We divide 669402 by 509
We want to divide 669402 by 509.

On to step 1:
If we divide 6 by 509, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 509

Moving on to step 2:
If we divide 66 by 509, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 509

Moving on to step 3:
The number 509 fits into 669 1 times, leaving a remainder of 160.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 509 from 669 leaves us with 160.
Grab the next digit (4) from the dividend, add it to 160, then carry on: 1604 / 509

Advancing to step 4:
If we divide 1604 by 509, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1527 from 1604 leaves us with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 509

Moving on to step 5:
770 divided by 509 is 1 with a remainder of 261.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we subtract 509 from 770, we get 261.
Append the next digit (2) from the dividend to 261 and continue with: 2612 / 509

On to step 6:
509 can be fit into 2612 5 times, resulting in a remainder of 67.
The next digit of our result is 5. 
Result so far: 1315.0
If we take 2545 away from 2612, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
When dividing 670 by 509, we get 1 with a remainder of 161.
Use 1 as the next digit of our solution. 
Result so far: 1315.1
If we take 509 away from 670, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 8:
509 can be fit into 1610 3 times, resulting in a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 1315.13
The remainder is 83 after subtracting 1527 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 9:
The number 509 fits into 830 1 times, leaving a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 1315.131
Subtracting 509 from 830 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 10:
If we divide 3210 by 509, we get 6 and a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 1315.1316
Deduct 3054 from 3210 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
The number 509 fits into 1560 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 1315.13163
Subtracting 1527 from 1560 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
When dividing 330 by 509, we get 0 with a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 1315.13163
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 13:
509 can be fit into 3300 6 times, resulting in a remainder of 246.
Record the quotient 6 as the next digit in the result. 
Result so far: 1315.1316306
If we subtract 3054 from 3300, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 14:
509 goes into 2460 4 times with a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 1315.13163064
If we take 2036 away from 2460, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 1315.13163064, with a leftover of 4.24e-07.
