We look at the division of 12308723 by 57 
We're looking to find how many times 57 goes into 12308723.

On to step 1:
The number 57 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.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 57

Going ahead to step 2:
57 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 57

Let's proceed to step 3:
123 divided by 57 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 114 from 123 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 57

Let's proceed to step 4:
90 divided by 57 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 57 away from 90, we end up with 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 57

Going ahead to step 5:
The number 57 fits into 338 5 times, leaving a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 215.0
If we take 285 away from 338, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 57

Going ahead to step 6:
57 goes into 537 9 times with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 2159.0
If we take 513 away from 537, we end up with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 57

Step 7:
242 divided by 57 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 21594.0
Deduct 228 from 242 and we're left with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 57

Step 8:
57 goes into 143 2 times with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 215942.0
The remainder is 29 after subtracting 114 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
57 goes into 290 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 215942.5
Deduct 285 from 290 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
57 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 215942.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
500 divided by 57 is 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 215942.508
Subtracting 456 from 500 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
The number 57 fits into 440 7 times, leaving a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 215942.5087
Deduct 399 from 440 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
The number 57 fits into 410 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 215942.50877
If we take 399 away from 410, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 215942.50877 with a remainder of 1.1e-05.
