8138985 ÷ 609 
Our goal is to divide 8138985 by 609.

Going ahead to step 1:
609 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 609

On to step 2:
When dividing 81 by 609, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 609

Going ahead to step 3:
If we divide 813 by 609, we get 1 and a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 609 from 813, we get 204.
Include the next digit (8) from the dividend after 204, then repeat: 2048 / 609

On to step 4:
The number 609 fits into 2048 3 times, leaving a remainder of 221.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1827 from 2048 to get 221.
Grab the next digit (9) from the dividend, add it to 221, then carry on: 2219 / 609

On to step 5:
The number 609 fits into 2219 3 times, leaving a remainder of 392.
Put 3 as the next digit of the answer. 
Result so far: 133.0
Subtracting 1827 from 2219 leaves us with 392.
Grab the next digit (8) from the dividend, add it to 392, then carry on: 3928 / 609

Let's proceed to step 6:
609 goes into 3928 6 times with a remainder of 274.
The next digit of our result is 6. 
Result so far: 1336.0
If we subtract 3654 from 3928, we get 274.
Take the next digit (5) from the dividend and append it to 274, then repeat: 2745 / 609

Going ahead to step 7:
The number 609 fits into 2745 4 times, leaving a remainder of 309.
The next digit of our result is 4. 
Result so far: 13364.0
The remainder is 309 after subtracting 2436 from 2745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 8:
609 goes into 3090 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 13364.5
If we take 3045 away from 3090, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
450 divided by 609 is 0 with a remainder of 450.
Put 0 as the next digit of the answer. 
Result so far: 13364.5
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
When dividing 4500 by 609, we get 7 with a remainder of 237.
The number 7 becomes the next digit in our result. 
Result so far: 13364.507
If we take 4263 away from 4500, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 11:
2370 divided by 609 is 3 with a remainder of 543.
The number 3 becomes the next digit in our result. 
Result so far: 13364.5073
Subtracting 1827 from 2370 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 12:
The number 609 fits into 5430 8 times, leaving a remainder of 558.
Record the quotient 8 as the next digit in the result. 
Result so far: 13364.50738
The remainder is 558 after subtracting 4872 from 5430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 13:
609 can be fit into 5580 9 times, resulting in a remainder of 99.
The next digit of our result is 9. 
Result so far: 13364.507389
If we take 5481 away from 5580, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 14:
The number 609 fits into 990 1 times, leaving a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 13364.5073891
If we take 609 away from 990, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 15:
The number 609 fits into 3810 6 times, leaving a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 13364.50738916
Deduct 3654 from 3810 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.

The quotient of the division is 13364.50738916, and the remainder is 1.56e-07.
