12737687 ÷ 316 
We want to divide 12737687 by 316.

On to step 1:
The number 316 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 316

Advancing to step 2:
If we divide 12 by 316, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 316

On to step 3:
If we divide 127 by 316, we get 0 and a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 127 after subtracting 0 from 127.
Include the next digit (3) from the dividend after 127, then repeat: 1273 / 316

On to step 4:
When dividing 1273 by 316, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 9 after subtracting 1264 from 1273.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 316

Moving on to step 5:
If we divide 97 by 316, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 97 and we're left with 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 316

Let's proceed to step 6:
316 goes into 976 3 times with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 403.0
If we subtract 948 from 976, we get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 316

On to step 7:
When dividing 288 by 316, we get 0 with a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 4030.0
Subtracting 0 from 288 leaves us with 288.
Take the next digit (7) from the dividend and append it to 288, then repeat: 2887 / 316

Moving on to step 8:
316 can be fit into 2887 9 times, resulting in a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 40309.0
Deduct 2844 from 2887 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
316 can be fit into 430 1 times, resulting in a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 40309.1
Subtracting 316 from 430 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
316 can be fit into 1140 3 times, resulting in a remainder of 192.
Put 3 as the next digit of the answer. 
Result so far: 40309.13
Subtract 948 from 1140 to get 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 11:
1920 divided by 316 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 40309.136
Subtract 1896 from 1920 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
316 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 40309.136
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
The number 316 fits into 2400 7 times, leaving a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 40309.13607
The remainder is 188 after subtracting 2212 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 14:
316 can be fit into 1880 5 times, resulting in a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 40309.136075
If we take 1580 away from 1880, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
When dividing 3000 by 316, we get 9 with a remainder of 156.
Put 9 as the next digit of the answer. 
Result so far: 40309.1360759
Deduct 2844 from 3000 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.

Step 16:
If we divide 1560 by 316, we get 4 and a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 40309.13607594
Deduct 1264 from 1560 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The quotient of the division is 40309.13607594, and the remainder is 2.96e-07.
