Let's divide 15905978 by 306
Let's see how many times 306 fits into 15905978.

Advancing to step 1:
When dividing 1 by 306, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 306

Moving on to step 2:
When dividing 15 by 306, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 306

On to step 3:
The number 306 fits into 159 0 times, leaving a remainder of 159.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 159, we end up with 159.
Fetch the next digit (0) from the dividend, attach it to 159 and continue: 1590 / 306

Let's proceed to step 4:
306 can be fit into 1590 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 1530 from 1590, we get 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 306

Advancing to step 5:
When dividing 605 by 306, we get 1 with a remainder of 299.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we subtract 306 from 605, we get 299.
Append the next digit (9) from the dividend to 299 and continue with: 2999 / 306

Step 6:
The number 306 fits into 2999 9 times, leaving a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
Subtract 2754 from 2999 to get 245.
Bring next digit (7) of the dividend behind the 245 and repeat the process: 2457 / 306

Advancing to step 7:
When dividing 2457 by 306, we get 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 5198.0
Subtract 2448 from 2457 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 306

On to step 8:
306 can be fit into 98 0 times, resulting in a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 51980.0
Subtract 0 from 98 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 9:
If we divide 980 by 306, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 51980.3
Deduct 918 from 980 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
When dividing 620 by 306, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 51980.32
Subtracting 612 from 620 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
306 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 51980.32
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
800 divided by 306 is 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 51980.3202
Subtracting 612 from 800 leaves us 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.

Step 13:
306 goes into 1880 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 51980.32026
If we subtract 1836 from 1880, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
306 can be fit into 440 1 times, resulting in a remainder of 134.
The number 1 becomes the next digit in our result. 
Result so far: 51980.320261
Deduct 306 from 440 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 15:
1340 divided by 306 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 51980.3202614
Deduct 1224 from 1340 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 16:
If we divide 1160 by 306, we get 3 and a remainder of 242.
Record the quotient 3 as the next digit in the result. 
Result so far: 51980.32026143
Subtract 918 from 1160 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Our division results in 51980.32026143 with a remaining 2.42e-07.
