Let's divide 990509 by 71
Our goal is to divide 990509 by 71.

Let's proceed to step 1:
71 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 71

Moving on to step 2:
71 can be fit into 99 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 28 after subtracting 71 from 99.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 71

Moving on to step 3:
71 can be fit into 280 3 times, resulting in a remainder of 67.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 213 from 280 to get 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 71

Step 4:
The number 71 fits into 675 9 times, leaving a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Deduct 639 from 675 and we're left with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 71

Let's proceed to step 5:
360 divided by 71 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1395.0
Subtracting 355 from 360 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 71

Moving on to step 6:
If we divide 59 by 71, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 13950.0
The remainder is 59 after subtracting 0 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
590 divided by 71 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 13950.8
Subtracting 568 from 590 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
71 can be fit into 220 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13950.83
Deduct 213 from 220 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 71 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 13950.83
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
The number 71 fits into 700 9 times, leaving a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 13950.8309
Subtracting 639 from 700 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 11:
When dividing 610 by 71, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 13950.83098
The remainder is 42 after subtracting 568 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
The number 71 fits into 420 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 13950.830985
Deduct 355 from 420 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
650 divided by 71 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 13950.8309859
If we subtract 639 from 650, 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 14:
The number 71 fits into 110 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 13950.83098591
If we subtract 71 from 110, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 13950.83098591, and the remainder is 3.9e-08.
