We divide 3877318 by 509
We're looking to find how many times 509 goes into 3877318.

Advancing to step 1:
If we divide 3 by 509, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 509

On to step 2:
509 goes into 38 0 times with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 509

On to step 3:
When dividing 387 by 509, we get 0 with a remainder of 387.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 387 leaves us with 387.
Fetch the next digit (7) from the dividend, attach it to 387 and continue: 3877 / 509

Step 4:
The number 509 fits into 3877 7 times, leaving a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 3563 from 3877 and we're left with 314.
Fetch the next digit (3) from the dividend, attach it to 314 and continue: 3143 / 509

Step 5:
If we divide 3143 by 509, we get 6 and a remainder of 89.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 3054 from 3143, we get 89.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 509

Let's proceed to step 6:
The number 509 fits into 891 1 times, leaving a remainder of 382.
Put 1 as the next digit of the answer. 
Result so far: 761.0
If we take 509 away from 891, we end up with 382.
Bring next digit (8) of the dividend behind the 382 and repeat the process: 3828 / 509

Going ahead to step 7:
509 can be fit into 3828 7 times, resulting in a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 7617.0
The remainder is 265 after subtracting 3563 from 3828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 8:
If we divide 2650 by 509, we get 5 and a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 7617.5
If we subtract 2545 from 2650, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
The number 509 fits into 1050 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 7617.52
Subtracting 1018 from 1050 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
When dividing 320 by 509, we get 0 with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 7617.52
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
509 can be fit into 3200 6 times, resulting in a remainder of 146.
Write down 6 as next digit of the result. 
Result so far: 7617.5206
If we subtract 3054 from 3200, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 12:
509 goes into 1460 2 times with a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 7617.52062
Deduct 1018 from 1460 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Moving on to step 13:
509 can be fit into 4420 8 times, resulting in a remainder of 348.
The next digit of our result is 8. 
Result so far: 7617.520628
If we take 4072 away from 4420, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 14:
3480 divided by 509 is 6 with a remainder of 426.
Put 6 as the next digit of the answer. 
Result so far: 7617.5206286
Subtract 3054 from 3480 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 15:
When dividing 4260 by 509, we get 8 with a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 7617.52062868
If we take 4072 away from 4260, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

After the division, we end up with 7617.52062868 and a remainder of 1.88e-07.
