We divide 23187809 by 312
Let's see how many times 312 fits into 23187809.

Let's proceed to step 1:
When dividing 2 by 312, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 312

Going ahead to step 2:
The number 312 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 312

Advancing to step 3:
The number 312 fits into 231 0 times, leaving a remainder of 231.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 231, we end up with 231.
Grab the next digit (8) from the dividend, add it to 231, then carry on: 2318 / 312

On to step 4:
The number 312 fits into 2318 7 times, leaving a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 2184 from 2318 leaves us with 134.
Fetch the next digit (7) from the dividend, attach it to 134 and continue: 1347 / 312

On to step 5:
312 goes into 1347 4 times with a remainder of 99.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 1248 from 1347 to get 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 312

Moving on to step 6:
When dividing 998 by 312, we get 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 743.0
Subtracting 936 from 998 leaves us with 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 312

On to step 7:
The number 312 fits into 620 1 times, leaving a remainder of 308.
Record the quotient 1 as the next digit in the result. 
Result so far: 7431.0
Deduct 312 from 620 and we're left with 308.
Append the next digit (9) from the dividend to 308 and continue with: 3089 / 312

On to step 8:
3089 divided by 312 is 9 with a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 74319.0
If we take 2808 away from 3089, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 9:
2810 divided by 312 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 74319.9
Deduct 2808 from 2810 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
When dividing 20 by 312, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 74319.9
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 312, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 74319.9
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 74319.9 with a balance of 0.02.
