We look at the division of 12532599 by 312 
We want to divide 12532599 by 312.

Moving on to step 1:
312 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 312

Advancing to step 2:
When dividing 12 by 312, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 312

Going ahead to step 3:
If we divide 125 by 312, we get 0 and a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 125 leaves us with 125.
Take the next digit (3) from the dividend and append it to 125, then repeat: 1253 / 312

Step 4:
When dividing 1253 by 312, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 5 after subtracting 1248 from 1253.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 312

Step 5:
The number 312 fits into 52 0 times, leaving a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 312

Step 6:
312 goes into 525 1 times with a remainder of 213.
Write down 1 as next digit of the result. 
Result so far: 401.0
Subtract 312 from 525 to get 213.
Bring next digit (9) of the dividend behind the 213 and repeat the process: 2139 / 312

Let's proceed to step 7:
312 goes into 2139 6 times with a remainder of 267.
The number 6 becomes the next digit in our result. 
Result so far: 4016.0
Subtract 1872 from 2139 to get 267.
Fetch the next digit (9) from the dividend, attach it to 267 and continue: 2679 / 312

Moving on to step 8:
312 goes into 2679 8 times with a remainder of 183.
Put 8 as the next digit of the answer. 
Result so far: 40168.0
If we take 2496 away from 2679, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 9:
312 goes into 1830 5 times with a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 40168.5
Deduct 1560 from 1830 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
The number 312 fits into 2700 8 times, leaving a remainder of 204.
The next digit of our result is 8. 
Result so far: 40168.58
Subtracting 2496 from 2700 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
The number 312 fits into 2040 6 times, leaving a remainder of 168.
The next digit of our result is 6. 
Result so far: 40168.586
If we take 1872 away from 2040, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
312 goes into 1680 5 times with a remainder of 120.
The next digit of our result is 5. 
Result so far: 40168.5865
If we subtract 1560 from 1680, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
If we divide 1200 by 312, we get 3 and a remainder of 264.
Record the quotient 3 as the next digit in the result. 
Result so far: 40168.58653
If we subtract 936 from 1200, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 14:
312 can be fit into 2640 8 times, resulting in a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 40168.586538
Deduct 2496 from 2640 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 15:
The number 312 fits into 1440 4 times, leaving a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 40168.5865384
If we take 1248 away from 1440, 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.

Let's proceed to step 16:
312 can be fit into 1920 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 40168.58653846
If we subtract 1872 from 1920, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 40168.58653846 and a remainder of 4.8e-08.
