821312 divided by 57 
We're looking to find how many times 57 goes into 821312.

Moving on to step 1:
57 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 57

Going ahead to step 2:
57 can be fit into 82 1 times, resulting in a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 57 away from 82, we end up with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 57

On to step 3:
If we divide 251 by 57, we get 4 and a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 23 after subtracting 228 from 251.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 57

Let's proceed to step 4:
If we divide 233 by 57, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Subtract 228 from 233 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 57

Advancing to step 5:
57 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 1440.0
If we subtract 0 from 51, we get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 57

Moving on to step 6:
When dividing 512 by 57, we get 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 14408.0
Deduct 456 from 512 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
The number 57 fits into 560 9 times, leaving a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 14408.9
If we subtract 513 from 560, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
470 divided by 57 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 14408.98
The remainder is 14 after subtracting 456 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
When dividing 140 by 57, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 14408.982
If we subtract 114 from 140, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
The number 57 fits into 260 4 times, leaving a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 14408.9824
Subtracting 228 from 260 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 57, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 14408.98245
Subtracting 285 from 320 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
350 divided by 57 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 14408.982456
Deduct 342 from 350 and we're left 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.

Moving on to step 13:
57 goes into 80 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 14408.9824561
Subtracting 57 from 80 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
230 divided by 57 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14408.98245614
Subtracting 228 from 230 leaves us 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.

The final outcome is 14408.98245614, with a leftover of 2e-09.
