15068493 and a remainder of 1.1e-08.
