We're dividing 6001986 by 309 
Let's see how many times 309 fits into 6001986.

Advancing to step 1:
If we divide 6 by 309, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 309

Moving on to step 2:
The number 309 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 309

Going ahead to step 3:
The number 309 fits into 600 1 times, leaving a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 309 from 600 and we're left with 291.
Grab the next digit (1) from the dividend, add it to 291, then carry on: 2911 / 309

Step 4:
The number 309 fits into 2911 9 times, leaving a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 2781 from 2911 leaves us with 130.
Append the next digit (9) from the dividend to 130 and continue with: 1309 / 309

On to step 5:
1309 divided by 309 is 4 with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
If we take 1236 away from 1309, we end up with 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 309

On to step 6:
309 goes into 738 2 times with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 1942.0
The remainder is 120 after subtracting 618 from 738.
Append the next digit (6) from the dividend to 120 and continue with: 1206 / 309

Going ahead to step 7:
1206 divided by 309 is 3 with a remainder of 279.
Record the quotient 3 as the next digit in the result. 
Result so far: 19423.0
Deduct 927 from 1206 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 8:
When dividing 2790 by 309, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 19423.9
If we take 2781 away from 2790, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
309 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 19423.9
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
309 can be fit into 900 2 times, resulting in a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 19423.902
If we subtract 618 from 900, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 11:
If we divide 2820 by 309, we get 9 and a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 19423.9029
Subtracting 2781 from 2820 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
When dividing 390 by 309, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 19423.90291
Subtracting 309 from 390 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 13:
If we divide 810 by 309, we get 2 and a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 19423.902912
If we take 618 away from 810, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 14:
309 goes into 1920 6 times with a remainder of 66.
The next digit of our result is 6. 
Result so far: 19423.9029126
Subtract 1854 from 1920 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 15:
When dividing 660 by 309, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 19423.90291262
Deduct 618 from 660 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 19423.90291262 with a remaining 4.2e-08.
